100% client-side — your audio never leaves the device
Every chord.
Every key. Instantly.
Drop in any song — or just play — and a custom DSP engine maps out every chord, spots the song's main progression, finds the key, and hands you a beat-aligned MIDI file. Guitar tabs included when you want them.
