Everything it does with what you saved
Notebooker is a research notebook that answers out of your own sources, then builds things from them, on models and storage you choose.
Ask a question and every claim links back to the exact source you saved - plus a coverage meter showing how many of the documents it consulted actually made it into the answer.
Turn a page or a whole notebook into a podcast in the format you're in the mood for - deep dive, quick brief, frank critique, two-sided debate, or unabridged walkthrough. Subscribe with a private RSS feed in any player.
Math-aware narration turns equations into spoken English - "sigma squared over n", not "dollar backslash frac". STEM sources finally work as audio.
Flashcards with real spaced repetition (and Anki export), charts, mindmaps, infographics, even full textbooks - built from your sources in a click.
The Socratic tutor turns a notebook into a guided session - one question at a time, wrong turns met with counter-questions, hints that shrink the problem, and answers cited to your sources only after you've worked for them.
One click puts a creation on the web from your own storage, on your own domain - a full multi-page website, or a live flashcard deck, chart, or timeline as a single shareable page - with an iframe snippet to embed it in any site.
The browser extension reads your NotebookLM notebook and recreates it here - name, sources and all - since Google won't give you an export. One click, one preview, done.
Built-in personas read your sources the way you need - Professor teaches it, Critic stress-tests it, Debate argues both sides, Beginner's Guide starts from zero.
Watch any RSS feed or YouTube channel and new posts become sources automatically. Workflows and webhooks connect everything else.
Save links, write notes, search, ask cited questions, and export notebooks from scripts and automations - a documented REST API with personal keys or OAuth, at docs.notebooker.ai.
Connect Claude or any MCP client to your library over OAuth - it can search your sources, manage notebooks and notes, and answer with citations from what you've saved. No keys to paste.
OpenAI, Anthropic, or a local model - you choose what reads your notes, and you can bring your own API keys.
Point Notebooker at any S3-compatible bucket - R2, Spaces, AWS - and everything it stores lives with you. Export notes as Markdown or your whole library anytime.
Web app, iOS and Android, browser extensions, and native desktop apps - one library, always in sync.
