Automations let ExtendLM run a sequence of actions manually, on a schedule, or when something changes. Use this guide to add your own automation, choose its steps, and control when it runs. A complete daily research example appears at the end.

Before you start

Enable ExtendLM and sign into the Google account you want to use. Choose the correct account for each notebook or AI service. Available actions and usage limits depend on that account.

1. Open Automations

Open ExtendLM’s extension popup, choose Manage Notebooks, then select Automations in the sidebar. The Automations tab contains your saved automations and their editor.

2. Add a new automation

Click New automation. Choose Blank automation to start from scratch, or select a template. Enter a name in the Steps tab. Templates provide linked steps; review their notebook choices, settings, and required inputs before saving.

3. Add and configure steps

Click Add step. Search the action list or filter it by section. Select an action, fill its required fields, and use Choose notebook when offered. Give each step a unique ID. Empty optional fields use their displayed defaults.

Use a field’s suggestions to select a run input or an earlier step’s output. Steps run from top to bottom; use the step menu to change their order. Save each step after configuring it.

4. Choose when it runs

With no triggers, the automation runs when you click Run. To start it automatically, click Add trigger, choose an event or a schedule, and configure the options and filters shown.

Schedules use your browser’s time zone and are checked every ten minutes while it is open. Choose whether to run once after a missed time or skip it. Keep your computer awake for scheduled runs.

Optional: add run inputs

Use Add input for values that change between manual runs. Set the type, required setting, and default, then connect the input to a step’s field. Scheduled runs need configured values or defaults.

5. Save and test

Click Save in the automation toolbar. Review and confirm any steps that delete or move data when prompted. Auto-save pauses for changes that introduce unconfirmed deletion steps.

Keep Enabled checked and click Run. Enter any requested inputs. Select the run in Runs to check each step’s status, and open Log for errors and details.

Optional: use an existing YAML automation

If you already have automation YAML, open the YAML tab and paste it. Review its notebooks, accounts, and steps, then save and confirm. The Steps and YAML tabs edit the same automation.

Manage the automation

Keep Enabled checked for future scheduled runs. Click a step or the trigger’s pencil icon to edit settings, then save changes. Clear Enabled to stop future triggers. You can also choose completion or failure notifications. Scheduled runs cannot ask you for values: configure step values or defaults for any run inputs.

Troubleshooting

If saving fails, check required fields and unique Step IDs. If Run is unavailable, save changes and check Enabled. For failed runs, inspect Runs and Log. For missed schedules, check the time zone, browser status, and missed-run setting.

Example: daily research at noon

This complete example uses a specified notebook: every day at noon, run Deep Research on a topic, generate a Report artifact, then delete the sources returned by research. The example topic is battery recycling; replace it with your own.

Keep ExtendLM enabled and sign into the Google account that owns the notebook. Create a dedicated notebook for this example. Deep Research and artifact generation use your NotebookLM account’s available features and limits. Scheduled runs need the browser open; your computer must be awake.

1. Create the automation

Open ExtendLM’s popup, open Manage Notebooks, and choose Automations in the sidebar. Click New automation, then Blank automation. In the Steps tab, enter a descriptive name, such as Daily noon research report. This example writes the notebook and topic into the steps, so no run inputs are needed.

2. Schedule it for noon

Click Add trigger. Choose On a schedule, set Repeat to Every day, and set Time to 12:00 PM (12:00). For a missed run, choose Run once when the browser is open again, or Skip it if you only want future runs. Click Add.

Times use your browser’s time zone. Schedules are checked every ten minutes while the browser is open, so a noon run may start after 12:00. Deep Research and report generation take additional time; noon is the start time, not the report delivery time.

3. Run Deep Research

Click Add step and select notebook.research.run in Research. Use the settings below. Click Choose notebook, select the correct account if offered, and select your notebook. In query, enter your topic; for example:

• Step ID: research
• source: web
• mode: deep

Research recent advances in battery recycling. Focus on practical methods, new findings, and their publication dates.

In import, enter these two lines. They import discovered web sources and wait for them to finish processing. Then save the step.

strategy: urls
wait_until: ready

4. Generate a Report artifact

Add notebook.artifact.generate. Set the fields below explicitly, replacing any suggested source value. The expressions connect this step to the research step; copy them exactly, including the braces. Keep the Step IDs shown in this guide so the connections work.

