Capta

Record a demo of your app and every screen recorder on the market hands you the same thing back: your footage, untouched, with the pauses and the typos and the minute of fumbling left in, and a timeline in which to spend your evening fixing that. Capta hands you the edit. While you record it watches your clicks, your typing and your scrolling, and when you stop it has already chosen the zooms, cut the dead air, sped up the typing and set the pacing.

The camera work is the part you notice first. Capta reads the UI element under every click and frames it with spring-damped moves that glide rather than snap - and when an app will not say what you clicked, it finds the dialog in the pixels and frames that instead. Drop in a music track and every cut lands on the beat; no track handy, and three built-in ones or a Creative-Commons search are one click away, with a drag handle to pick exactly which stretch of the song plays.

Talk while you record and Capta transcribes you on the Mac itself, burns in captions, steers cuts and speed-ups around your sentences, and ducks the music under your voice. Flip the camera on and you appear as a floating bubble - circle, rounded or square, any corner. On a Mac with Apple Intelligence, the on-device model also picks the moment your demo builds toward, titles its chapters, and writes the video's title, caption and social post from what actually happened on screen.

All of it runs on your Mac: the recording, the edit engine, the transcription, the AI. No account, no uploads, no telemetry - the only network requests it can make are the update check and the music search, and both wait for you to click.
