NanoBananaEditor

What it does

Generate an image, then refine it in conversation — including region-scoped edits, so you change one part instead of rerolling the whole thing, with the edit history preserved. Gemini does the generation, which means your images and prompts go to Google and commercial rights follow Google's terms rather than this repo's. AGPL-3.0 matters if you modify it and offer it to others. Don't alter photos of real people without their say-so. Quiet since May 2026.

NanoBananaEditor FAQ

Is NanoBananaEditor free?

NanoBananaEditor itself is free, but it needs an API key for an external AI service. That service charges separately, though some have a free tier.

Do I need to install anything or write code to use NanoBananaEditor?

It needs the command line. If you are not comfortable typing commands, expect to get stuck during setup.

Does NanoBananaEditor work on a phone?

No. It needs a computer.

Can I use NanoBananaEditor commercially?

The licence is AGPL-3.0. Using it commercially is fine, but if you distribute something built on it you may be required to release that under the same licence. Keep it internal, or check before distributing.
