We built this for a pretty simple reason. A lot of musician friends we talked to told us they were curious about using AI to transcribe MP3 to MIDI, but they always hesitated because they didn't feel comfortable uploading their audio files to some random server. Nobody wants their unreleased tracks or original melodies sitting on someone else's cloud, not knowing if it might get leaked or misused. So we figured, why not make something that runs entirely locally? You open the page, pick your file, and the whole conversion and editing process happens right in your browser. Your files never leave your device. That way you get the convenience of AI without having to worry about privacy. Another thing we cared about was that most converters just give you a raw MIDI file you can't touch. But AI isn't perfect—it sometimes misreads notes or misses little details. So we decided to build a built-in editor as well. You can tweak notes directly on the web page without needing to open a separate DAW just to fix things. This version we have now feels pretty solid and useful. If you have any thoughts on the conversion or editing side, we'd love to hear them—we're still improving things.
