Make subtitles for your videos with AI

How to generate automatic captions for your videos (for example on YouTube), review and translate them, and why good captions make your content accessible.

By Cognenza editorial team · Updated · 2 min read · Sources cited

Many people watch videos muted, and others can’t hear. Captions aren’t an extra: they’re how everyone understands you.

  1. Generate: YouTube creates automatic captions; review and edit them in YouTube Studio. Or start from a transcript.
  2. Review proper names, numbers, acronyms and jargon.
  3. Adjust: short lines, good sync.
  4. Translate with AI and check it.

Make it accessible

The W3C explains captions should also include relevant sounds and identify speakers. More in AI and accessibility.

Frequently asked questions

Does YouTube generate captions on its own?

Yes, YouTube offers automatic captions using speech recognition in several languages. Its help warns they may contain errors and creators can review and edit them.

Why review if they’re automatic?

Because for someone who can’t hear, one error changes the message. The W3C recommends accurate, synchronised captions as part of accessibility.
