Regex is brutal. AI writes it for you in seconds — but you should test every pattern.
7 min · Reviewed 2026
The big idea
Regex looks like cat-walked-on-keyboard nonsense. AI is genuinely good at writing it. But regex breaks in weird ways, so always test with real examples before shipping.
Some examples
Ask: 'Regex to match a US phone number in any format.'
Have AI explain what /^\w+@\w+\.\w+$/ does line by line.
Get AI to write a regex AND a list of strings it should and shouldn't match.
Ask AI to debug a regex that's not catching one weird edge case.
Try it!
Pick a string format you deal with (like a date or a username). Ask AI for the regex plus 5 strings to test against. Run it.
