MaskBeforeAI Upload Guard

About

MaskBeforeAI lets you mask sensitive areas in images and documents before they reach an AI platform. An interactive review dialog opens automatically when you upload, paste, or drop a file — so you can black out, blur, or pixelate private content before anything is sent.

Everything runs 100% locally in your browser. No data is uploaded to any server. No account required for the free version.

HOW IT WORKS:
1. Upload or paste a file on a supported AI platform
2. MaskBeforeAI opens an interactive review dialog
3. Draw masking boxes, use the brush tool, or use the eraser
4. Choose blur, pixelate, or black-box redaction
5. Click "Apply" — the masked file replaces the original before upload
