About this app

Add auto captions and subtitles to your videos in a few taps. CapFlow hears every word, writes it on screen and lets you style it, so people keep watching, even with the sound off.

Fix any word, pick a look, then share your captioned video or save a subtitle file. CapFlow is a simple, free captions app for creators, teachers, coaches, podcasters and anyone who talks on camera.

No editing skills needed. The app does the slow part for you, and you stay in control of every word, every line and every look. Your next post can be ready before your coffee gets cold.

HOW IT WORKS
1. Pick a video from your gallery, or share one from another app
2. Wait a moment while the words appear on screen
3. Fix anything you like and choose a style
4. Save the finished video, or a file to upload with it
