Project overview
GeminiWatermarkTool is a local desktop and command-line application for detecting and removing visible overlay watermarks from Gemini-generated images. It supports current Gemini 3.5 profiles with automatic legacy fallback, batch processing, and optional denoising. Full GUI and smaller CLI builds are available for Windows, Linux, and macOS, with the compact edition suited to scripts and CI. It does not remove invisible SynthID marks, and video processing belongs to a separate related project.
