FableCut

FableCut is a local video editor for people who want to make cuts themselves and work alongside an AI agent. Both can edit the same project, with agent changes appearing live in the browser.

• Shared agent-editable timeline. The project stores clips, tracks, effects and transitions in one JSON file, so agents can arrange footage, add titles and adjust edits through MCP or REST.
• Multitrack editing. Trim, split and snap video and audio clips, undo changes, and link or separate a video's audio; track and clip locks protect sections while you edit elsewhere.
• Titles, effects and motion. Add text, animated SVG overlays, filter presets and keyframes, or move, resize and rotate clips and titles directly in the preview.

FableCut runs on your machine using Node.js and a Chromium-based browser. Projects and footage live locally. Its agent interface works with compatible clients such as Claude Code, Claude Desktop and OpenCode; where the AI runs depends on the client and model provider you choose.

It's open source under the MIT license. Export runs in the browser, with optional ffmpeg for faster export or direct rendering. Browser export requires a user click. AI background removal needs an internet connection to download its model from a CDN on first use.