• Step ID: report
• notebook: ${{ steps.research.outputs.notebook }}
• sources: ${{ steps.research.outputs.imported_sources }}
• kind: report
• wait_until: ready
• output_format: document

Leave output_format empty to use document, or select document explicitly. Optionally set language and prompt to request a concise daily briefing with key findings, publication dates, practical implications, and citations. Keep wait_until set to ready so the next step starts only after generation finishes. Save the step.

5. Delete the imported sources

Add notebook.source.delete as the last step. Use the same notebook and imported_sources expressions below. This scopes cleanup to the source list returned by the research step; do not replace it with every source in the notebook.

• Step ID: cleanup
• notebook: ${{ steps.research.outputs.notebook }}
• sources: ${{ steps.research.outputs.imported_sources }}

Keep the research, report, and cleanup steps in that order. Leave Continue after an error off for research and report: if either fails, the run stops before cleanup. The generated report remains in the notebook.

Failed web imports can remain outside the research step’s returned source list. Check Sources after the run and remove any failed entries manually if needed.

6. Save and confirm cleanup

Click Save in the automation toolbar. Review the confirmation listing cleanup and notebook.source.delete, then choose Confirm and save. Auto-save pauses when a change introduces unconfirmed deletion steps; use Save to confirm them. Later runs perform the saved cleanup automatically.

7. Test the workflow

With Enabled checked, click Run for a manual test. Deep Research can take several minutes. Select the run in Runs and check that research, report, and cleanup finish successfully. Open ExtendLM’s Artifacts page to find the report. If necessary, fetch artifacts from all notebooks and search for your notebook or report title. Check that the imported sources were removed.

Manage Artifacts

Research or generation is unavailable: check your NotebookLM account’s access and usage limits. A stopped or failed run does not necessarily produce a report; inspect its result before running again.

Deleting sources is permanent and can prevent reopening the report’s underlying source material or following its citations. Remove the cleanup step if you want to keep that material.

Notebooks collect duplicate sources over time: the same web page added twice, a PDF uploaded again, or a copy of a text with small edits. Dedupe finds duplicate sources in a Gemini Notebook (NotebookLM) notebook and removes them, keeping one copy of each. It can find exact copies and, if you want, near-duplicates whose content is only slightly different.

Open Dedupe

From the dashboard

Locate the extension icon next to the address bar in your browser. If it's not visible, click the browser's extensions icon to reveal it. Click on the ExtendLM icon to open the popup, then click Manage Notebooks. On the Notebooks page, expand a notebook with the arrow on the left and click Dedupe in its toolbar.

From Gemini Notebook

In the notebook, open the Sources menu at the top of the Sources panel and click Dedupe.

Choose how to compare

The Dedupe Sources dialog compares all ready sources in the notebook. Choose the options and click Start dedupe:

• Ignore hosted image URLs when comparing sources (on by default): Gemini Notebook stores image links inside a source's text, and they differ between copies. Ignoring them lets two copies of the same page or PDF match.
• Find near-duplicates (not just exact matches): also treats sources with very similar content as duplicates. Set Minimum similarity between 50% and 100% (85% by default). Lower values find more matches, but also more sources that only look alike.
• Review duplicates before deleting: only scans and then lets you choose what to delete. Without it, duplicates are deleted right away.

Sources match when they have the same URL, are the same YouTube video or the same Google Drive file, have the same content, or, with near-duplicates on, have similar content. In each group the first source added is kept as the original.

Dedupe runs as a background job, so you can keep working. Only one dedupe can run for a notebook at a time.

Review the duplicates

With Review duplicates before deleting on, Review Duplicate Sources opens when the scan is done. Each original is shown with its duplicates and the reason they match, for example Same URL, Same content or 76% similar content. Duplicates are selected for deletion and originals are kept.

• Uncheck a duplicate to keep it, or check an original to delete it instead.
• Select duplicates restores the suggested selection, and Deselect all clears it.
• Each group must keep at least one source. If every copy in a group is selected, the group is highlighted and you cannot continue until you deselect one.

Click Delete selected and confirm. The sources are deleted in the background and you are notified when it is done.

Good to know

• Deleted sources are removed from the notebook permanently. To keep a copy first, export the sources or save them to the Library.
• Only ready sources are compared; sources that are still processing or failed are skipped.
• ExtendLM also skips duplicate links when you add sources, so duplicates are less likely in the first place.

