How it works
The generator is built around one fast loop: describe, configure, generate. You can refine and re-run as many times as your credits allow.
- Enter your prompt — describe the subject, style, lighting, and use
- Choose a model, aspect ratio, and resolution
- Generate, then remix, download, or share the result

Frequently asked questions
Is this AI image generator free?
Yes. You can generate your first images free with no credit card. Signed-in users can claim daily credits for ongoing generation, and paid plans or credit packs cover higher-volume work.
Do I need to sign up?
No. You can try the generator as a guest with a limited number of free generations. Create a free account when you want daily credits, saved history, and download-ready results.
Can I use the generated images commercially?
Generated images are intended for commercial workflows such as ads, product mockups, social posts, and client concepts. Review your plan terms before publishing at scale, and avoid recreating trademarked or copyrighted material.
Which model should I choose?
Start with Nano Banana 2 for fast general generation, or Nano Banana Pro when you need higher fidelity and clean text rendering. Flux 2, Imagen 4, Seedream 4.5, and GPT Image 2 are available for more stylized or experimental looks.
Can I generate images from text?
Yes. Text-to-image is the default mode — type a prompt, pick a model and aspect ratio, and generate. Clear prompts that name the subject, style, lighting, and intended use produce the strongest results.
Can I edit an existing image?
Models that support image input let you upload a reference image and transform it with a prompt. Models without image input are text-to-image only; the generator shows which mode each model supports.
Are downloads watermarked?
No. Exports are watermark-free so you can use them directly in your own projects.
How do daily credits work?
Signed-in users can claim a daily allotment of credits. Each generation spends credits based on resolution and the number of images. Come back the next day to claim again, or top up with a plan or credit pack for heavier use.
