Vidnotes (published in the Chrome Web Store as Columbia Notetaker) is a free Chrome extension that generates AI-written notes from Columbia recitation recordings. When you play a recitation recording in the browser, the extension turns it into structured, timestamped notes so students can review the highlights instead of re-watching an entire session. It is intended for educational use and keeps the notes tied to the source material.

Play a Columbia recitation recording and the extension drafts AI notes from the spoken content, so you do not have to transcribe it yourself.
Notes are tied to timestamps in the recording, making it easy to jump back to the exact moment a point was made.
Notes condense a full session into the key points, so reviewing before an exam takes minutes rather than hours.
Installs as a lightweight Chrome extension that the developer states does not collect or sell user data.
