Alternative to Leonardo AI
Leonardo's AI image generator is indeed a good image generator after MidJourney.
You may have left MidJourney because the limit was exceeded. Or you have upgraded the plan.
Leonardo allows you to produce free AI images with daily renewal credits, which are sufficient to experiment with art styles. You can buy more because the AI tool is worthwhile to use. If you know how to use prompts appropriately, you will undoubtedly receive greater results.
There are many more similar tools to generate images one is here mage space. Not all free but you can still generate good images for all day.
