## What it is
A C++20 tool that detects and removes the Gemini/Nano Banana Pro and Veo watermarks from AI-generated images using calibrated reverse alpha-blending masks, with both GUI and CLI interfaces. It supports multiple watermark profiles (including free-tier half-scale and Gemini 3.5), optional AI denoising via FDnCNN on Vulkan GPU, and an MCP server for integrations.

## Use cases
- remove gemini watermark from ai generated images
- clean veo video watermarks
- restore image detail under the nano banana pro watermark
- batch remove watermarks from gemini free-tier half-scale images
- integrate watermark removal into an agent via mcp
- run watermark removal offline without cloud services

## When to choose
- you need offline, local removal of Gemini/Veo watermarks with high fidelity
- you want both a drag-and-drop GUI and a scriptable CLI
- you need support for the latest Gemini 3.5 and free-tier watermark profiles

## When to avoid
- you need to remove arbitrary or non-Gemini watermarks
- you want a cloud-hosted or web-based solution
- removing watermarks would violate the terms of service of your AI provider
