AI Image Generation, Without the Friction
Type what you want. Pick a model. Get an image. That's really it. No account, no watermark, no waiting around.
Behind the scenes we're running Google DeepMind's latest image models, so the output quality is genuinely good. You get control over aspect ratio, resolution, and format without needing to know anything about how the models actually work. It's the kind of tool that's useful whether you're mocking something up quickly or actually care about the final result.
Which Model Should You Use?
What's the difference between the Nano Banana models?
All three models run on Google DeepMind technology, but they're built for different things. Here's a quick look at what each one produces so you can pick the right one without having to guess.
bolt Nano Banana
The fastest of the three. Good for quick turnarounds, style transfers, and anything where you want a result in seconds rather than minutes. It handles image-to-image editing well too, blend up to 5 reference photos and it'll pull the subject's likeness across without much fuss.
travel_explore Nano Banana 2
Same speed as the original but with a couple of useful additions. It pulls from Google Search at generation time, which helps when you're asking for something specific, like a real place, a historical period, that kind of thing. Text rendering is noticeably better too, with support for multiple languages. You can feed it up to 14 reference images if you're trying to composite something complex.
workspace_premium Nano Banana Pro
The one to reach for when quality actually matters. It outputs natively at 4K, handles fine typography cleanly, and does a better job with lighting and spatial reasoning. Takes a bit longer than the Flash models, but the difference in output is usually worth it for anything you're planning to actually use.
At-a-Glance Model Comparison
lightbulb Worth knowing
You don't have to commit to one model. A workflow that works well: generate your base image with Nano Banana 2, then bring it into Nano Banana Pro to edit specific parts, add text, or push it to 4K.
How to Generate an AI Image
It takes about a minute from blank prompt to finished image. Here's how it works.
- 1
Write a Prompt Type a description of what you want to see. The more specific you are about subject, style, lighting, and mood, the better the result.
- 2
Choose a Model Pick from Nano Banana, Nano Banana 2, or Nano Banana Pro. Each one has different strengths. Speed, search grounding, 4K output. More on that below.
- 3
Set the Aspect Ratio Square works well for social posts, widescreen for desktop wallpapers, portrait for phone screens.
- 4
Tweak the Settings Open More Settings if you want to change the resolution or output format (JPEG, PNG, WebP). Otherwise the defaults are fine.

Generate Hit the button and your image will appear in a few seconds. Download it or open it full size from the result panel.
Frequently Asked Questions
Is it free?
Yes, completely. No account, no subscription, no credit card. Just type a prompt and go.
Which model should I pick?
If you're not sure, start with Nano Banana, it's fast and handles most things well. If your prompt involves a real place or something specific, Nano Banana 2's search grounding helps. If you're making something you'll actually publish and quality matters, Nano Banana Pro at 4K is worth the extra few seconds.
How do I write a better prompt?
Be specific. Instead of "a dog in a park", try "a golden retriever sitting on a bench in a sun-drenched London park, shallow depth of field, film photography style". Subject, setting, lighting, and style all make a difference. Our Prompt Guide covers this in more detail.
What aspect ratios and formats are available?
Square (1:1), landscape (16:9), portrait (9:16), and several others. Output formats are JPEG, PNG, and WebP. Resolution options depend on the model. Nano Banana Pro goes up to 4K.
Can I download the images?
Yes. Hit the download button in the top corner of the result, or open it full size in a new tab. The images are yours to use however you like.
Can I use the images commercially?
Yes. Images you generate on NeonSnap are yours to use however you like, including for commercial projects. There are no watermarks and no licensing restrictions on the output.
How long does it take to generate an image?
Most images are ready in a few seconds. Nano Banana is the fastest and usually returns a result almost instantly. Nano Banana Pro takes a little longer because it's doing more work, but you're rarely waiting more than 10 to 15 seconds.
