MensorAI от Rouven

MensorAI is a browser extension that adds a note-taking sidebar to YouTube. While watching videos, you can:
- Take timestamped note: click to insert the current video time, click timestamps to jump back
- Ask AI about the video: type /ask to query the video's transcript (e.g., "What were the 3 main points?")
- Sync notes across devices: sign in to access your notes anywhere

The sidebar opens via a tab on the right side of YouTube.
