From one prompt to
game-ready sprite atlas

Drop a character photo; idle/walk/attack rows fall out clean. AI makes the pixels, determinism polishes them. Private beta — clicking Generate auto-joins the waitlist.

PIPELINE OUTPUT

Determinism tames the noise

AI gen → chroma key → connected components → cell-based atlas → manifest. Same input → same result (idempotent).

PIPELINE

Deterministic post

Chroma key, connected components, atlas compose, manifest. 12 Python scripts on Pillow + stdlib only. Determinism on top of AI noise.

AGENT

Agent-native skill

Claude Code / Codex are first-class. SKILL.md specifies workflow, output contract, gates. Human or agent, same output.

ENGINE

Manifest = contract

sprite-request.json (input) + manifest.json (output) are the SSoT. Unity AssetImporter / Godot resource / Phaser spritesheet consume the same contract.
