Watermark Remover

Watermark Remover is a desktop application that erases watermarks from images using Google Gemini’s image-inpainting model. Draw a rectangle around the watermark, click Remove, and the AI rebuilds the pixels underneath — single image or batch.

What it does

• AI-powered inpainting — Google Gemini analyses the masked region and synthesises pixels that match the surrounding texture, lighting and colour.
• Region selection — drag-to-draw a rectangle over the watermark. The mask is precise to the pixel, so untouched areas stay untouched.
• Batch processing — pick multiple images, define the watermark region once on the first frame, and the same mask is applied across the whole batch.
• Before/after preview — original and processed images stack side by side; save only what you actually want to keep.
• BYO key, local-only — your Google Gemini API key is stored in Tauri’s plugin-store; nothing transits a third-party server.
• Cross-platform — Windows (x64), macOS (Intel and Apple Silicon), and Linux (deb / rpm / AppImage). Small binary, native dialogs.

Requirements

• Google Gemini API key — free to generate at aistudio.google.com/apikey
• Internet connection (the inpainting runs on Google’s servers, not on-device)
