Img Gen Playground

Img Gen Playground is a straightforward web tool that lets you generate images from text descriptions and edit existing ones using AI. You type what you want, optionally upload one or two reference photos, choose an aspect ratio from ten options, select one of the available models, and click Run. The tool calls Google's Gemini 3 models under the hood and returns the result on the same page. No sign-ups or subscriptions required — you just buy credits via Stripe and use them per generation.

What makes it interesting is the range of models. There's Nano Banana 2 (Gemini 3.1 Flash) where you can adjust thinking effort and output resolution up to 4K, a Pro mode (Gemini 3 Pro) for highest quality, and a Classic mode (Gemini 2.5 Flash) for speed. The Nano Banana 2 mode also supports Google Search grounding, so it can pull in real‑world context if your prompt needs it. You get no watermarks on any generated image, which is nice for quick mockups or social media visuals.

This tool is best for people who need occasional AI images without committing to a monthly subscription. Content creators can mock up social graphics, designers can iterate on concepts, and hobbyists can experiment with different styles. The pay‑per‑generation model means you only pay for what you actually use. It's simple, no frills, and does exactly what it says.
