A playlist URL goes in, transcripts come out as cards, and the same connection runs the daily review and reports how it went — so the whole loop from source material to retained knowledge happens where you already are.
The hosted server for Acornonaut, a study tool that generates flashcards from YouTube transcripts and schedules their review using the SM-2 spaced-repetition algorithm. It runs at mcp.acornonaut.app and signs you in through the browser.
- Playlists created from a YouTube URL, listed with their status and progress, renamed, reconfigured or deleted
- Videos added by URL to an existing playlist, with the transcript retrievable and the cards generated from a video listed
- Cards created, read, edited, deleted and searched across the whole library
- The review loop itself: the cards that are due, an answer recorded against each, and the statistics that come out of it
- Semantic search across your cards, so a half-remembered concept is findable without the exact wording
- Export to Anki, so the deck is not trapped in one product
An Acornonaut account, authorized over OAuth — the browser opens on first connection and your client keeps the token. Any client that speaks streamable HTTP can connect to the hosted URL; there is nothing to install and no API key to manage.
