CapFlow: Auto Captions AI App

Add auto captions and subtitles to your videos in a few taps. CapFlow is a captions app and subtitle generator: it listens to the speech in your video and writes word-timed captions you can edit, style and burn into the video, or save as a subtitle file. No watermark.

Made for talking videos: Reels, TikTok and YouTube Shorts creators, podcasters, teachers, coaches and anyone who wants their video understood with the sound off.

HOW IT WORKS
1. Pick a video, or share one to CapFlow
2. CapFlow detects the spoken language and writes the captions
3. Fix any word and choose a caption style
4. Export the captioned video, or an SRT or VTT file
