Cloud-based writing assistants (Grammarly, QuillBot, Wordtune) monitor continuous keystrokes and store corporate drafts on their cloud servers. PrivacyScrubber's Writing Shield redacts confidential customer names and financial terms in local RAM before text is processed by writing optimization tools.

Keystroke Monitoring Defense & Draft Tokenization

Sanitizes executive communications, legal drafts, and customer emails in <2ms local memory before third-party grammar analysis.

● IN-PAGE SANDBOXED INTERCEPTION Intersects DOM input before network transmission. Evaluates regex in <2ms browser RAM.
● 3-LINE LOOKAHEAD STITCHING Automatically re-assembles entities split across linebreaks before tokenization.
● REVERSIBLE TOKEN MAP Substitutes raw PII with reversible tokens ([NAME_1], [ID_1]) for instant 1-click restore.
● ADMIN BLUEPRINT LOCK Enterprise policies deploy with [ENTERPRISE LOCKED] badge — tamper-proof for staff.

Eliminating Cloud Keystroke Vulnerabilities in Corporate Drafting

When executives write sensitive emails or legal drafts with browser writing extensions active, full sentences are transmitted to external servers for grammar checking. PrivacyScrubber's sandboxed extension ensures that confidential client names, merger valuations, and employee feedback are tokenized locally, preventing third-party writing tools from capturing corporate secrets.

Executive Email Drafting Workflow

  1. 1
    Copy or Paste Unsanitized Content: Executive drafts confidential reorganization email mentioning department names and specific compensation adjustments.
  2. 2
    Real-Time In-Browser Sanitization: The extension masks employee names into [EMPLOYEE_1] and salary figures into [COMPENSATION_1] in local RAM.
  3. 3
    Submit to LLM with Zero Cloud Exposure: Grammarly / QuillBot optimizes tone and syntax around the structured tokens without seeing actual personnel data.
  4. 4
    Instant Local Reversal (Contextual Reveal): Executive restores actual names locally via 1-click reveal before sending the final email.

Corporate Trade Secret & Confidentiality Protection

Preventing third-party writing assistants from caching unreleased corporate communications ensures strict confidentiality, following our AI Privacy Guides standards.

True Sync with Centralized Corporate Policies

Corporate rules for executive project names synchronize seamlessly across all browser tabs via True Sync architecture, matching PII protection basics and Zero-Trust AI frameworks.

Zero-Leakage Writing Audits

Verify that zero corporate communications or employee identities were captured by cloud writing tools, meeting GDPR/CCPA standards standards.

Latest Capabilities: Multi-Line Stitching & Local OCR

The PrivacyScrubber Chrome Extension features 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.
