GrepCut

A browser-based video editor that uses AI agents to help build edits from natural language descriptions. Users can upload footage to a persistent library where visuals, speech, and objects are indexed, allowing them to search for specific moments by meaning rather than scrubbing through timelines. The platform includes features such as AI object tracking, relighting, transcription, chroma key, color grading, and 4K 60fps export. It integrates with tools like Google Drive, YouTube, and TikTok, and offers built-in asset generation using models like LTX 2.5 and Gemini 4 Argon. The service is marketed as a free alternative to traditional editors, with 90% of tools available without login.

GrepCut combines a full-featured timeline editor with an AI agent that can search footage by semantic meaning and generate assets directly on the timeline, all within the browser without software installation.
