Everything your video needs, in one tab

Cut your clips, caption them and export in the format each platform wants. The whole editor loads in the browser you already use.

Auto captions that run on your device

Whisper turns speech into word-by-word captions inside the browser. Your audio never goes to a server, and you pick a faster or a more accurate model.

FAQ

Questions creators ask first

Is Reeltab really free?

Yes. The editor is free with no watermark and no export limits. It is open source under the MIT license, so the code will stay public.

Why do you ask for my email?

Your email unlocks the editor and lets us tell you when new features ship. We don't sell it, and you can ask us to delete it at any time.

Do my videos get uploaded anywhere?

No. Footage is loaded from your computer and kept in your browser's storage. Captions are generated on your device as well.

Can I add subtitles to a long lecture?

Yes. Import the recording, open Captions and pick a model. For long videos use the Small model in Chrome or Edge: everything runs on your computer, so an hour of audio takes a while to transcribe.

Which browser should I use?

A recent version of Chrome, Edge, Arc or Brave works best. The largest caption model runs best with WebGPU, which these browsers support.

How is this related to OpenCut?

Reeltab is a redesigned fork of OpenCut, an open-source video editor released under the MIT license. Credit for the editor engine goes to the OpenCut team.
