AI-powered regex generator with real runtime validation. Describe what you need, get working patterns instantly. Built-in ReDoS security scanning catches vulnerabilities like the one that crashed Cloudflare in 2019. Smart optimization explains and improves your patterns. Code export ready to copy-paste. Test against real runtimes, not simulations. Currently supporting three languages with more coming. Stop wrestling with cryptic syntax and start building. 👉 chatregex.com




ChatRegex — Stop Googling "regex for email" every damn time
Look, writing regex is annoying. We all do it.
You need to validate a phone number? Extract URLs from text? Copy-paste from some blog post and hope it works. Then spend 20 minutes debugging why it matches things it shouldn't.
I built ChatRegex because I was tired of this dance.
What it actually does
Describe what you need in plain English. AI generates the regex. You test it right there. Done.
Currently supports Ruby, Python, and JavaScript. We're adding Go, Java, and PHP next — hit me up in the comments if you want a specific language prioritized.
The things that matter
Real runtime validation — Your pattern actually runs in Ruby/Python/Node, not some browser simulation. You see exactly what matches, what doesn't, and any named capture groups.
Clear explanations — Paste any regex and get a breakdown of what each part does. Finally understand patterns before you use them.
ReDoS security scanning — Remember when Cloudflare went down for 27 minutes in 2019 because of a bad regex? Yeah, we catch that stuff. The scanner analyzes complexity, finds attack patterns, and tells you how to fix it.
Smart optimization — AI suggests improvements for performance and readability. Explains what your regex actually does in human terms.
Code export — Copy-paste ready code for your language. No more "wait, how do I use named groups in Python again?"
Who's this for?
Honestly? Anyone who touches text processing.
- Backend devs doing data validation
- Frontend devs handling form inputs
- Data people parsing logs
- QA engineers writing test assertions
- That person on your team who always gets assigned "the regex tasks"
If you've ever stared at /^[a-zA-Z0-9._%+-]+@[a-zA-Z0-9.-]+\.[a-zA-Z]{2,}$/ and thought "I have no idea if this is right," you're the target audience.
