Overview
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