Move or copy sources · Export / Import sources · Manage Notebooks

ExtendLM adds keyboard shortcuts for Gemini Notebook (NotebookLM): add the page you are reading to a notebook, save it as a PDF to your Library, send selected text or several tabs at once, open notebooks and ExtendLM pages, create a notebook, or open Generate Artifacts - all without opening the popup first.

The shortcuts are browser keyboard commands, so they work from any web page, not only from NotebookLM. No keys are assigned by default. You choose the key combinations for the actions you use most in your browser's shortcut settings.

Set your shortcuts

To open the keyboard shortcut settings, locate the extension icon next to the address bar in your browser. If it's not visible, click the browser's extensions icon to reveal it. Click on the ExtendLM icon to open the popup, then click Keyboard Shortcuts below Folders.

You can also open them from:

• The ExtendLM dashboard: open the profile menu in the top-right corner and click Keyboard shortcuts.
• Settings in the dashboard: the Keyboard shortcuts card lists every action with its current key. Click Change shortcuts.
• In Chrome you can also type chrome://extensions/shortcuts into the address bar.

On the browser's shortcut page, find NotebookLM Extension (Gemini Notebook) - ExtendLM:

1. Click the pencil next to the action you want.
2. Press the key combination, for example Alt+Shift+S (on a Mac, Option+Shift+S or Command+Shift+S).
3. Leave the scope set to In Chrome.
4. Repeat for other actions. Clear a key with the X button.

The browser accepts combinations that start with Ctrl or Alt (or Command on a Mac) and refuses keys it reserves for itself, such as Ctrl+T or Ctrl+W, and keys another extension already uses. Chrome also lists Activate the extension for every extension; it simply opens the ExtendLM popup. In Firefox, the same list is under about:addons > the gear menu > Manage Extension Shortcuts.

How the shortcuts add to a notebook

Shortcuts that add something use your saved notebook: the notebook last selected in the ExtendLM popup or in an Add to NotebookLM window, together with the Google account selected there.

• Direct actions add to the saved notebook right away. A message on the page confirms Sent to NotebookLM; the source is added in the background, and a second message appears only if it fails.
• (open dialog) actions open the Add to NotebookLM window first, where you can pick another notebook or account, create a notebook, change the title, and add source tags.
• If no notebook is saved yet, a direct action opens the window instead, so you can choose one.
• On browser pages such as chrome:// pages and the Chrome Web Store, the shortcuts do nothing. Page actions also do nothing on NotebookLM itself, while selected text, screenshots, and prompts still work there.

Add the current page

• Add page to NotebookLM (detects the page type, like the popup): the shortcut version of the popup's Add to NotebookLM button. It recognizes ChatGPT, Claude, Gemini, Perplexity and Grok chats, Reddit and X (Twitter) threads, Google Drive files, image and audio files, and YouTube videos, and adds each in the right way. Any other page uses the source type you last chose in the popup (PDF, HTML or URL). If no notebook is saved, the popup opens.
• Add Page (URL) to NotebookLM: adds the page address. NotebookLM fetches the page itself; YouTube videos are added as YouTube sources.
• Add Page (HTML) to NotebookLM: sends the page content as text, which also works for pages NotebookLM cannot open by URL.
• Add Page (as PDF) to NotebookLM: prints the page to a PDF and uploads it. Useful for pages behind a login.
• Download page as PDF: prints the page to a PDF and saves it to your computer.
• Add screenshot of visible page to NotebookLM: captures what is visible in the tab and adds it as an image source.

Each Add Page and screenshot action also has an (open dialog) version.

When the add-page shortcut reads a Reddit or X thread, your browser must be signed in to that site. If the thread cannot be read, a message asks you to sign in and try again. Grok chats need ExtendLM to be allowed to access grok.com; allow it once from the popup.

Save PDFs to your Library

Three PDF actions decide whether a copy also goes to your ExtendLM Library:

• Add Page (as PDF) to NotebookLM and save to Library: always adds the PDF to the notebook and saves the same PDF to the Library.
• Add Page (as PDF) to NotebookLM, and to Library if enabled in the popup: saves the Library copy only when Save to Library is turned on in the popup.
• Save Page (as PDF) to Library: saves the PDF to the Library only, without adding it to a notebook.

