How it works

It checks before it writes

Give it a topic. It gathers the claims, finds two sources for each, and stops if a number on screen has none.

It listens to its own voice

Every line is played back to a speech model. A mumble, a long pause or a wrong word is recorded again on its own.

  • Whisper hears each line back, so captions and cuts land on the spoken word.

  • ACE-Step writes three takes at your tempo and keeps the steadiest one.

  • A canvas player draws every frame the same way each time, across several workers at once.

  • Turns a 60-second Short into a three-to-five-minute 16:9 lesson with chapters and a thumbnail.

  • Uploads to YouTube with captions, playlist and thumbnail, private or scheduled, once you say yes.
