Your keys · Your storage · Your data
Turn what you save
into what you know.
Notebooker keeps everything you collect — and answers questions about it, reads it aloud as podcasts, and turns it into study material. Built in the open, on your own keys and storage.
From your notebook
"My saved articles disagree about caffeine and sleep — who's actually right?"
Two of your three sources agree it's the timing, not the dose: caffeine's half-life means an afternoon cutoff matters more than how much you drink. Sources: ¹ ² ³
01 — Collect
Links, PDFs, audio, video. From your browser, phone, or any app that can send a webhook.
02 — Ask
Chat with a notebook and get cited answers. Full-text search across everything you've saved.
03 — Transform
Podcasts, flashcards, mindmaps, textbooks — generated from your sources, not the internet.
What it does with what you save
No dashboards to maintain, no folders to tidy. You save; Notebooker makes it useful.
Cited answers, not vibes
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.
Your reading list, as radio
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.
Study material on demand
Flashcards with real spaced repetition (and Anki export), charts, mindmaps, infographics, even full textbooks — built from your sources in a click.
A professor, a critic, a debater
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.
Feeds that fill your library
Watch any RSS feed or YouTube channel and new posts become sources automatically. Personal API keys and workflows connect everything else.
Any model, your keys
OpenAI, Anthropic, or a local model — you choose what reads your notes, and you can bring your own API keys.
Your own storage
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.
Everywhere you are
Web app, iOS and Android, browser extensions, and native desktop apps — one library, always in sync.
Private by construction, not by promise
Most "privacy-first" claims ask you to trust a policy page. Notebooker hands you the controls instead.
