Four charting engines — we pick the right one for you

Onset — Millisecond-Precise Charting

A convolutional-recurrent network hears every drum hit directly from the audio, unconstrained by any grid. Best accuracy for tempo-changing songs and 24th-note passages.

Neural — Phrase Model

An autoregressive decoder generates note by note, producing phrase structures closest to human-authored charts.

Hybrid — Best of Both

Uses a neural draft to guide retrieval-based re-ranking, balancing accuracy and playability.

Auto — Smart Routing

Analyzes the song’s rhythmic complexity and event density first, then decides which engine to use. This is the default.

It also handles all of this for you

BPM & Start Offset
Integer snapping plus phase-drift testing avoids misreads like 149.987 when it should be 150.
Tempo-change detection
Automatically finds BPM changes within the song and writes them as BPMCHANGE.
GOGO TIME
A measure-sequence model identifies the climactic sections.
Rolls & Balloons
Learned detection, with duration verified against the actual audio envelope.
Multi-difficulty in one click
Generate all four difficulties — Easy/Normal/Hard/Oni — for one song at once.
Adjustable parameters
Fine-tune density, roll amount, and big-note ratio yourself.
About the music you upload: Your audio is kept alongside the finished chart for up to 30 days so you can download both at once and preview them right away. Only the audio is deleted afterwards — the charts you generated are kept indefinitely. Accessible only from your own account; we never redistribute it and never use it to train models. You must hold the rights to any music you upload. See Terms of Service
