What is NanoBananaTool?
NanoBananaTool is a web-based Nano Banana tool for text-driven image editing and AI-generated images. Instead of working with layers and brushes, users write a description of what they want and the AI applies the change. It offers a Text to Image mode for creating images from scratch and an Image to Image mode for editing uploaded pictures, with the goal of high-fidelity image editing that keeps characters consistent.
Users can upload up to six reference images in JPG, PNG or WebP format, each under 5 MB, and the AI combines elements from them into one result. A generation typically takes 30 to 60 seconds. The site also includes Banana Agent, a chat-based assistant that produces images and videos through conversation, and Banana Prompts, a library of example prompts. Generated images may be used commercially, and uploads are not used for model training.
Who it's for
- Illustrators and concept artists
