How it works

From sheet to level
in minutes.

Four steps. The hard parts happen automatically in between.

1

Upload a tileset

Drop in your spritesheet — and an optional second sheet just for props.

2

Label categories

Tag ground, platforms, sky, props. Auto-Labeler gives you a head start.

3

Generate

Pick a size, seed and shape — Mosaic builds a clean, polished level preview.

4

Export

Place finishing props, then export to your engine of choice. Done.
