About this AI Regex Generator

Regular expressions (regex) are a compact and powerful way to match text patterns, but they can be confusing and difficult to write correctly. This AI Regex Generator is built to help you create accurate, production-ready patterns without memorising complex syntax.

Simply describe your requirement in plain English — for example, "match valid email addresses" or "extract phone numbers from text" — and this tool will instantly generate a clean and usable regex along with an explanation.

Why use an AI-powered regex generator?

• ✅ Saves time by eliminating trial and error
• ✅ Reduces regex mistakes and syntax errors
• ✅ Provides readable explanations for learning
• ✅ Works for beginners and professionals alike

Common use cases

• Email and phone number validation
• Extracting data from logs or files
• Verifying password formats
• Matching dates, URLs and file names
• Cleaning and filtering large text blocks

How to write a good prompt

To get the best results, be specific in your prompt. Mention what you want to match, any special conditions, and whether it should match the full string or part of it.

• regex for Indian mobile number starting with 9, 8 or 7
• match YYYY-MM-DD date format
• email validation excluding gmail.com

Tips & best practices

• Use ^ and $ for full string matches
• Prefer specific classes like \d instead of .
• Avoid overly greedy patterns like .*
• Always test your regex before production use

If you're new to regular expressions, this tool is a great way to learn by doing. Experiment with different prompts and observe how patterns change.
