Generate regex patterns from natural language descriptions
About AI Regex Generator
Generate precise regular expressions from plain English descriptions using AI — test them instantly in your browser.
How to use AI Regex Generator
- 1Describe what you want to match in natural language (e.g., 'email addresses' or 'dates in DD/MM/YYYY format').
- 2Click "Generate regex" and the AI will create a matching pattern.
- 3Review the generated regex expression and its explanation.
- 4Paste a test string into the test field to validate the regex against real data.
- 5Copy the regex to use it in your code or application.
Tips
- Be specific in your description — 'US phone numbers with optional country code' works better than just 'phone numbers'.
- Always test the generated regex with edge cases before using it in production.
- Use the test field to refine your description if the first regex doesn't match all your cases.
