About Play Anything

Our first product, Songscription, is the AI-powered "Shazam for sheet music" that turns any audio into sheet music, MIDI, tabs, or an interactive piano roll in minutes. Hundreds of thousands of musicians have used it to transcribe songs that had never been written down before. Our second product, Anything Piano (in beta), lets anyone upload a song and learn it through an interactive piano roll with real-time feedback.

We've raised a $5M seed led by Reach Capital and been covered in TechCrunch, Billboard, and MusicRadar. The team is small, the pace is fast, and we're just getting started.
