ClipForge Local is a local-first macOS app that turns a long YouTube video into ready-to-post shorts. Give it a URL and it transcribes the video, identifies viable short-form moments, and exports them as 9:16 vertical clips with burned-in subtitles. Before any clip surfaces in the UI, the app verifies the file actually exists and rendered correctly — no ghost entries pointing at missing files.
Running locally means your source videos and API usage stay on your machine, and the render pipeline is yours to inspect. It is built on Next.js and TypeScript with ffmpeg for editing and Whisper for transcription. Verifying each rendered file before it appears means the library never shows a clip that quietly failed to export, and running everything locally keeps both your source videos and your API usage on your own machine rather than a hosted service.
