Video tools: common questions

Which browser do I need?

A current one: recent Chrome, Edge, Firefox or Safari. Saving video uses WebCodecs; Video to GIF and Extract audio do not need it. If your browser lacks something, the tool tells you before you start.

Do the automatic subtitles use AI?

Yes, but on your device: Auto subtitles and Transcribe use Whisper, a speech-to-text model that downloads once and runs in your browser. It can get names or noisy parts wrong, so check the text before you use it.

Are my videos uploaded to a server?

No. The tool runs inside your browser: videos are read and processed on your device and are not sent to Cocuyo or to any third party. The libraries are served from our own site, with no external services. You can check it in your browser’s network tools: your file is not sent.

Is it really free?

Yes. You can try them before signing up; to download a result or keep using them, we ask for a free account, with no subscription. Your free account comes with 30 welcome uses; after that, each use costs 1 credit (top-ups from US$1), and they are unlimited with Basic or Pro. They never add a watermark.

What are the limits?

In general, videos up to 300 MB and 10 minutes that your browser can play (MP4, WebM or MOV), with output up to 1080p. Some tools have their own limits, such as the free transcription in Auto subtitles, up to 3 minutes; each page says so.
