Redact Sensitive Data
Without Trusting a Server
How It Works
Three steps. Everything happens on your device. Nothing is uploaded anywhere.
Upload Your Document
Drop a PDF into the browser. The file stays on your machine — it is not sent to any server.
PII Is Detected Locally
Names, emails, SSNs, credit cards, medical IDs, and 23 supported entity types are found automatically — all inside your browser.
Download Redacted PDF
Sensitive data is replaced, masked, or encrypted. You download the clean file. No copy exists anywhere else.
See It in Action
Try the interactive playground \u2014 or open DevTools and watch the Network tab while you process a real document.
Built for Regulated Industries
Smart PII Detection
Instantly identify 23 types of PII including names, credit cards, SSNs, medical licenses, and crypto addresses using advanced NLP models.
Your Data Never Leaves Your Control
Documents are processed entirely on your device. Nothing is uploaded to any server — ours or anyone else's. This isn't a policy, it's the architecture. Verify it in your browser network inspector.
Full PDF Redaction in Browser
Upload a PDF, detect PII, and download a redacted PDF with layout preserved. Everything runs directly in your browser with 8 built-in redaction methods.
No Infrastructure to Manage
Open the app in your browser and start redacting immediately. No backend setup, no server hardening, and no document pipeline to maintain.
Built for Regulated Industries
Purpose-built redaction solutions for organizations that handle sensitive information under strict compliance requirements.
Legal
Attorney-client privilege protected. Documents never leave the browser during redaction.
Healthcare
HIPAA-compliant PHI de-identification. No PHI transmitted to any server.
Government
Works on air-gapped systems. Full offline capability after first load.
Financial
PCI DSS data processing in browser sandbox. Credit card validation via Web Crypto.
Built for Privacy-First Workflows
PDF Redaction is designed for teams that need a fast, local workflow without routing sensitive files through external systems. Use it in the browser, keep data on-device, and verify the privacy model yourself.
Browser-First Experience
Upload, detect, review, and redact in one interface without moving documents off the device you are using.
Air-Gap Friendly
After the app loads, processing can continue offline for environments where network access is restricted.
Transparent by Design
Open source components and visible network behavior make the privacy guarantees easy to inspect and validate.
1. Open a document in the dashboard
2. Detect names, emails, IDs, and financial data
3. Review matches directly in the browser
4. Apply redaction, masking, or replacement
5. Download the cleaned PDF locallyThe Only Redaction Tool That Never Sees Your Data
Other tools require you to upload sensitive documents to their servers. We don't — and we can prove it.
