Frequently asked questions
What does the output include besides the pattern?
The regex pattern itself, which flags to use, a plain-English explanation, 3 example strings that match, and 2 that don't — so you can sanity-check it immediately.
Is the regex guaranteed to be correct?
No — always test it against real sample data before relying on it in production, especially for anything security-sensitive like input validation, since AI-generated patterns can miss edge cases.
Can I ask for patterns in a specific regex flavor?
You can mention it in your description (e.g. 'PCRE' or 'JavaScript regex'), and the AI will do its best, but it doesn't guarantee flavor-specific syntax unless you're explicit.
