Leonardo

An image platform for game and concept art, with custom style training

Overseas service Free quota Free tierInternational
Open Leonardo

Leonardo.Ai targets art assets that go straight into a project: characters, props, icons and textures that need to form a consistent set. The platform has many presets and ready models, so you pick one and adjust the prompt. It also lets you train a custom model on your own images to lock a project style, which general image tools rarely cover. For game or commercial use, check the platform terms and the documentation for the base model.

What it does

  • Preset models and style libraries for game art and concept design
  • Train a custom model on your own images to lock a style
  • Canvas editing, inpainting and outpainting
  • Real-time assistance such as sketch-to-image
  • Results sorted into project albums for set selection

Who it is for

  • Batch icons, props and character drafts for an indie game or prototype
  • Your own artwork should define the style of future generations
  • Concept work needs multiple options with one visual language
  • Change backgrounds or extend the edges of existing assets

How to get started

  1. Pick a model close to the target style instead of writing from zero
  2. Run several images from one prompt and confirm the style holds before scaling
  3. For custom training, first prepare a clean, consistent image set
