How Datablurai works

A privacy risk analyzer that scores your image before you share it — and offers one-click redaction. Every byte stays in your browser.

On-device pipeline

When you drop in an image we run a small chain of models and parsers entirely inside your browser: a WASM face detector, Tesseract.js for OCR, regex classifiers for email / phone / ID numbers, jsqr for QR codes, and exifr for GPS metadata. There is no server round-trip, no analytics on your image, no caching outside your tab.

What we detect

  • Faces+15
    WASM face detector spots faces in group shots and selfies.
  • License plates+15
    OCR + rectangle heuristics flag visible vehicle plates.
  • Email addresses+20
    Regex over OCR text finds inboxes hiding in screenshots.
  • Phone numbers+20
    International phone formats are matched on extracted text.
  • QR codes+25
    Decoded with jsqr — even a small QR can leak a lot.
  • ID numbers+50
    Country-specific patterns (e.g. TW national ID) carry the highest weight.

Risk scoring

Each finding adds its weight to a running total capped at 100. The total maps to a level that tells you, at a glance, whether the image is safe to share.

Low
0 – 30
Looks safe to share.
Medium
31 – 60
Consider redacting before posting.
High
61 – 100
Strongly recommend redaction.

Built for any device

Heavy work runs in a Web Worker so your UI stays responsive. Models lazy-load only when you upload the first image, and Tesseract workers are terminated when they are no longer needed.
