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 is processed locally — document content is never sent to our servers.
AI Detects PII Locally
Names, emails, SSNs, credit cards, medical IDs, and 23 supported entity types are found automatically using AI that runs entirely in your browser.
Download Redacted PDF
Sensitive data is replaced, masked, or encrypted. You download the clean file. No copy exists anywhere else.

Your Document Content Stays Private
AI detection, analysis, and redaction run locally in your browser. Document content is never transmitted to our servers — only account and usage management communicates with us.
Full PDF Redaction in Browser
Upload a PDF, detect PII with local AI, and download a redacted PDF with layout preserved. 8 built-in redaction methods, all running in your browser.
No Infrastructure to Manage
Open the app in your browser and start redacting immediately. AI processing runs locally, so there is no document pipeline to secure or maintain.
Built for Regulated Industries
Purpose-built redaction solutions for organizations that handle sensitive information under strict compliance requirements.
Legal
Attorney-client privilege protected. AI redaction runs locally so document content never reaches external servers.
Healthcare
HIPAA-compliant PHI de-identification. AI analysis runs locally so no PHI is transmitted to any server.
Government
Classified and sensitive documents processed locally. No external data transmission during redaction.
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, secure workflow without routing sensitive files through external systems. AI detection and redaction run locally in the browser — our servers handle only account and usage management.
Browser-First Experience
Upload, detect, review, and redact in one interface without moving documents off the device you are using.
Secure by Architecture
Document content never reaches our servers. Server communication is strictly limited to account authentication and usage management.
Transparent by Design
The split-plane architecture separates local AI processing from server-side account management, ensuring your sensitive data stays private.
