How to add bold word-by-word captions to a video

Upload your talking video (up to 90 seconds) to Auto Captions. It listens to every word, burns in bold word-by-word captions, turns the video vertical at 1080x1920, keeps 60 fps if you filmed in 60, and levels the sound. You watch a watermarked preview free, then pay $2 to download it clean. No app and no account.

Questions

Do I need to install an app?

No. It works in your browser, on a phone or a computer.

What if the preview isn't right?

You see the result before you pay, so you never pay for a file you didn't like.

Good to know

  • Captions are burned into the video, so they show on every app.
  • 60 fps is kept if you filmed in 60 fps, and the sound is levelled.
  • Your upload is deleted as soon as the file is made, and the finished file after 48 hours.
