- Reported models: MLX Whisper. Tools: Electron, React, TypeScript, FFmpeg, FFprobe, REA, Ghidra. The writeup below describes the work attributed to AI.
- Reported result
- Partial. This is the directory's source-based outcome classification.
- Independent confirmation
- Not reported.
- Human work and limitations
- The project is explicitly labeled as early development. It is not a clone of CapCut but an independent implementation informed by research into the target's behavior. Windows and Linux support are currently unavailable, and the macOS builds are ad-hoc signed rather than notarized.

What was done
ReaCut is an independent, open-source video editor for macOS that uses REA-assisted research to study Jianying/CapCut interface behavior and project formats. It provides local multitrack editing, speech transcription, and export capabilities without relying on cloud services.
ReaCut is an independently implemented video editor designed for macOS, specifically targeting Apple Silicon. The project utilizes REA to research the interface behavior and local project formats of Jianying / CapCut. The author explicitly states that research is conducted within authorized scope and does not copy proprietary code or assets from the target application. ReaCut functions as a local editor using Electron, React, TypeScript, and FFmpeg, supporting features such as multitrack editing, reverse and freeze-frame effects, and offline speech transcription via MLX Whisper. The project is currently in an early development stage, with specific limitations documented in its feature matrix and various workflow guides. While the editor supports local project management and export, it does not implement cloud synchronization or AI-based portrait cutout features. The project provides a plugin for use within the Codex side panel, subject to specific data boundaries and setup requirements. Development is ongoing, with recent updates adding keyframe curve editing and offline speech capabilities.

Reproduce it
Download the v0.6.0 DMG for macOS Apple Silicon from the official repository. For source builds, clone the repository, ensure Node.js 26 (or 24.11+) and FFmpeg/FFprobe are installed, then run 'npm ci' followed by 'npm run dev'.