Library copies use the folder and tags chosen in the popup's Save to Library settings (the gear next to the checkbox). The plain Add Page (as PDF) to NotebookLM action never saves to the Library, and the (open dialog) version shows a Save to Library checkbox.

Selected text and prompts

• Add selected text to NotebookLM: adds the text you selected as a source titled Text from the page title. When Include page URL when adding selected text to NotebookLM is on in Settings, the page address is added on the first line.
• Save selected text to Library as a note: saves the selection as a Markdown note in your Library.
• Add selected text to Prompts: saves the selection as a new prompt. The (open dialog) version opens the prompt editor so you can edit it first.

If nothing is selected, a message asks you to select some text first. See Prompts Manager for using saved prompts.

Add several tabs at once

• Add selected tabs (URLs) to NotebookLM: adds every tab you highlighted in the current window. Hold Ctrl (Command on a Mac) or Shift and click tabs to highlight them.
• Add all tabs in this window (URLs) to NotebookLM: adds every tab in the current window.

Up to 50 tabs are sent per shortcut. Browser pages and NotebookLM tabs are skipped, and YouTube tabs are added as YouTube sources. The (open dialog) versions list the tabs before you add them.

Open and create notebooks

• Open NotebookLM: switches to an open NotebookLM tab for your account, or opens NotebookLM.
• Open last used notebook: opens your saved notebook, or switches to it if it is already open.
• Find and open a notebook: opens a small window where you search your notebooks and open one.
• Create a new notebook: opens a small window: type a title and click Create. The new notebook opens and becomes your saved notebook, so the next add shortcut uses it.

Generate artifacts

Generate artifacts for a notebook opens Generate Artifacts in its own window, with the same artifact types, options and prompts as the Generate button in the NotebookLM Studio panel. Press it while a notebook is open in NotebookLM to use that notebook and account. Otherwise it uses your saved notebook, or asks you to pick one.

Open ExtendLM pages

These shortcuts open a page of the ExtendLM dashboard, reusing the dashboard tab when one is already open: Notebooks, Sources, Artifacts, Audio Overviews, Playlists & RSS, Add sources, Library, Tags, Folders, Prompts, Community and Settings.

Troubleshooting

• Nothing happens: check that a key is assigned on the browser's shortcut page and that you are not on a browser page (chrome://, the Chrome Web Store) or, for page actions, on NotebookLM itself.
• A key cannot be saved: the browser or another extension already uses it. Try a combination with Alt+Shift or Ctrl+Shift.
• The window opens instead of adding directly: no notebook is saved yet. Choose one in the window or in the popup; later shortcuts use it.
• It added to the wrong notebook: the shortcuts use the notebook and account last selected in the popup or Add to NotebookLM window. Select the right one there, or use an (open dialog) shortcut.
• An add failed: make sure you are signed in to Gemini Notebook in this browser and that the notebook has room for another source.

New to ExtendLM? Start with Quick Start. Importing chats and threads: ChatGPT, Claude, Gemini, Perplexity, Reddit and X (Twitter). YouTube: YouTube import. Artifacts: Manage Artifacts. Library: Library overview.

The Library is your personal storage for Gemini Notebook (NotebookLM) work: PDFs and other files, notes, snapshots of notebook sources, saved artifacts and notebook exports. Keep material you use often in one place and add it to any notebook later.

Everything in the Library is stored locally in this browser. Nothing is uploaded to a server, so uninstalling the extension or clearing the browser's site data removes the Library. If the browser cannot enable persistent storage, the upload area shows a warning that it may remove Library files when it runs out of space.

Open the Library

To open the Library, locate the extension icon next to the address bar in your browser. If it's not visible, click the browser's extensions icon to reveal it. Click on the ExtendLM icon to open the popup, then click Manage Notebooks. In the dashboard, click Library in the sidebar.

Locations

The Locations panel groups Library items by what they are:

• All files: everything that is not in Trash.
• Notes: Markdown and text notes.
• Sources: files and source snapshots you can add to a notebook as sources.
• Notebooks: notebook exports created with ExtendLM.
• Artifacts: saved Studio outputs such as reports, quizzes, audio and slide decks.
• Files: other files.
• Trash: deleted items, which can be restored until they are deleted permanently.

Below the locations, Folders shows your own folder tree. See Organize the Library.

