Regular expressions are powerful… but let’s be honest — they’re a nightmare to remember.
Every time I need a regex, I end up doing one of these:
Googling: “regex for email validation”
Copy-pasting from StackOverflow
Re-testing it 10 times until it works
Still not understanding what it actually does
After years of frustration, I finally decided to fix this problem for myself.
So I built a simple AI-powered tool that converts plain English into a working regular expression — instantly.
No memorization. No RegEx cheat sheets. No headaches.
The Problem: Regex is Unnecessarily Hard
Regex is:
Cryptic (^\d{10}$)
Hard to debug
Easy to mess up
Difficult to read later
But 95% of the time, developers only need patterns for:
Email validation
Phone numbers
Dates
Password rules
IP addresses
URLs
So why are we still memorizing symbols instead of describing what we want?
The Solution: Plain English → Regex
Now, instead of writing this:
^+?[1-9][0-9]{7,14}$
I just type:
“regex for valid Indian mobile number”
And the tool gives me:
The regex
An explanation
Example matches
You can try it here (free, no signup):

Real Examples
Here are real inputs that work beautifully:
Plain English Input What I Get
regex for email validation Full email regex
match date in DD-MM-YYYY Date pattern
exactly 4 digits PIN code pattern
IPv4 address format IP regex
strong password with symbol Password validator
Instead of memorizing patterns, I just describe my requirement naturally.
Why This Saves Me Time
This small change saves me:
10–15 mins of Googling every time
Countless StackOverflow visits
Trial and error testing
Mental energy
It also helps juniors & non-regex developers on my team.
Privacy First
Everything runs in the browser.
No prompts are stored.
No signup required.
You can use it as often as you need.

I’d Love Your Feedback
If you use regex often, I’d love to know:
What’s the most annoying regex you’ve had to write recently?
Drop it in the comments and I’ll test it in the tool for you
