Better than automatic YouTube captions

YouTube’s automatic captions often miss names, brands and punctuation, and you can’t style them. With HeyCaptions you get a clean transcript you can correct before publishing, and you decide whether viewers see closed captions or burned-in captions.

For long videos, upload the SRT file in YouTube Studio so viewers can switch subtitles on and off. For Shorts, burn animated word-by-word captions into the video.

Subtitles help your videos get found

A subtitle file gives YouTube the full text of your video. That helps it understand your topic – and viewers who watch with the sound off or in a second language are more likely to keep watching.

Frequently asked questions

How do I upload subtitles to YouTube?

In YouTube Studio, open the video, go to Subtitles, choose Add language, then Upload file → With timing and select the SRT file you downloaded here.

Should I burn captions into my YouTube Shorts?

Yes. Most viewers don’t turn on closed captions for Shorts, so burned-in captions are the best way to make sure everyone can read along.

Which videos can I upload?

Videos you own or have the rights to use. To caption a video already on your channel, download the original from YouTube Studio and upload it here.

Is HeyCaptions really free?

Yes, 100% free. No sign-up, no watermark and no paid “export” step.

What happens to my video?

Your file is only used to create your captions. It is processed on our own servers and permanently deleted as soon as you are done – at the latest 30 minutes after your last activity. We never use your files for anything else.

Which languages are supported?

HeyCaptions recognizes 99 spoken languages, including English, Spanish, German, French, Portuguese, Italian, Dutch, Polish, Turkish, Japanese, Korean, Chinese, Hindi and Arabic. The language is detected automatically.

Are there any limits?

Files can be up to 500 MB and 30 minutes long. MP4, MOV, WEBM, MKV, AVI, MP3, WAV, M4A and most other formats work.

Does it work on my phone?
