Short answer

How can I redact emails and phone numbers using AI?

Your agent uses the Regex Toolkit to identify specific contact patterns and replace them with masks. This prepares your text for reporting or public sharing. You'll see the specific steps and prompts below.

The outcomes

Where your data lands.

The AI processes your raw text and delivers these specific results.

CLEAN TEXT

Ready for release

The AI returns text where all identified emails and phone numbers are replaced by masks. You get a version ready for distribution.

REDACTED DATA

Safe for reporting

Sensitive identifiers are stripped out, leaving only the necessary context. This keeps your reports private.

PATTERN MATCH

Accurate identification

The agent uses regex to find exact matches for contact info. It catches numbers and addresses that fit the defined patterns.

HUMAN REVIEW

Final verification

The AI does the heavy lifting, but you decide if the masking is sufficient. You maintain control over the final document.

The workflow

What your AI does when the text arrives.

The AI handles the pattern recognition and replacement so you don't have to hunt through lines of text.

  1. Scan text

    Your agent reads through the provided document to locate any strings that match email or phone number formats.

    mask_sensitive_data

  2. Apply masks

    The AI replaces every identified sensitive string with a placeholder mask to hide the original value.

    mask_sensitive_data

  3. Verify patterns

    The agent checks the masked output against the regex rules to ensure no sensitive data leaked through.

    mask_sensitive_data

  4. Deliver output

    The AI presents the sanitized text back to you in your chat interface.

FAQ

How this task behaves

  • 01

    Can the AI redact names or physical addresses?

    No. This tool is built to mask emails and phone numbers using regex patterns. It does not identify names or addresses.

  • 02

    Will the AI delete the original data?

    No. The AI generates a new, masked version of your text. Your original source remains untouched.

  • 03

    Does the AI decide which data is sensitive?

    The AI follows the regex patterns provided. It identifies what matches those specific rules, not what it thinks is sensitive.

  • 04

    Can I use this on a live database?

    No. You must provide the text or document content directly to the AI client for the tool to process it.

  • 05

    Do I need to write the regex myself?

    No. The tool is pre-configured to handle standard email and phone number formats automatically.
