Field notes
Diffcut’s page lays out an edit path from frame-level timeline controls through captioning, voiceover, generated music and effects, and browser capture. It says transcription, speech generation, and rendering stay on the Mac, and describes preview and export as sharing a pipeline; exported frames are reportedly checked after writing with per-frame hashes. The page also links to source under an MIT licence, while Claude-assisted editing is marked “New in the app” and additional tool integrations are marked “Coming soon.”
