Cloud-based grammar checkers analyze every keystroke. Our Writing-Safe extension ensures that when you edit sensitive emails or patient letters in Grammarly or Quillbot, the personal data is hidden.

Native Editor Privacy

When a doctor writes a patient referral and uses Grammarly to check the tone, PHI is transmitted. PrivacyScrubber's native browser layer masks this data instantly, supporting the compliance benchmarks we define for AI Privacy Guides.

Frictionless Editing

Polishing PII protection basics with AI shouldn't require compromising confidentiality. Our extension masks sensitive entities in-situ, ensuring your drafts remain private, matching the security standards we set in our guide for Zero-Trust AI frameworks.

Zero-Trust Writing

By processing all redactions in the browser sandbox, no true names or IDs hit the grammar engine's servers. This alignment with GDPR/CCPA standards principles lets professionals write confidently and securely.

Latest Capabilities (v1.6.4): Multi-Line Stitching & Local OCR

PrivacyScrubber Chrome Extension v1.6.4 adds a smart 3-Line Name-Stitching Lookahead to capture names split across lines (e.g. Firstname MiddleInitial Surname) in scanned medical/clinical records, NDAs, and PDFs. It also supports Local Wasm OCR & PDF Sanitization to redact text from screenshots/PDFs offline, and Zero-Trust Session Sync (Argon2id + XChaCha20-Poly1305) to share rules peer-to-peer securely.
