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.
