I needed to share a contract but black out all client names and amounts. Typed the list, every match was covered. Exactly what I needed.
The fact that redaction is structural — not just a painted overlay — was the key selling point for our compliance team. This is real redaction.
Redacted SSNs and email addresses from 80 pages of HR records. Case-insensitive matching caught every variation. Saved hours of manual work.
Used it to anonymize a research paper before peer review. The whole-word matching option made sure partial matches were handled correctly.
Our legal team uses this before discovery submissions. Running entirely in the browser means confidential documents never leave our network.
Blacked out patient names from clinical reports in seconds. The preview shows exactly which matches will be redacted before you commit.
