Raise Your Hand

Pause a YouTube university lecture and ask a course-aware teaching assistant that knows the whole playlist.

Raise Your Hand turns any YouTube university course into an interactive class. Pause a Stanford or MIT lecture, raise your hand to your webcam (or press a shortcut), and ask your question out loud, the way you would in the room. You hear a short, spoken answer that knows exactly where you are in the course. What makes it different: • It read the whole course. It knows the syllabus and the point where you paused, and points you to the right lecture and timestamp, in the course's own terms. • It won't spoil what's next. Ask about something the course covers later and it tells you where it's coming instead of getting ahead of the professor. • Hands-free and spoken. Voice-first and spoken back, so you stay in the flow of the lecture — the closest thing to a teaching assistant sitting next to you. How it works: 1. Raise your hand to your webcam (or press a shortcut) to pause and start listening. 2. Ask your question out loud, in English or Portuguese. 3. Hear a brief answer. Say "no" and the lecture plays on. Free, no account needed. Your webcam is processed entirely on your device — its video is never uploaded. You can turn the camera, spoken answers, screenshots, or anonymous feedback off in the settings at any time. Works on YouTube course playlists. Privacy policy: https://raise-your-hand.cloud/privacy
