Nano Banana 2.1 is a browser-based AI image generator and editor at nanobanana21.com that builds on Nano Banana 2, accepting text prompts plus up to 14 reference images and returning finished pictures at 1K, 2K or 4K with legible text rendered inside the frame.
Nano Banana 2.1 is the upgrade listing for Nano Banana 2, which the page identifies as Gemini 3.1 Flash Image, and the all-round Nano Banana model for creating and editing images. You type a prompt, optionally upload up to 14 reference photos of people, products or places, choose an aspect ratio and a resolution, and the generator returns a finished image; nothing is installed and the whole tool runs in the browser. The page is explicit that the generator itself currently opens on Nano Banana 2, with Nano Banana Pro, Nano Banana 2 Lite and the original Nano Banana selectable from the same model picker.
The workflow has four steps. Describe the image, including any words that should appear in it. Add up to 14 references and refer to them as Image 1, Image 2 and so on in the prompt to say what goes where. Choose the model, aspect ratio and size. Generate, compare against your references, adjust one prompt line if needed, and download.
New accounts get 10 free credits, enough for a first 1K image (up to 2 images), with a watermark and no card required. Paid monthly or yearly tiers are Basic (1,000 base credits plus a limited-time 500 bonus, up to 375 images), Standard (3,000 plus 1,000, up to 1,000 images) and Pro (8,000 plus 2,000, up to 2,500 images); switching to yearly is advertised as saving 30%, listed as $60, $120 and $360 a year respectively. Paid plans add HD resolution, batch generation, no watermark, a commercial use license, instant starts and creations kept while subscribed; failed runs are refunded automatically and a first-payment discount of up to 20% is applied at checkout.

The generator opens on Nano Banana 2, the model Nano Banana 2.1 builds on. The model menu shows which one is selected, and you can switch to Nano Banana Pro for detail-heavy professional work, Nano Banana 2 Lite for fast drafts, or the original Nano Banana.
Up to 14 with Nano Banana 2, which is the highest limit in the family. Nano Banana Pro accepts up to 8 references, while Nano Banana 2 Lite and the original Nano Banana each take up to 10.
Yes. Write the exact words in quotes inside the prompt and say where they go. For an image you already have, upload it and ask for the text in another language to localize the layout while colors and photography stay intact.
Paid plans include a commercial use license and remove the watermark; free-tier images keep one. You are responsible for holding the rights to any photos, logos or likenesses you upload as references.
