All we do is drums.
Upload a song and get the drum part back as real sheet music: kick, snare, hi-hat, toms, crash and ride, each on its own line. Then slow it down, loop it and play along.
Your first song is free. No card.
On public benchmarks it gets more than 8 in 10 drum hits right, and it flags the ones it isn’t sure about. See every number

We pull the drums out
One model separates the kit from the rest of the mix. A second one, trained only on drums, writes down every hit.
Practice it
Real notation with a cursor that follows the recording. Slow it down, loop a bar, fix a note, print it.
Built for the practice room.
Every chart opens in a player made for learning a part, not just reading it.
Slow it down
− / +Practice at 50% and work back up in 5% steps, until it's at tempo.
Loop the hard bar
L · IDrag across the notation to loop a fill or a section, with a one-bar count-in if you want one.
Hear just the drums
mix ⇄ drumsSwitch between the full mix and the isolated drum track to hear exactly what was played.
Click along
MA metronome that follows the song's own beats, so it stays with the band when the tempo drifts.
Fix what's off

The honest numbers.
On two public drum benchmarks it gets more than 8 in 10 hits right. Kick, snare and hi-hat are its strong suit. Toms and crashes are where it still misses, so those are the notes it flags for you to check.
Measured October 2026 on ENST-Drums and MDB Drums, recordings our models never trained on. A hit only counts if it’s the right drum at the right time, and every extra note counts against us. Each figure is the range across the two benchmarks, rounded down.

- Hi-hat90%

F1 score per drum, shown as a percentage. Same model you get today.
It tells you which notes to double-check.
No transcriber is perfect, us included. Paradiddle flags the handful of hits it was least sure about and says why, so you check those instead of combing the whole song. Keep or fix each one in a tap.
