Every chord.
As it plays.

Drop in a song. Get its chords, key and tempo on a beat-locked timeline — with the shapes under your fingers as it plays.

How it works

Hear it. See it.
Play it.

Load a track and it works out the chords, the key and the beat — then lines up the shapes and the words so you can just play along.

Chords you can trust

Majors, minors, sevenths, sus, sixths, diminished and augmented — every chord type on every root, straight from the recording.

Locked to the beat

Key, tempo and time signature detected, then a rigid grid with octave correction keeps the 1-2-3-4 count true even through a quiet intro.

Guitar · ukulele · piano

Real fingering diagrams for the chord playing right now — and the one coming next, with a countdown so your hand is ready.

Transpose that moves the audio

Shift up to three semitones either way and the song itself changes key — pitch moves, tempo stays put, so the grid still lines up. Capo too, clearly labelled.

Lyrics in any language

Time-synced words that scroll with the song — Hindi, Malayalam, English, anything — in their own script, or laid out chords-over-lyrics.

Practise at your pace

Slow to 0.75× or 0.5× without losing pitch, and pick Beginner, Intermediate or Expert to simplify the harmony while you learn it.
