A hands-free teaching assistant for YouTube university courses. Pause a Stanford or MIT lecture, ask out loud, and hear a short answer that knows exactly where you are.
DPO is a simpler alternative to RLHF — but you haven't reached it yet. The professor derives it later in this same lecture, around 1:32:43, right after PPO.
A small wave to your webcam pauses the video and starts listening. A keyboard shortcut does the same, if you prefer.
Say your question the way you would in class. It works in English and Portuguese, and understands messy, real speech.
A brief, spoken answer, grounded in this course and its own notation. Say "no" and the lecture plays on.
It knows the syllabus and the exact point where you paused. Answers point you to the right lecture and timestamp, in the course's own terms.
Ask about something the course covers later and it tells you where it's coming instead of getting ahead of the professor. Learn in order.
Voice-first and spoken back, so you stay in the flow of the lecture. It's the closest thing to a teaching assistant sitting next to you.
Anyone can watch a Stanford or MIT course on YouTube. Almost no one has someone to ask.
Raise Your Hand is a small, free project to give self-learners everywhere something closer to being in the room: a hand to raise, a question to ask, and an answer that actually knows the course.
