Tools

Tools that extend Gemini Notebook

Import in bulk, organize notebooks, and generate better prompts. Community-built tools link to where their authors shared them, so credit lands in the right place.

Our Chrome extensions

From the Hub

Two extensions we build and maintain.

Mind map editorEdit the mind maps NotebookLM can only generate — rearrange, recolour, export to SVG and PNG. Free, in your browser.

YouTube to NotebookLM

browser extension

Send entire channels, playlists or search results into a notebook in one click instead of pasting videos one at a time.

Importfreemium

Folders for NotebookLM

community project

Adds folder organization to the notebook list — built by a community developer who got tired of waiting for the official feature.

EPUB to TXT converter

community project

Converts ebooks into clean plain text for upload — still useful for EPUBs that import poorly.

Academic Prompt Lab

community project

A prompt generator covering twenty analysis types — gap analysis, thematic coding, Feynman technique — with a rigor toggle.

Promptingfree

SurfSense

open-source project

Self-hosted Gemini Notebook alternative that connects Slack, Notion, GitHub and more — for teams whose documents can't touch a third party.

Researchfreeopen source

Makes a notebook answer in a friendly, chatty register while still handling analysis and generation requests. Spells out how it weighs your uploaded sources against general knowledge — where the two disagree, your sources win.

Promptingfree

A harness rather than a persona: it reads whatever system prompt you put in a second source and follows that. Add this document plus your own instructions and the notebook becomes that assistant; add it alone and it asks you for the instructions.

Promptingfree

Draws a half-formed idea out of you through questions, then turns the finished version into a deliverable — audio, diagram, slides or video. Runs in a default conversational mode until you explicitly ask it to export.

Promptingfree

For Audio Overviews rather than chat. Restructures the episode so the hosts pause for listener input instead of talking straight through, with rules for switching language mid-episode.

Promptingfree

Tools are listed because the community finds them genuinely useful — nobody pays for placement. Built something Gemini Notebook users would want? Share it in r/notebooklm and it will find its way here.

MCP servers

For agents and automations, not for browsing by hand — these let an AI agent drive Gemini Notebook directly over MCP instead of through the web UI.

Drives a real Chrome session so an AI agent can chat with a notebook, add sources, and generate Audio Overviews, with DOM-level citations in every response. Needs a persistent Chrome profile signed into one Google account.

Automationfreeopen source

Wraps every Studio output — audio, video, infographics, reports, slides, data tables — behind a 33-endpoint REST API, built for wiring NotebookLM into n8n, Zapier or Make. Supports multi-account rotation for batch jobs.

NotebookLM MCP (khengyun)

open-source project

Talks to NotebookLM over its internal RPC calls instead of driving a browser, so there's no Chrome process to keep alive. Around 28 tools cover chat and source management, plus source merging across notebooks and mind maps.
