Privacy Redactor
Use AI on everything.
Expose nothing.
Privacy Redactor detects names, IBANs, addresses, and other personal data, and replaces them with structured placeholders before anything leaves your Mac. Available for the browser and for your documents.
The real cost
Every document you paste into AI
gets processed on their servers.
The moment it's sent, it lives on infrastructure you don't control. Breaches happen. Legal discovery happens. Employees with access happen. Model training is just one risk buried in terms of service you scrolled past. Your client's name. Their IBAN. The contract you haven't signed yet.
Their servers, their rules
Their infrastructure. Their retention policies. Their staff with access. Their legal jurisdiction. A breach is one scenario — and not the only one.
Hidden metadata
A PDF carries author names, edit history, GPS coordinates, and deleted paragraphs. You paste more than you see.
No taking it back
A leaked client name isn't an "incident." It's a phone call you don't want to make.
Safari Extension — free to start
Intercepts PII as you type into ChatGPT and Claude. Redaction happens in the browser, before the message is sent. Install and go — no configuration needed.
How it works
RedMatiq replaces sensitive values with structured placeholders. The AI gets identical context without the real data. When results come back, original terms are restored automatically.
Pseudonymization, not deletion
RedMatiq doesn't black out text. It replaces sensitive values with structured placeholders like [PERSON_1] or [ORGANISATION_2]. This preserves document structure and meaning while removing identifying details.
The AI understands relationships and context because placeholders are consistent and structured. "Sarah Miller" becomes [PERSON_1] everywhere — in every file, every chat, every export.
What the detection actually catches
A multilingual BERT model, running entirely on your Mac. No API calls, no cloud inference, no data leaving your device.
23 entities in a two-page contract
Drop a document and the on-device model classifies every entity it finds: people, organizations, locations, emails, phone numbers, IBANs, dates, insurance IDs, and more. Each entity gets a type label and a confidence score.
The model handles mixed languages in the same paragraph. A German address next to a French name next to an English email. No pre-configuration needed.
Your level of control.
Some days you want speed. Other days you want to review every entity. Privacy Redactor adapts to you, not the other way around.
Quick Mode
Drop a document, get a clean file. Auto-detect everything, apply pseudonyms, export. One step from raw to safe.
Review Mode
Review every flagged entity in the Privacy Inspector. Toggle individuals on or off, add manual redactions, adjust types. Your judgment has the final word.
Tune the confidence threshold
The AI model assigns a confidence score to every detection. Set the threshold lower to catch more edge cases. Set it higher for surgical precision. Adjust it per-dossier or per-workflow.
Work your way
Drag, drop, copy, paste, export. In both directions. Mac-native.
Drag and drop
Drag files from Finder into Privacy Redactor. Drag clean files out into ChatGPT, email, or any app. The Mac way.
Export clean files
Export sanitized PDFs or Markdown. Structurally new files. No hidden author names, no edit history, no GPS coordinates.
Copy to clipboard
Copy pseudonymized text and paste it directly into any chat window, email, or editor. No intermediate file needed.
Dossier management
Group related documents. Pseudonyms stay consistent across an entire case, project, or client. "Sarah Chen" is always [PERSON_1] in every file.
MCP Server. Your documents in any AI.
Privacy Redactor runs a local MCP server. Claude Desktop, Cursor, and any MCP-compatible tool can access your documents as context. Always redacted. Always local.
Documents as AI context
Instead of copy-pasting text, your AI assistant reads your dossiers directly through the MCP protocol. The content is pseudonymized in real time. The AI gets full context. Your original data stays on your Mac.
Works with Claude Desktop, Cursor, Windsurf, and any tool that supports the Model Context Protocol. No plugins. No browser extensions. Just a local endpoint that speaks MCP.
- Zero configuration: Toggle it on. Point your AI tool at the local endpoint.
- Live sync: Change a redaction in Privacy Redactor, the AI sees the updated version immediately.
- Multi-document: Expose entire dossiers as context. The AI can cross-reference between files.
Where redaction matters
From legal review to blind hiring, the workflow is the same. The data never travels.
AI analysis
Use Claude, ChatGPT, and other tools with confidential documents. Analyze contracts and reports without uploading client data.
Consulting
Share client documents with subcontractors and partners. Maintain NDA compliance without slowing down your workflow.
Legal
Redact contracts, briefs, and case files before sharing outside your practice. Hours of manual review become minutes.
HR & hiring
Create truly blind resumes. Names, addresses, and graduation years disappear. Reviewers evaluate candidates on skills alone.
Healthcare
De-identify patient records for research and consultations. Preserve clinical context while meeting data protection requirements.
Test data
Create realistic datasets without real personal data. Placeholders are consistent — [PERSON_1] stays [PERSON_1] across every file.
Full AI power. Zero exposure.
Use AI exactly as you do today — except nothing sensitive ever reaches the cloud.
