Nano Pro is a standalone online AI image editing and generation workspace, with the website https://nanopro.app/。它把 Google's three image models—Nano Banana, Nano Banana Pro, and Nano Banana 2—are placed in the same browser tab, and users do not need to set up an API key or billing account and can use them via credits.
[Main Capabilities] Nano Pro's core features include: photo-to-photo editing, that is, after uploading an image, describing in natural language what needs to be changed (such as changing the background, adjusting lighting, or changing the season or style), while keeping the subject unchanged; text-only image generation, which does not require uploading a photo, and can generate by describing the scene, lens, and atmosphere, with the option to choose aspect ratios from square to 21:9, and output 1K, 2K, or 4K when supported by the selected model; in-image text rendering, where posters, labels, and packaging mockups can contain real headline text, and the Pro and 2 models are clearly superior to the base model in text layout; multi-reference image blending, where Nano Banana 2 can read up to 14 reference images and merge people, clothing, products, and scenes into one coherent image; multiple aspect ratio outputs, including square, 21:9 banner, and extreme 8:1 or 1:8 strips.
[How to Use] Users can register for a free account via Google or email, and after registering receive 15 welcome credits, valid for 30 days, which can be used to generate one image with the fast model. The usage flow is: select a model and upload a photo (or leave it blank to generate from text only), write the description content (explain the people or objects, position, lighting, and style in the image, and you may include HEX color codes or text that needs to appear), compare the results of different models, make one modification per request for gradual refinement, and finally download as PNG or WebP format. All generation results are saved in My Creations along with the prompts, and can be reopened at any time to continue editing.
[Credits and Plans] The credit consumption for generating one image depends on the model and resolution: the fast model requires 15 credits, Nano Banana 2 requires 30 to 60 credits, and Pro requires 60 to 80 credits; other engines such as GPT Image 2 start from 10 credits, while Seedream or Grok Imagine are 15 to 25 credits. The specific price is displayed on the generate button before confirmation. Paid plans include the Basic annual plan (800 credits per month, up to about 80 images/month), the Pro annual plan (2000 credits per month, up to about 200 images/month), and Enterprise Annual plan (6,000 credits per month, up to about 600 images/month), all paid options can remove download watermarks. The annual plan is half price during the launch offer.
[Use cases] This tool is suitable for ad variant creation (changing the environment, time period, or art style of approved images for social ads or multi-directional testing), catalog images and virtual try-on (placing product images into lifestyle scenes or market backgrounds, and previewing outfit effects with clothing reference images), fixed-character creation (providing turnaround sheets, storyboards, and episode thumbnails for illustrators, indie game teams, and comic creators), and everyday retouching (removing background passersby, adjusting sky color, expanding the frame, changing clothing color, etc.).
[Limitations and notes] Nano Pro is an independent service that connects to Google's image models and models from other labs through third-party API providers; model behavior and availability may change as providers update. Free images carry a small watermark, while paid plans remove watermarks. The official guidance reminds users to confirm they have permission to use faces before uploading them, and to check similarity before publishing. Plans with commercial licensing can cover commercial uses such as advertising, product listings, and client projects, subject to the terms of service.
