How it works
Technical Implementation
Deterministic Restoration, Not AI Inpainting.
Unlike generic AI object removers that guess what goes behind the watermark, ToolKB uses a mathematical reverse-alpha blending approach. Because the visible Gemini watermark is applied as a translucent overlay with a known alpha channel, the underlying original pixel values can often be recovered directly through mathematical inversion.
