Privacy infrastructure that runs entirely on your device
Redaction is only the beginning
Start Redacting
Choose your file format. Everything runs locally in your browser.
Redact CSV
Detect and redact PII in comma-separated files. Names, emails, TFNs, phone numbers — found and masked instantly.
Redact XLSX
Scan Excel spreadsheets across all sheets. Multi-sheet support with per-sheet detection and redaction.
Redact PDF
Open, preview, and permanently redact sensitive content in PDF documents. Pixel-level precision.
Redact JSON
Scan nested JSON structures for PII. Traverse objects and arrays recursively — detect sensitive values at any depth.
Redact XML
Parse XML documents including FHIR and HL7 healthcare formats. Namespace-aware detection with element-level redaction.
Why WorkLens
Three things no other redaction tool can claim — and you can verify each one.
Zero Network Requests
Open DevTools. Drop a file. Watch the Network tab — zero outbound requests. Your data never touches a server. Prove it yourself.
Mathematically Verified
Australian TFN, Medicare, and ABN numbers aren't guessed — they're validated using official checksum algorithms (mod-11, mod-89). False positives eliminated.
Cryptographic Audit Receipt
Every scan produces a SHA-256 hash that proves exactly what was scanned and what was found. Tamper-evident by design.
Prove It Yourself
No other redaction tool can pass this test.
Open Chrome DevTools (F12) → Network tab
Drop any CSV, XLSX, JSON, or XML file on WorkLens
Watch the Network tab — zero outbound requests
Your file never left your machine
On-device engine · 22 PII entity types · Checksum validation · Cryptographic audit trail

Three simple steps to redact locally in your browser.
Upload
Drop your CSV, XLSX, JSON, or XML. It stays on your device.
Scan & Redact
PII is detected using regex, checksums, and AI — then masked automatically.
