RedactLab - free, no upload, runs in your browser

Redact sensitive data before you paste text anywhere

RedactLab finds and masks emails, phone numbers, IP addresses, card-like numbers, URLs, and API tokens in logs, support tickets, error messages, and prompts - before you paste them into a chatbot, a ticket, or a public forum. The redaction runs locally; the cleaned text is yours to review before it goes anywhere.

The paste-into-an-AI habit nobody audits

The fastest way to debug an error is to paste the whole log into an AI assistant. The log contains customer emails, internal IPs, maybe a staging API key. Most of the time nothing bad happens - until the one time it does.

RedactLab sits between the copy and the paste. Run the text through it first and the AI still gets the structure it needs, without the identifiers it does not.

What gets detected

Review, then share

Automated redaction is a strong first pass, not a signature of trust. RedactLab shows the cleaned text next to the original so you can scan it before copying - the two-second review that catches anything a pattern missed.

Frequently asked questions

Which patterns can it detect?

Emails, phone numbers, IPv4 and IPv6 addresses, URLs, card-shaped digit groups, and common API key or token formats such as sk_live_... strings.

Can I edit the redacted text before copying?

Yes. The output is a normal editable text field - adjust anything, then copy or download.

Does it redact names or free-form addresses?

No. Reliable redaction of arbitrary personal names requires context a local pattern tool does not have. For structured secrets (emails, tokens, IPs), the patterns are deterministic.

Is my text uploaded for analysis?

No. Detection runs in your browser with regular expressions, offline-capable after load.

Why keep timestamps but redact phones?

Timestamps are needed to understand a log sequence and are rarely identifying on their own. Phone numbers, emails, and tokens are direct identifiers - those go.
