NanoBananaEditor

Nano Banana Editor is a web based image generator and editor built on Google's Gemini image models. A user describes an image in a prompt composer, adds reference photos if wanted, and can ground the result in real world information. Output is available at up to 4K resolution. The site presents it as a single editor covering every Nano Banana model, with example prompts such as editorial photography, isometric illustration, posters with headline text and macro shots. The project is described as free and open source, released under the AGPL 3.0 license with source on GitHub, and it is credited to Mark Fulton of Reinventing.AI. Using the hosted demo requires creating an account with an email and password, which includes agreeing to receive occasional updates about new Reinventing.AI tools and sessions. New accounts start with 5 free credits. The tool suits designers, marketers and hobbyists who want to try Gemini image generation and editing through a simple interface rather than building against the API themselves. The site does not publish prices for credits beyond the 5 free ones, and it shows no paid plan tiers.