Find and view files

• Search by file name, filter by tag or file type, and sort by update date or name.
• Switch between grid and list view, and choose whether folders are shown first.
• Use Multi-select to act on many files at once: move, set tags, change category, move to Trash, save as sources or notes, or Download ZIP (up to 2 GB per ZIP).

ExtendLM exports the chat of a Gemini Notebook (NotebookLM) notebook, including the notebook summary and every question and answer, to PDF, Word (.docx) or Markdown. You can add source citations in a numbered or academic style (APA, MLA, Chicago or BibTeX), and you can edit the chat before exporting: choose questions, change the text and set the page layout.

• PDF: a formatted document ready to print or share, with tables, formulas and citations.
• Word (.docx): an editable document; math formulas become Word equations.
• Markdown: plain text with formatting marks, for note apps and other tools; formulas keep their LaTeX source.

Export from the popup

Open the notebook in Gemini Notebook. Then locate the extension icon next to the address bar in your browser. If it's not visible, click the browser's extensions icon to reveal it. Click on the ExtendLM icon to open the popup.

1. Choose a format in Export as: PDF, Markdown or Word (.docx). ExtendLM remembers your choice.
2. For PDF and Word, click the page button next to it to switch between portrait and landscape.
3. Click Export chat as …. The file is downloaded.

Export from the notebook

In the notebook, click Export in the toolbar above the Studio panel and open Chat. Pick PDF, Word or Markdown to export right away, or Edit chat before export to open the editor.

Citations and citation styles

Click the gear button next to Export chat in the popup to open Chat export settings. Turn on Include citations and choose a Citation style. The setting is used for every chat export from the popup and the Export menu.

• Numbered (NotebookLM): keeps Gemini Notebook's numbers such as [1] or [2, 4] in the text and adds a Citations list at the end. It is grouped by question and shows each source with its link and the quoted passage.
• APA: in-text citations like (Source title, n.d.) and a References list.
• MLA: in-text citations like (Source title) and a Works Cited list.
• Chicago (author-date): in-text citations like (Source title n.d.) and a References list.
• BibTeX: keeps the numbered citations and also downloads a .bib file with every cited source, for reference managers such as Zotero or JabRef.

In APA, MLA and Chicago, each cited source is listed once, sorted by title, with its link when the source has one. These styles use only the source details available in Gemini Notebook, so entries show the source title and link, and n.d. (no date) where a publication date would go.

Edit the chat before export

Click Edit chat before export in the popup (above the export buttons) or in the Export menu. The editor opens on top of the notebook with the whole chat.

Choose the questions

The Questions list shows every question in the chat and how many are selected. Uncheck a question to leave it and its answer out, use Search to find one, or click Deselect all / Select all. Below the editor, Exclude questions keeps only the answers. Changing the selection rebuilds the text; if you already edited it, you are asked before your edits are replaced.

Edit the text

• Use the toolbar for headings, bold, italic, links, code, bulleted and numbered lists, quotes, code blocks and dividers, with undo and redo.
• Click Markdown editing to edit the raw Markdown, and Rich text editing to go back. The character count is shown on the right.
• Questions written as bold quotes keep their chat styling in PDF and Word, and citations like [1] keep theirs in PDF.

Citations in the editor

Include citations and Citation style are also at the bottom of the editor. They start with your popup setting, and you can see the citations in the text before exporting. With Numbered, the text shows [1]-style numbers and ends with the Citations list.

Page layout and preview

Set Font size, Line height and Margin with the − and + buttons, and switch between portrait and landscape with the page button next to Format. Click Preview to see the result as it will be exported, and Edit to continue editing.

Export

Choose PDF, Markdown or DOCX in Format and click Export. Reset to original brings back the chat as it is saved in Gemini Notebook. If you close the editor with edits that were not exported, you are asked before they are discarded.

Math formulas (LaTeX)

Formulas written in LaTeX, inline like $E = mc^2$ or on their own line like $$\frac{a}{b}$$, are supported everywhere: PDF typesets them (including chemistry notation such as \ce{H2O}), Word turns them into editable Word equations, Markdown keeps the LaTeX source, and the editor shows them as formulas.

Tips

• If nothing is exported, the notebook has no chat or summary yet.
• Long chats with citations can take a few seconds to prepare, because the quoted passages are collected from the sources.

Open the quiz exporter

• From the notebook: In the notebook, click Export in the toolbar above the Studio panel, then Quiz. If a quiz is open in the Studio panel, it is already selected.
• From the popup: locate the extension icon next to the address bar in your browser. If it's not visible, click the browser's extensions icon to reveal it. Click on the ExtendLM icon to open the popup, then click Export quiz.

