What is Growmark?
Growmark is a professional-grade AI watermark removal tool developed by Growistan Venture. It uses a mathematically precise technique called reverse alpha-blending to recover original pixels that have been overlaid by Gemini AI's watermark system.
Unlike competing tools that rely on inpainting or generative models to guess what's beneath, Growmark uses the exact inverse of the compositing formula — which means results are deterministic, pixel-accurate, and lossless.
