Tell the agent the story. It assembles clips, captions, and voice so you start from a draft, not an empty track.
Descript is strong when you edit by deleting words from a transcript. StarCut takes a different path: you describe the video you want, an agent plans the cut with captions and voice, and you keep a full visual timeline in the browser.
Runs in the browser. No install needed.

You can ask for transcript-style cuts, but the source of truth is the timeline, not a text document.
