Why it works

Why use CutLuma for this

Word-by-word highlights

Each word lights up as it is spoken — colour, box, bounce or reveal — the style that keeps people watching.

English, Arabic, Spanish, French, Hindi, Urdu and more. Arabic and Urdu captions are laid out right-to-left correctly.

Editable, not baked

Every caption is a normal text clip. Change the wording, font, colour or position before you export.

FAQ

Questions? Answers.

Is the caption generator really free?

Yes. You can caption a few minutes of video every day without an account. A free account gives you 10 minutes every month, and paid plans give you hours.

Which languages are supported?

Seventeen, including English, Arabic, Spanish, French, German, Portuguese, Italian, Turkish, Russian, Hindi, Urdu, Indonesian, Japanese, Korean, Chinese and Dutch. The language can also be detected automatically.

Can I edit the captions?

Yes. Click any caption on the timeline to fix a word, or restyle every caption at once with one click.

Do captions help my videos perform?

Most people scroll with the sound off. Captions let them follow along, which usually means longer watch time and more reach.