If the notebook has several quizzes, pick one in the list at the top.

Formats

• Documents: PDF (printable worksheet), DOCX, PPTX and Markdown.
• Interactive: an HTML quiz, a gamified Fun quiz with a timer, or the original NotebookLM quiz page.
• Quiz & flashcard apps: Kahoot, Quizizz (Wayground), Quizlet, Anki and Google Forms (via Sheets).
• Learning platforms (LMS): Moodle XML, GIFT, Aiken, QTI (Canvas / Blackboard) and Socrative.
• Data: CSV and JSON.

Click a format to see its options and short import steps for that app. Depending on the format you can include the answer key, hints and explanations, shuffle the answer order, or set the time per question. Click Download, or Copy for text formats such as Quizlet, GIFT and Aiken.

Edit questions

Open the Questions tab to choose which questions are exported, change their order with the arrows, edit them inline or in a dialog, and add new questions. The NotebookLM HTML format downloads the original quiz page, so these changes are not included in it.

Import tips

• Kahoot allows up to 4 answers per question: choose Add question → Import spreadsheet.
• Anki: File → Import and select the file.
• Moodle: open the question bank, choose Import and pick the matching format.
• Canvas: Settings → Import course content → QTI .zip file.

Math formulas (LaTeX)

Quizzes on math, science or finance often contain LaTeX. The PDF worksheet typesets formulas such as fractions, roots and exponents (in Chrome; Firefox prints them as text), and Markdown and JSON keep the original LaTeX. The other formats (DOCX, PPTX, HTML, quiz apps and learning platforms) cannot show LaTeX, so simple formulas such as $19 \%$ or $40 \times$ are converted to readable text (19 %, 40 ×).

Export chat · Export quizzes · Manage artifacts

ExtendLM lets you tag notebooks, sources, artifacts (Studio outputs) and notes in Gemini Notebook (NotebookLM). The Tags page brings all four kinds of tags together, so you can create, edit, import, export and clean up tags, and see right away what each tag is used on.

To open the Tags page, locate the extension icon next to the address bar in your browser. If it's not visible, click the browser's extensions icon to reveal it. Click on the ExtendLM icon to open the popup, then click Manage Notebooks. In the dashboard, click Tags in the sidebar.

Four tabs, one layout

Pick a tab at the top: Notebook tags, Source tags, Artifact tags or Note Tags. Each tab has the same layout:

• On the left, the tag list: the number of tags, Create, Import CSV, Export CSV, a search box and every tag with its description, edit and delete buttons.
• On the right, the items of that kind: notebooks, sources, artifacts or notes, with all the usual actions of those pages.

See what a tag is used on

Check one or more tags in the list. The selected tags appear as chips at the top of the page, and the right side shows only the items that have any of the selected tags. Remove a chip, or click Clear in the list, to show all items again.

You can also add or remove tags on the items right there: click + Tags on an item, or the × on one of its tag chips.

Good to know

• Search matches the tag name, emoji and description.
• Each kind of tag is separate: a notebook tag cannot be put on a source. To reuse a set of tags for another kind, export it as CSV and import it on the other tab; see Import and export tags.
• Library files have their own tags, managed in the Library; see Folders, tags and Trash.

Tags page · Import and export tags

Each tab of the Tags page can export its tags to a CSV file and import tags from one. Use it to back up your tags, copy a set of tags to another kind of item, or create many tags at once from a spreadsheet or Notion.

Export tags

Open the tab you want and click Export CSV. The file is downloaded with one row per tag and the columns name, emoji, color and description.

Exporting saves the tags only, not which items they are on.

Import tags

1. Open the tab for the kind of tag you want to create and click Import CSV.
2. Choose a CSV file. A Preview shows every row and what will happen to it.
3. Optionally turn on Update existing tags when CSV values are provided.
4. Click Import. A message shows how many tags were created, updated, skipped or failed.

Supported files

• A plain list: tag names separated by commas, for example Research, To read, Q4 review.
• A tag table with the columns name, emoji, color and description, the same format as an export. Only name is required.
• A Notion export: a table with a Tags, Labels or Category column. If there are several, pick one in Tag column.

