Question 1

What regex flavors does the AI generate?

Accepted Answer

JavaScript regex by default, with notes for Python (re module), PCRE (PHP/Perl), Java, .NET, and Ruby when the pattern has dialect-sensitive syntax.

Question 2

Does it explain the generated regex?

Accepted Answer

Yes. Every pattern is broken down component by component — for example, explaining that \d{4} means 'exactly 4 digits' and [A-Z] means 'any uppercase letter A through Z'.

Question 3

Can I test the regex against sample text?

Accepted Answer

Yes. Paste sample strings and the AI will show which ones match, which do not, and explain why each result occurs.

Question 4

What types of patterns can it generate?

Accepted Answer

Email validation, phone numbers, URLs, IP addresses, dates, postal codes, credit card numbers, password requirements, file extensions, and any custom pattern you can describe in plain English.

Question 5

What if the generated regex does not match correctly?

Accepted Answer

Describe what is wrong — for example 'it also matches invalid domains' — and the AI will refine the pattern. Iterating 2-3 times usually produces a production-ready regex.
