Leonardo AI

Leonardo AI is a web-based image generation platform built on Stable Diffusion but wrapped in an accessible interface with serious power-user features. In 2025, it runs SDXL and fine-tuned community models, offers ControlNet integration for pose and structure control, and lets you train custom models on your own images — all through a browser with no GPU required.

Pricing: free tier gives 150 tokens/day (roughly 10-15 generations), Apprentice Lite at $10/month (8,500 tokens), Artisan Unlimited at $24/month (25,000 tokens + priority). The free tier is the most generous in this market — 150 daily tokens is enough for regular creative work without paying anything.

The real differentiator is the ecosystem: thousands of community-fine-tuned models covering anime, architectural photography, product mockups, and game assets. For indie game developers, this combination of access and quality is unmatched. For general marketing visuals, Midjourney still produces more polished results, but Leonardo's free tier makes it the smart starting point for anyone budget-conscious.
