How do I activate my license after purchase?

After purchase, Polar emails your license details. Enter your license in the extension settings to unlock the full workflow.

Does this work with a free Gemini account?

Yes. Banana Shake works with any active Gemini account, including the free tier, for the core automation flow.

What happens when my free trial ends?

You receive a reminder before the trial expires. If you do not upgrade, access falls back while your existing data stays intact.

Can I use Banana Shake on multiple computers?

Each license is intended for one active device at a time. You can deactivate on one machine and reactivate on another.

Is my Google data safe?

Banana Shake uses Google OAuth and only requests the permissions needed to automate Sheets, Drive, and Gemini actions. Your data is never stored on our servers.

How do I cancel my subscription?

You can cancel from the extension settings or from the Polar dashboard linked in your purchase email.

What if a row fails during bulk image generation?

Failed rows are retried automatically. Permanent failures are marked clearly in the Sheet so you can review them later.

How to Automate Gemini Image Generation with Google Sheets

Manual AI image generation is a bottleneck for high-velocity teams. If you find yourself copying and pasting prompts into a web interface all day, you are doing it wrong.

The Problem with Manual Workflows

Every time you want a new image, you have to type the prompt, wait for the generation, and manually save the file. If you need 50 images, that’s 3 hours of your life gone.

Enter Gemini Automation

With Banana Shake, you can list all your prompts in a Google Sheet. One row equals one image job. Click start, and the Chrome extension handles everything: prompt submission, capturing the full-resolution image, and saving it to Google Drive.
