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 HubTwo extensions we build and maintain.
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.
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.
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.
Conversational Bot (Versatile Bot Project)
Shun Tsukamoto
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.
Custom Bot (Versatile Bot Project)
Shun Tsukamoto
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.
Listener Bot (Versatile Bot Project)
Shun Tsukamoto
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.
Chat Episode (Versatile Bot Project)
Shun Tsukamoto
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.
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.
NotebookLM MCP Server (PleasePrompto)
open-source project
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.
NotebookLM REST API + MCP Server (roomi-fields)
open-source project
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.
