Diffcut and Descript, side by side.

Descript edits video by editing its transcript, with collaboration and recording built in. Diffcut is a timeline editor for the Mac, open source, that transcribes and makes voices and music on your machine.

Diffcut is in early development: the first Mac build isn’t out yet. Descript details are general, from public information as of October 2026; check www.descript.com for current plans and features.

Questions

Can Diffcut edit video by editing text?

Not the way Descript does. Diffcut transcribes every word on your Mac for captions, and your own Claude can find pauses and fillers and propose cuts for you to review, but editing happens on the timeline.

Does Diffcut need an internet connection?

Not to edit, transcribe, make voices or music, or export. Asking Claude uses your own Claude Code, which does.

Can I clone my own voice in Diffcut?

No. Diffcut has 28 stock English voices, and every take carries a watermark.
