THE CHROME COMPANIONNano Banana 2.1
Prompt Helper
A good image starts with a clear brief. Build a prompt from a practical template, make it your own, and keep your favorite ideas close at hand in Chrome.
Chrome Web Store release is being prepared. An installation link will appear here after approval.
Open the image generator ↗Your next prompt, in a few steps.
- Choose a starting point. Pick one of eight templates for studio or lifestyle product photos, event posters, social graphics, editorial or character illustrations, and reference photo edits.
- Add the details. Describe your subject, setting, light and the details to preserve. The prompt updates as you type. You can edit the final wording directly.
- Copy it or keep it. Copy the prompt, save a named version locally, or revisit your automatically saved draft later.
- Create an image when ready. Open the website, paste your prompt and choose your image settings. For reference edits, upload your photo on the website.
A small tool for ideas you want to reuse.
Create and edit prompts offline. Save up to 100 prompts, search your collection, copy or reuse a saved prompt, and delete it whenever you like. Your draft and collection stay in this Chrome profile. There is no cloud sync, no extension account and no subscription for the prompt tools.
The extension requests only the storage permission. It does not read your browsing history or the contents of websites, and does not send your prompt to a server. Copying a prompt writes it to your system clipboard at your request.
Before you start
Does the extension generate images?
It helps you prepare prompts. Image generation and photo editing happen on nanobanana-21.app and require a website account and credits. Copy your prompt and paste it into the website; it is not automatically transferred.
How do I remove my saved prompts?
Delete an individual item from Saved Prompts, or choose Clear all local data to remove your collection and reset your draft. Uninstalling the extension also removes its local storage.
Is this a Google extension?
No. This is a companion tool from nanobanana-21.app, and is not affiliated with or endorsed by Google.
