Workflow
  1. Upload the PDF. Scans need OCR first (~5 MB WASM module, on demand) to detect text; this workshop doesn't bundle it by default — you can also paste text below to help detection.
  2. Paste a chunk of the text you want to check into the detection panel on the right; it picks out IDs / phones / cards / emails / addresses / IPs for review.
  3. On the PDF preview, drag a rectangle over each sensitive region; on export the area is opaquely redacted.