What the statuses mean

• Create: a new tag will be created.
• Already exists: a tag with this name exists and is skipped. Names are matched ignoring upper and lower case.
• Update existing: with the update option on, the existing tag gets the emoji, color and description from the file.
• Duplicate in file: the name appears earlier in the file and is skipped.
• Error: the row has no name. Fix it before importing.

Tip

To use the same tags for notebooks and sources, export them on Notebook tags and import the file on Source tags.

ExtendLM MCP lets compatible AI clients work with Gemini Notebook (NotebookLM) through the ExtendLM browser extension. After you authorize a trusted client, you can use natural-language requests to find notebooks, inspect sources, ask notebook questions, manage supported content, generate studio artifacts, run research, and export results.

Requirements

All of the following must be available while you use Gemini Notebook (NotebookLM) tools:

• The ExtendLM browser extension is installed in a supported browser.
• The browser is running.
• You are signed in to ExtendLM and Gemini Notebook (NotebookLM) in the same browser profile.
• MCP is enabled in ExtendLM settings.
• Extension connection shows Connected.
• Your AI client supports remote HTTP MCP servers and OAuth authorization.

Enable MCP in ExtendLM

1. To open the Notebooks Management dashboard, locate the extension icon next to the address bar in your browser. If it's not visible, click the browser's extensions icon to reveal it. Click the ExtendLM icon to open the popup, then click Manage Notebooks.
2. Open MCP Settings page by clicking on the profile icon located top right, and then on Settings. In the settings page scroll down to the MCP section.
3. Turn on Enable MCP.
4. Confirm that Extension connection shows Connected. If it is disconnected, keep the browser open, confirm both logins, and reload the page.

Copy the MCP server URL

In Connect an MCP client, copy the MCP server URL:

https://mcp.extendlm.com/mcp

Clients that support automatic OAuth setup need only this URL. Use Add custom client only if a client explicitly asks for a client ID and callback URL. ExtendLM MCP clients are public PKCE clients, so leave any optional client-secret field empty.

Connect a compatible AI agent

For step-by-step setup instructions, see Use Claude with Gemini Notebook (NotebookLM) or Use ChatGPT with Gemini Notebook (NotebookLM).

For VS Code, Gemini, MCP Inspector, and other compatible clients, add a remote HTTP MCP server and use https://mcp.extendlm.com/mcp. Allow the client to open the browser-based OAuth flow. Create a custom public client ID in ExtendLM only when the client cannot register automatically and provides an exact callback URL.

Review and approve permissions

ExtendLM follows least-privilege authorization. A client receives only the permissions shown on the approval page. The first connection may request a small set of permissions, and a later tool can request additional authorization when it needs another capability.

• Read permissions can cover notebooks, sources, notes, chats, labels, sharing information, artifacts, research, and tasks.
• Modify permissions can cover notebooks, sources, notes, chats, labels, sharing, artifacts, research, tasks, and account settings.
• Export permissions allow a client to create and download supported exports.

Review every requested permission before approving it. A permission upgrade must be approved with the same ExtendLM account that authorized the original MCP connection. If a different account is signed in, switch back to the original account or create a separate MCP connection.

Test the connection

After setup, start with a read-only request:

• Check my ExtendLM connection and list my Gemini Notebook notebooks.
• Show the Gemini Notebook accounts available to this connection.
• List the sources in my Market Research notebook.

The agent should check the extension connection and use the exact NotebookLM account selection returned by ExtendLM. Account index 0 is valid; clients should never guess another account index.

Example requests

You can talk to the connected AI agent naturally. For example:

• Show my notebooks updated this week.
• Summarize the sources in my Product Research notebook.
• Compare the conclusions in the 2024 and 2025 annual reports.
• Ask my Customer Research notebook what users mention most often and include citations.
• Set the chat response length in my Project Research notebook to shorter.
• Generate an audio overview from the selected sources.
• Start deep research on this topic and tell me when it is complete.
• Export the latest slide deck as PPTX and give me a download link.

Read-only requests generally need fewer permissions. Requests that change notebook chat settings, delete a chat, generate an artifact, run research, or export content may trigger an additional authorization step.

Keep long-running operations available

Generated artifacts, research tasks, and temporary exports may need the browser and extension connection to remain available. Export download links and MCP resources can expire, so save completed files promptly. Depending on format and size, an export may be returned inline or as a downloadable resource link.

