Regex Tester vs Regex Generator
A Regex Tester lets you run a regular expression against sample text and see matches in real time. A Regex Generator (often AI-powered) helps you create a regex from a plain-language description. Use the tester to try and debug patterns; use the generator when you’re not sure how to write the pattern.
