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.
