FableCut

FableCut is a browser-based non-linear video editor that exposes its entire timeline as a JSON document for AI agents to drive.

FableCut is a Premiere-style non-linear video editor that runs entirely in your browser and exposes its whole timeline as one JSON document. It is built for humans and AI agents like Claude Code or Claude Desktop to work on the same timeline simultaneously. You can edit by hand through the user interface or let an AI agent cut your video while you watch the timeline update live via server-sent events. It features video and audio tracks, direct manipulation on the monitor, timeline multi-select, a full mixer with submix buses, audio effects, and automated tools like auto-ducking and noise reduction. The software requires zero npm dependencies and runs on a single node server.js file.
