Concat: Free, Open-Source Video Editor Challenges CapCut With Local AI Features and Zero Restrictions

A new open-source video editor called Concat is launching with a direct challenge to CapCut's dominance: every feature runs on your machine, no watermarks appear on exports, and no account or subscription is ever required. The cross-platform editor, available for Windows, macOS, Linux, Android, and iOS, covers the core workflows that make CapCut popular—auto-captions, text-to-speech voices, background removal, effects, and multi-track editing—but with a privacy-first design that keeps all footage and AI models on the user's device.
