No round-trip to a server. Every clean runs locally in your browser the moment you click.

Intercepts PII, API keys, and secrets before they reach ChatGPT, Claude, or Gemini. Every regex runs in a Web Worker inside your browser — zero bytes sent to any server.
Compliance heads-up: GDPR data minimisation, CCPA, HIPAA, and the EU AI Act all restrict sending personal data to third-party AI platforms. Redact before you prompt.

In-Browser
Engine
PII detection, PDF extraction and OCR all run inside your browser tab. Nothing is sent to a server — scanned-page OCR even uses WebAssembly (Tesseract.js) entirely offline.
No runtime network dependencies

Zero bytes of your prompt ever leave this tab. Open DevTools → Network and verify it yourself.

Under the hood
Drop any text — code snippets, emails, support tickets, SQL queries — into the editor. Works with anything you'd normally send to an AI.
A local regex + NLP engine identifies emails, phones, AWS keys, API secrets, SSNs, EU VAT IDs, German addresses, and 30+ other PII types across English, German, French, and Spanish — entirely inside your browser.
Every sensitive token is replaced with a labelled placeholder like [EMAIL] or [AWS_KEY]. Zero bytes leave your device. One click to copy.
Built for professionals who can't afford data leaks.
Paste server logs safely. We automatically strip IPv4 addresses, API keys, and other leaked credentials.
Anonymize contracts. We redact names, SSNs, phone numbers, and dates of birth.
Note: While we remove PII offline, always follow HIPAA guidelines. Our tool adds an extra layer of safety.
Clean up messy PDF scrapes. Fix line breaks, remove headers/footers, and format as JSON.
