Briefcut by Aubric, Inc.

Briefcut by Aubric, Inc. A video editor where Meta's models plan, check and review the cut, your computer renders it, and every version ships with receipts you can verify. I am Ankit, founder of Aubric, Inc. I built Briefcut alone during the hackathon. The first commit was October 29. Nothing existed before it. The problem. Creators have footage and no time. The AI editors that promise to help are black boxes. You cannot see why a cut was chosen, you cannot script it, and you cannot prove the file is what you approved. What Briefcut does. Meta Voice Transcribe hears the footage, in 25 languages. Muse Spark watches it, picks the moments, and says why. SAM 3.1 follows the subject for a 9:16 reframe, cuts it out so a hero word can sit behind it, and confirms that a moment Spark found is really on screen. Muse Image paints covers and backdrops. Muse Wonder watches and listens to the finished cut like a director and returns fixes as data. Briefcut validates the fixes and renders version two. In private mode, Muse Glimmer 30B, Meta's open-weight model, runs the text steps on your own computer. FFmpeg renders locally. Your original files never leave your machine. Every version ships with receipts. Each check says how it is known: probed from the file, measured by code, or a model's opinion. The command vedit verify re-hashes the video and every record with no network call. Measured live. Tears of Steel, a 12-minute film, became a 44 s trailer and three shorts for $0.34, with 5 of 5 checks on every export. Short projects took 24 s to 2.5 minutes and cost $0.0005 to $0.08 of Meta usage each. Muse Code, Meta's own agent, ran a full edit through Briefcut's 22 MCP tools in eight tool calls and about two minutes. Who it is for. Creators with phone footage, teams that need sign-off before posting, podcasters and educators with up to 2 hours of recordings per project, and developers who need video as an API. Cents per video on your own Meta key, no subscription. The source is public to read and run.
