On-device detection
Local models spot names, emails, phone numbers, and IDs without sending a single byte anywhere.
Redact personal data before it leaves your desk.
Do you use AI to write emails?
Every name, number, and address in your draft is exposed to the AI. PII GUI redacts them first—so the model never sees the real data.
Contract renewal
An everyday email—full of personal data. Hit Redact to clean it up.
PII GUI finds and redacts names, emails, phone numbers, and other personal data in your documents using local AI models—entirely on your device. Supports text, Markdown, and PDF files.
Perfect for contracts, medical records, HR files, support logs, and any document you need to share without sharing everyone in it.

Features
Redaction you can check, line by line.
Detection, review, filters, and export live together—so cleaning up a document never means juggling tools or trusting a black box.
Redaction that sticks
Export PDFs with sensitive text actually removed—not just covered with a box.
Review before you commit
Every detection is highlighted in place, so you decide what stays and what goes.
Custom regex filters
Add your own patterns for account numbers, case IDs, or anything the models can't know.
Supported file formats
Open text, Markdown, and PDF documents and export cleanly redacted copies.
No account required
Download the app and start redacting—no sign-up, no login.
How it works
From document to redacted copy, in three steps.
Everything happens in one window, on one machine—yours.
1
Open a document
Drop in a PDF or paste text. The local model downloads once and works offline from then on.
New document
2
Review detections
Personal data is highlighted in place. Toggle anything on or off, and add regex filters for your own patterns.
3
Export the redacted copy
Save a redacted PDF or text file with the sensitive content removed for good.
