FEATURES

Every step of charting, in one app

From a blank project to a community release, without a second tool.

01 / PROJECT

One song, one project — every difficulty, audio and cover in one place, with progress and release state tracked for you
Start from anywhere: blank, a copied project, an official chart, or one imported from the community
Bestdori integration: browse the library and sign in inside the app, then publish a finished chart in one click

02 / EDIT

Seamless with the Bestdori editor: the same keys and conventions you already know, and chart code in the same community format
Deep slide editing and a curve brush: draw a bend along its path, then add or remove joints, split and mirror
Drag to edit: drag notes along the beat grid, drag curves along their path, or move a whole selection at once
Fully remappable shortcuts: one key per action, conflicts rejected, applied the moment you change them

03 / PREVIEW & EXPORT

Static preview: the whole chart laid out as one sheet, with continuous zoom
Live preview: a full replay on the simulation stage, matching in-game notes, effects and combo
Chart image export: the whole chart as one long image with a song-info header, ready for community posts
Preview video export: simulation replay rendered frame by frame into a video for video platforms

NO TELEMETRY: Troubleshoot with in-app diagnostic bundles: version, environment, logs, actions.

PORTABLE: Export and import settings; move machines with a single JSON file.
