i'm doing a (free) media format conversion program (just a hobby, wont be big and professional like GNU) for macOS. It's not total vibe coding but I didn't realize how awesome AI could make stuff before it was better (in my opinion) then anything i've ever tried before. now i'm being semi-disciplined with it. Converts video, pictures, audio to/from any format ffmpeg backend (currently it has the fat proprietary codec included ffmpeg build which isnt open source compatible but literally supports everything) really slick looking interface that adheres to apple design philosophy has cool ✅, ❌and 🔄 simple coherent and useful interface that doesnt have all the nonsense and overly complicated options programs like this typically have. no cumbersom file dialog boxes, drag and drop and in-place output I just made the github repo public and haven't got around to including release builds or a trendy looking README.md yet https://github.com/jsarasin/MacConvert
