Leonardo AI

Leonardo AI is an image generation platform aimed at creators who need consistency across many images — game developers needing consistent character/asset styles, or brands wanting a recognizable visual identity. Its model-training feature lets you fine-tune a custom model on a set of reference images so future generations match that style or character, and "Realtime Canvas" lets you sketch rough shapes and see AI-rendered results update live as you draw, useful for iterative concept work. It includes specific tooling for game assets (textures, sprites, icons) alongside general image generation. The free tier provides a daily allowance of generation credits — enough to explore the platform, though heavy users will exhaust it quickly; paid plans starting around $12/mo provide substantially more daily credits and priority generation. Training custom models takes both time and credits, and the interface, with its many modes and settings, has more of a learning curve than simpler single-purpose generators.
