AI Illustration Generator

You write a short prompt describing what you want, pick a style, and an AI model generates the image. The model interprets your text and produces a result in 2 to 10 seconds depending on which model you pick. You can iterate on the same prompt or change it entirely. Each generation costs between 1 and 5 credits depending on the model.

Yes. Everything you generate on renza is yours to use for any purpose, including commercial work, client deliverables, merchandise, and resale. We don't watermark outputs, don't claim ownership, and don't restrict usage beyond standard rules (no depicting real people without permission, respect trademarks).

Between 2 and 3 credits depending on the model you pick. Flux Dev and Hyper Realistic cost 2. Ideogram and Nano Banana 2 cost 3. You get 3 free credits when you sign up; train a personal model and generate on a subscription plan after that.

The default for illustrations is 4:3. This is the format that works best for blog headers, app onboarding, books, editorials. You can change it in the generator if needed (square, 16:9, 9:16, 4:3, 3:4 supported).

Yes. Each Generate click produces a fresh image. Image models are non-deterministic, so the same prompt run twice gives you two different outputs. Tweak one detail (a different adjective, a new noun) to nudge the result, or hit Generate again with the same prompt for a pure variant.

Match the mood to your surrounding copy, and keep a consistent style across a set so your blog or app feels cohesive. And remember the style does the heavy lifting on the look, so spend your prompt describing a strong, specific subject.
