Banananana

Banananana is an AI-powered image generation service that lets you create up to 16 image variations simultaneously. By running parallel generations, you can explore design possibilities up to 16x faster than traditional tools.

When you submit a prompt, Banananana sends multiple requests to the AI model at once. As each image completes, it appears on your screen immediately—no waiting for all images to finish. This streaming approach maximizes your creative exploration speed.

Banananana uses Google's Gemini API for image generation. You can choose between Nano Banana (gemini-2.5-flash-image, faster, 1 coin per image) and Nano Banana Pro (gemini-3-pro-image-preview, higher quality, 4 coins per image) depending on your needs.

You receive 4 free coins daily that reset at midnight (JST). Each Nano Banana generation costs 1 coin, while Nano Banana Pro costs 4 coins. 4K resolution doubles the cost. Free coins are used first before any purchased coins.

Yes. To maximize your privacy, generated images are never stored on Banananana's servers. They are streamed directly to your browser. This means if you close the browser or reload the page, the images will no longer be viewable unless you've downloaded them. This is a trade-off we've made to prioritize your privacy.

Banananana does not store your prompts or reference images. They are sent directly to Google's servers for processing. According to Google's terms, this data is not used for model training. Your creative inputs remain private.

Usage rights depend on Google's Gemini API terms of service. Generally, AI-generated images can be used for personal and commercial purposes, but we recommend reviewing the latest Gemini usage policies for your specific use case.

Images are generated in PNG format. You can choose from multiple aspect ratios including 1:1 (square), 16:9 (landscape), 9:16 (portrait), 4:3, and 3:4. The 4K option provides higher resolution output.

After generation, you can select individual images by clicking the checkbox on each card. Then use the download button to save selected images as a ZIP file. You can also click on any image to view it in full size.
