Leonardo (by Canva) is an AI image generator built around fine control: multiple models, fine-tuning, and a generous free tier that keeps a non-exclusive commercial license even on the free plan.
Free plan gives 150 credits/day (roughly 25-37 images) across all models, with a commercial license included: rare for a free tier. Paid plans (Apprentice $10/mo, Artisan $24/mo, Maestro $48/mo annual) add higher token pools, video generation and API access.
Designers and small teams who want to experiment across many diffusion models (not locked to one house style) without paying up front, and indie creators who need commercial rights on a budget.
Test the free tier's daily credit reset before committing. 150 credits/day is enough for regular exploratory use, but production/API work needs a paid tier.
