Free tool

Redact PII from any text, without uploading it anywhere.

Paste an email, a support ticket, a contract clause. This tool finds and redacts personal data before you send it to an LLM, a colleague, or a screenshot. Everything runs in your browser. Nothing is sent to Ciralgo.

Why this is safe

Your text never touches our servers.

Runs in your browser

The redaction logic ships as JavaScript. When you paste text, it stays on your machine. No API call, no upload, no logging.

Simple, auditable rules

We use well-known patterns for structured data, plus a Luhn check for cards and the 11-test for BSN. Open dev tools and you can read every rule.

Not a full DLP

This is a good sanity check before pasting text into a chatbot. For production data flows, the real answer is Ciralgo's server-side redaction and audit trail.

Want redaction at scale, with an audit trail?

Ciralgo redacts every LLM request from your team on the fly, logs what was seen, and keeps everything inside the EU. Compliance-grade, not clipboard-grade.
