How it works

01Add sources

Upload files or recordings, paste a link, or paste text. Each source is split into passages and indexed for search by meaning, not just keywords.

02Ask anything

Answers come only from your sources, with a numbered citation on every line. Click one to jump to the exact passage it came from.

03Make things

Turn sources into summaries, key insights and quotes, or the whole notebook into a briefing doc, study guide, FAQ, timeline, mind map or action plan.

04Listen

An audio overview: a deep-dive conversation, a debate, an interview or a quick brief, voiced and downloadable as an MP3.

Where your notebooks live. Sources, notes, chats and audio are saved in this browser only, not on our servers and not in an account. To answer you, only the passages a question needs are sent to the AI, and Cocoon does not store them. Clearing your browser data deletes your notebooks, so use Export to keep a copy or move to another device.
