AudioPen turns voice notes into clean written notes. This app connects ChatGPT to the user's AudioPen library so ChatGPT can search their notes by keyword (matching titles, note text, original voice transcripts, tag names, and folder names), list the tags and folders in the library, and read a single note in full including its original transcript. Typical workflows: recall what the user said about a topic, summarise several notes on a theme, turn a note into an email or an outline, or compare the cleaned-up note with the raw transcript. Every tool is read-only. The app cannot create, edit, or delete notes, and it only sees the account the user signed in with. Requires an AudioPen Prime subscription. Sign-in uses AudioPen's own email one-time code flow through OAuth, so ChatGPT never sees the user's AudioPen credentials.
