What it does
General image and video generation platform with trainable custom models; usable for concept art, item icons and texture ideas.
Pixel-art-specific image models for sprites, tiles, tilesets and animations, plus low-poly 3D model generation with export for Godot, Unity and Unreal. Also sells an Aseprite extension.
Verdict
For general concept art and icon ideas; free-tier output can be used commercially but is public and Leonardo holds rights to it, while paid plans give you ownership.
For pixel-art devs who want pay-per-image pricing with no subscription; the site says all output is yours for commercial use.
