It listens for your cue — then reads back

Run the scene.
Any hour. Any line.

Upload your sides, cast the room, and rehearse with an AI scene partner that hears you land your line, waits for the cue, and answers in a voice you design. When you're off-book, roll a self-tape without ever leaving the scene.

Voice design

Describe the voice. The AI casts it.

“A warm male voice, late 40s, faint Irish lilt — low, unhurried, a little weary.” Type what you hear and your scene partner speaks in it. Or let the AI cast it for you, or pull from voices you've saved.

  • Describe age, gender, accent & tone
  • Auto-cast or reuse saved voices
  • A distinct voice per character

The rehearsal

It listens. It waits for your cue.

The Reader follows along as you speak — on device — so it knows the moment you finish your line, then answers right on cue. Fumble a word and it holds; nail it and it moves. It's the closest thing to a real reader who never gets tired.

  • Speech following that waits for your last word
  • Hands-free — pause, resume, jump lines by voice or key
  • Focus mode: one line at a time

  • Your line and the cue on screen together
  • Scene partner plays live as you tape
