Ever wanted to generate AI images without leaving your browser tab? We just shipped a Chrome extension that does exactly that.

What It Does

  • Text to Image: Type a prompt in the popup, get an AI-generated image instantly
  • Right-Click Edit: See any image on the web? Right-click → "Edit with NanoBanana2" → transform it with AI
  • Multiple Models: Choose between Standard and Pro (powered by Google Gemini)
  • 4K Output: Generate images up to 4096×4096 resolution

Why We Built It

Most AI image generators require you to open a new tab, log in, wait for the page to load... We wanted something faster. The extension lives in your browser toolbar — click, type, generate. That's it.

Try It

The extension is currently in review on the Chrome Web Store. In the meantime, you can try the full web version at NanoBanana2 — free credits included for new users.

Tech Stack

  • Manifest V3
  • Google Gemini API via NanoBanana2 backend
  • Vanilla JS (no frameworks needed for a popup)
