Runner
Dreams the coarse map, super-resolves it to a full grid, and sets the cube, ship, and wave flow. Tuned for levels that connect and clear.
24×8 → 96×32 grid

An AI copilot that lives inside the Geometry Dash editor. Select a section, tell it what you want, and it builds real, physics-checked geometry in place. The way Cursor works for code.

Everything gdgen builds runs on two models. Runner owns what you play. Chroma owns what you see. Neither one can reach into the other’s job.
Between them sits a physics gate: the gameplay has to be proven beatable before Chroma is ever allowed to touch it. That’s why a loud redesign can never make a level impossible.

what you see
Layers deco, palette, and color triggers over finished geometry it never moves. The look is a coat over the level, not a rewrite of it.
deco · palette · triggers

A chain of small, specialized models. Each owns one job, and the gameplay is finished and physics-checked before design begins.

A GPT dreams a coarse 24×8 map, column by column, so left-to-right flow and connectivity come for free. It's the level's skeleton: where floors, gaps, and beats fall, before a single object exists.
The copilot lives in your editor and builds alongside you. Or skip straight to a finished level from a song. Both compile to real, physics-checked GD.
the copilot
Select geometry, say what you want, and Claude builds the change in place. Apply, revert, iterate, without leaving the editor. It’s Cursor, for Geometry Dash.

An AI copilot that lives inside the Geometry Dash editor. Think Cursor or Claude Code, but for levels instead of code.
Select some geometry, say what you want, and it builds the change in place: real GD objects, applied to your level, with a revert chip on every edit.
You highlight a section and describe the change. Claude designs it, compiles it to real GD objects, and applies it right where you're working.
Nothing is a black box: every edit is a chip you can revert one at a time, so you stay in control of the level.
No. Layout and design are separate passes: the gameplay is finished and physics-checked before design ever touches it, and design never moves a hitbox.
And any edit can be reverted, one chip at a time.
Yes. Hand it a curated track and a difficulty and the generator designs a complete level synced to the beat, no editing required.
It's the same models the copilot uses, pointed at a blank canvas instead of your selection.
Yes. A physics simulator plays every section before a level ships and rejects anything impossible.
So what you download is always clearable, not a wall of spikes no human could pass.
Every level page has a .gmd download you import straight into your created levels.
Or use the Geode mod to browse the newest levels and import them in one click, without leaving the game.
No. The copilot, generating, and downloading are free to start, with no signup and no account.
A curated set of Newgrounds tracks, each with a human-verified BPM grid, so every pattern lands on the beat.
No. gdgen is a fan project, not affiliated with or endorsed by RobTop Games.
The whole project lives on GitHub, from the model pipeline to the compiler and the Geode mod.
