Your agent makes the demo video.
Ask Claude Code or Codex for a launch video. StageMaster scripts it, films your Mac in one take, and voices it.
How it works
Ask. Tell your agent what to show: a launch, a feature, a tutorial.
It scripts. The agent writes the lines and every click, key and scroll behind them.
Your Mac performs. StageMaster films one take while the script drives the app. Bad take? Change a line, roll again.
You cut. Trim, zoom, swap a voice line, export.
No script? Hit record, use your app, add the voice after.
Voices
54 voices built in.
They run on your Mac. No download, no account, nothing uploaded.
Have your own model? Point StageMaster at any OpenAI-compatible TTS server.
Several reads per line. Keep the best one.
Voice cloning: coming soon.
