Raphael AI has positioned itself as a completely free AI image generator since its launch. We spent two weeks testing the image generation, style options, and overall user experience. The zero-cost model impressed us—but some limitations are worth noting.
Raphael AI offers decent free image generation with no signup required, but watermarks on free images, limited resolution (1024x1024), and basic features hold it back for serious creators. Rating: 3.5/5

Frequently Asked Questions
Final Verdict
Raphael AI Rating: 3.5/5
Raphael AI delivers on its promise of free, no-signup image generation, making it an excellent entry point for beginners curious about AI art. The zero data retention policy is a nice privacy touch.
However, the watermarks on free images, 1024px resolution limit, and lack of saved history are significant limitations for anyone doing serious creative work. The browser-only storage means one accidental refresh destroys all your work.
Our recommendation: If you want to experiment with AI image generation without any friction, Raphael AI is a fine starting point. But for regular creative work where you need higher quality, saved history, and no watermarks, Kosoku AI offers a superior experience with blazing fast generation and a proper gallery to save your creations.
