Erasio applies advanced computational methods to analyze and reconstruct image data. Using calibrated reference patterns, the engine identifies and removes embedded watermark layers with high precision.

• Reference pattern calibration
• Pixel-level reconstruction
• Adaptive processing per image

The watermark detection system locates the mark's footprint by comparing luminance and color channel data. The reconstruction phase restores the underlying original content without visible artifacts.

• Multi-channel analysis
• Artifact-free reconstruction
• Sub-pixel accuracy

All processing runs inside the Chrome Extension using the browser's built-in Canvas and WebAssembly APIs. There is no server, no cloud uploads, and no third-party processing — ever.

• Canvas API rendering
• No network calls for processing
• Zero data exposure

The extension hooks into Gemini's download flow at the browser level, processing images transparently before they reach your file system. The experience is fully seamless.

• Native browser integration
• Pre-download processing
• Transparent to user workflow

Erasio maintains a library of known Gemini watermark signatures, including the Nano Banana compact-overlay pattern. The engine automatically selects the correct removal strategy based on the detected pattern, ensuring accurate reconstruction across all Gemini model outputs.

• Multi-pattern signature library
• Nano Banana compact overlay support
• Automatic pattern detection & selection
