Leonardo AI
AI image generation and editing suite with fine control and an API
About
Leonardo AI is a creative platform for generating and editing images, with text-to-image generation, image guidance, upscaling, a canvas editor, and background removal. It is popular for game assets, concept art, and marketing visuals, and it is also the service that remove.bg's background removal moves to starting December 1, 2026. It is best for users who want more control — styles, elements, prompt guidance — than a plain prompt box offers.
No install — web app at app.leonardo.ai. Sign up at https://leonardo.ai (a free tier is available). Developers: Leonardo offers a Developer API, linked from their homepage, for programmatic image generation.
