Generate Regex Patterns with AI — Stop Guessing, Start Matching

Regex is one of those things that makes experienced developers feel like beginners. You know what you want to match. You just can't remember if it's \d+ or [0-9]* or some ungodly combination of lookaheads that makes your eyes water.

The Regex Struggle Is Real

Stack Overflow's most-viewed regex questions have millions of views. Millions. That's a lot of developers staring at cryptic patterns wondering why their email validation catches everything except actual emails.

Let AI Write Your Regex

The AI Regex Generator on AI Pass turns plain English into working regex patterns.

Just describe what you need:

• "Match email addresses" → gets you a production-ready email regex
• "Extract dates in MM/DD/YYYY format" → precise date pattern
• "Find URLs starting with https" → URL matching pattern
• "Validate phone numbers with country codes" → international phone regex

For every pattern, you get:

• The regex itself
• An explanation of how each part works
• Test examples showing matches and non-matches
• Common edge cases to watch for

Why AI Beats Regex Cheat Sheets

Cheat sheets give you building blocks. AI gives you the finished product for your specific use case. Tell it exactly what you need to match (and what you don't), and it tailors the pattern accordingly.

Need a regex that matches IPv4 addresses but NOT private ranges? Good luck finding that on a cheat sheet. AI handles it in seconds.
