Install the Extension

The extension requests only the permissions it needs: access to Gemini's download events and local storage for your preferences. No personal data is collected.
Erasio — Gemini Watermark Remover
Browser extension
Open Google Gemini
Navigate to gemini.google.com, Google AI Studio, or Google Flow (labs.google/fx/tools/flow). The Erasio icon in your Chrome toolbar turns active, confirming it's ready.
Erasio only activates on gemini.google.com, Google AI Studio, and Google Flow (labs.google/fx/tools/flow). It doesn't run on any other website and never monitors your general browsing.
Generate an Image or Video
Create any image or video 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 or video generation requests in any way.

Download Watermark-Free
Click the download button on any Gemini image or video. The file saves to your computer instantly — clean and without any watermark.
For images, reverse alpha blending runs in microseconds; for video, Erasio re-renders each frame and keeps the original audio. The watermark is removed and the clean file hits your downloads folder.
