AI agent that edits your videos for you

CUT3 is an agentic video editor. You describe the edit in chat and Cutie rewrites the timeline, returning every change as a diff you approve or reject before it lands. It plans the work and spawns parallel subagents for separate compositions, calling beat detection and audio-onset alignment, text-to-video and image-to-video generation, voiceover, automatic subtitles, background removal and web image search as tools rather than features you configure. Free tier available, no watermark from Pro.
