AI Video Editor

FableCut

FableCut is an open-source browser video editor with a JSON timeline that AI agents can drive via MCP and REST APIs.

What is FableCut?

FableCut is a non-linear video editor that runs entirely in the browser, exposing its timeline as a single JSON document. It allows AI agents (via MCP or REST) and humans to edit videos collaboratively, with the UI hot-reloading changes in real time.
