MirrorCut is an AI video editor that converts raw recordings into polished video ads, Shorts, and Reels through an agentic editing workflow. Users upload footage, describe the desired edit via prompt or chat, and the AI agent handles dead air removal, filler word cutting, captions, reframing, and motion graphics. Every AI-generated change is surfaced on a real timeline with Accept and Revert controls, keeping the creator in full control of the final output. MirrorCut supports multiple aspect ratios including 16:9, 9:16, 1:1, and 4:5, and plans to export Premiere Pro XML and After Effects files for further editing.
