How to use Erasio
A complete walkthrough from installation to your first clean image download.
Install the Extension
Visit the Chrome Web Store and click "Add to Chrome". Installation takes about 5 seconds.

Erasio — Gemini Watermark Remover
Browser extension
Open Google Gemini
Navigate to gemini.google.com or Google AI Studio. The Erasio icon in your Chrome toolbar turns active, confirming it's ready.
Erasio only activates on gemini.google.com. It doesn't run on any other website and never monitors your general browsing.
Generate Your Image
Create any image with Gemini as you normally would. No changes to your workflow needed — Erasio listens in the background.
Erasio monitors download events. It doesn't intercept, slow down, or alter your image generation requests in any way.