Manage or revoke access

Return to ExtendLM Settings → MCP to review authorized clients and their approved permissions. You can revoke one client, revoke all clients, or disable MCP. Disabling MCP immediately revokes every authorized client; you can enable it again later.

The optional Share NotebookLM account emails setting controls whether clients can see account email addresses. Account indexes remain available even when email sharing is disabled.

Troubleshooting

• Tools are visible but calls fail: Open the browser and ExtendLM extension, confirm both logins, enable MCP, and check that the extension connection is Connected.
• The client requests authorization again: The selected tool may need an additional permission. Open the authorization link, review the new grant, and retry after approval.
• The authorization page shows an account mismatch: Sign in with the ExtendLM account originally used for that client, or cancel and create a new connection.
• The wrong NotebookLM account is used: Ask the client to list available NotebookLM accounts and select the advertised account index. Do not invent an index.
• A download link expired: Request a new export or resource link and save it promptly.
• A client remains disconnected: Revoke it in ExtendLM MCP settings, remove the server from the AI client, and connect it again.

ExtendLM MCP is built with privacy and security in mind: Gemini Notebook (NotebookLM) content that passes through the MCP server is not stored there and is relayed directly to the MCP client you authorized, within the permissions you approved.

You can connect Claude to ExtendLM through the Model Context Protocol (MCP) and use Claude to work with your Gemini Notebook (NotebookLM) notebooks. After authorization, Claude can discover the ExtendLM tools permitted by your grant and use them in response to natural-language requests.

This connection runs through the ExtendLM browser extension. Claude does not receive your browser cookies, ExtendLM password, Gemini Notebook credentials, or OAuth tokens.

Before you connect Claude

• Install the ExtendLM browser extension.
• Keep the supported browser running.
• Sign in to ExtendLM and Gemini Notebook (NotebookLM) in the same browser profile.
• Use a Claude product and account that supports remote MCP servers or custom connectors.

Enable MCP in ExtendLM

1. To open the Notebooks Management dashboard, locate the extension icon next to the address bar in your browser. If it's not visible, click the browser's extensions icon to reveal it. Click the ExtendLM icon to open the popup, then click Manage Notebooks.
2. Open MCP Settings page by clicking on the profile icon located top right, and then on Settings. In the settings page scroll down to the MCP section.
3. Turn on Enable MCP.
4. Confirm that Extension connection shows Connected. If it is disconnected, keep the browser open, confirm both logins, and reload the page.

Add ExtendLM as a custom connector

Custom connectors are available in Claude and Claude Desktop. Availability and administration depend on your plan: free accounts are currently limited to one custom connector, and Team or Enterprise plans require an Owner to add the connector to the organization first.

On an individual plan, you can open the custom-connector form in either of these ways:

• From settings: Open Settings → Connectors → Add → Add custom connector.
• From a chat: Select + → Connectors → Add connector → Add custom connector.

A Team or Enterprise Owner instead uses Organization settings → Connectors → Add → Custom → Web.

1. Enter ExtendLM as the name and https://mcp.extendlm.com/mcp as the remote MCP server URL.
2. Select Add, then Connect, and complete the ExtendLM OAuth approval in your browser.

Claude Help Center: Custom connectors

Authorize Claude

Sign in to the same ExtendLM account that enabled MCP. Review the permissions Claude requests and approve only the access you want to grant. A later request can trigger another authorization page if Claude uses a tool requiring an additional permission.

A permission upgrade must be approved by the same ExtendLM account that authorized the original connection. If the authorization page reports an account mismatch, switch to the original account or create a separate connection.

Confirm the connection

Return to Claude and confirm that ExtendLM is connected.

In a chat, enable ExtendLM from + → Connectors. You can enable or disable connectors per conversation.

Your first request should be read-only:

Check my ExtendLM connection and list my Gemini Notebook notebooks.

Claude should check the extension connection, list the available NotebookLM accounts, and use an account index advertised by ExtendLM. Account index 0 is valid.

You can also view and manage the ExtendLM MCP connection under Settings → Connectors.

Connect Claude Code to ExtendLM

Run these commands in a terminal to add ExtendLM for all Claude Code projects and start the OAuth login:

claude mcp add --transport http extendlm --scope user https://mcp.extendlm.com/mcp
claude mcp login extendlm

Complete approval in your browser. Verify the connection with claude mcp list; inside Claude Code, /mcp shows the server status.
