How a film works on heyprof
Every film here listens. Pause it, ask it questions and let it continue with your own examples.
- PauseTap pause or press the space bar. The film waits right at that moment.
- AskTap “Ask” and type what you want to know. The answer comes inside the film, with picture and voice.
- Steer itTell it what to show, for example “Do this with z = 2 − 3i”. The film sets up the app and works it out.
- Try it yourselfWhile it is paused, drag points and sliders yourself. “Continue” takes you back into the film.
Without an account: five questions per visit. With an account you can also ask by voice.
