CUTROOM edits video entirely on your machine using WebCodecs and private browser storage. Right now those are only solid in Chrome and Edge on desktop.

Nothing is uploaded anywhere in any browser — that's the whole point.

Chapters

Split the video into segments by topic, from the transcript. The local engine runs on this computer (downloads a ~25 MB model once).

⚠ This sends the transcript text — never audio or video — to Anthropic's API using your own key, at your own (tiny) cost. Skip it and everything stays on this computer.
