RedactAI: AI Document Redaction & Sanitization Tool
A production-grade, privacy-first AI document redaction and sanitization studio built for legal, financial, and healthcare compliance.
A production-grade, privacy-first AI document redaction and sanitization studio built for legal, financial, and healthcare compliance. Features coordinate-aware text extraction, multi-category PII detection (Personal, Financial, Confidential, Legal, Custom) using hybrid RegEx and contextual heuristic AI, synchronized dual-viewport Before/After document viewer with SVG dotted connector callouts, interactive rectangular/freehand area selection, live keyword and pattern search, granular approve/reject toggles, tamper-evident SHA-256 audit logging, privacy-safe AI summarization, local zero-server memory purge, and complete physical text layer excision from exported PDFs to defeat copy-paste (Ctrl+A) and binary stream extraction (The Clue Mandate).
- True Physical Redaction (The Clue Mandate): Sensitive text glyphs and tokens are permanently excised from both DOM content layers and PDF drawing streams (not merely obscured by black rectangles), preventing recovery via Ctrl+A copy-paste, pdftotext, or binary stream inspection
- Multi-Category Hybrid Detection: Detects names, physical addresses, emails, phone numbers, dates of birth, National Insurance / SSN, bank account numbers, sort codes, IBANs, fees, trade secrets, and governing court jurisdictions with 95%–99% confidence scores
- Synchronized Dual-Viewport Studio: Side-by-side Before Redaction view (with translucent highlights and SVG dotted connector lines to margin pills) and After Redaction Preview with synchronized pagination and zoom
- Granular Approval Lifecycle & Area Selection: Approve (✓), Reject (✕), or jump to items, with Draw Rectangle, Draw Freehand, and Select Text tools for arbitrary signatures, stamps, and paragraphs
- Live Pattern & Keyword Search: Search any keyword or custom regex pattern across all document pages with 1-click batch redaction
- Copy-Paste Security Verifier: Built-in automated security inspector testing DOM clipboard and byte stream extraction to certify 0 sensitive token leaks
- Privacy-Preserving AI Summary & Audit Log: Generates aggregate risk distributions without leaking raw secret text, accompanied by an immutable SHA-256 event log with PDF/JSON export
- Local-Only Processing & Memory Purge: Zero server telemetry, instant original file destruction, and automated temporary file cleanup
