About WorkLens
Your data should never leave your hands
WorkLens is a PII detection and redaction engine that runs entirely in your browser. No server. No upload. No cloud. Your files are scanned, redacted, and downloaded without a single byte leaving your machine.
The Problem
You need to share a spreadsheet — but it contains names, tax file numbers, and phone numbers.
You could manually search and redact. For 10,000 rows, that takes hours and you will miss things.
You could upload it to a cloud tool. Now a third party has your sensitive data.
You could write a script. Now you need to maintain regex patterns for every country and ID format.
How WorkLens Solves It
Drop a file
CSV, XLSX, JSON, or XML. Up to 10 MB.
15 layers scan it
Regex, checksums, AI names, semantic headers — all at once.
Review detections
Each finding shows entity type, confidence, and source.
Download redacted
One click. PII replaced with labels. Original untouched.
What Runs Where
Every component of WorkLens runs inside your browser tab. Nothing is hosted, proxied, or relayed through a server.
Finds patterns like emails, phone numbers, and ID formats. Validates numbers mathematically.
On-device AI that recognises person names, organisations, and addresses. Downloaded once, cached for instant future use.
Understands what your columns contain by analysing headers against known data patterns.
Reads CSV, XLSX, JSON, and XML natively. Your data never leaves the browser.
Heavy work runs in the background so the interface stays responsive during scans.
15-Layer Detection Pipeline
Each layer is a separate module. They run independently and results are fused by confidence — no single layer can override another without evidence.
Greyed out layers are planned for future releases.
By the Numbers
Built For
Compliance Teams
Audit spreadsheets for PII before sharing with third parties. Cryptographic audit trail for every scan.
Financial Services
Banks, insurers, and regulated entities handling customer data. Mathematical validation for tax IDs and government numbers.
Legal Professionals
Redact client names, addresses, and identification numbers from discovery documents and case files.
Healthcare Providers
Detect patient identifiers, health insurance numbers, and personal details in clinical data exports.
Data Engineers
Scan datasets before loading into analytics pipelines. Catch PII that slipped through upstream processes.
Anyone With a Spreadsheet
If you have a CSV with names and you need to remove them before sharing — this is the fastest way.
