Regem is an AI-powered web tool that generates regular expressions from natural language prompts and includes a built-in tester for immediate validation. Users simply describe what they need the regex to do—such as “match a 10-digit phone number”—and the platform returns a functional regex string. It also explains the logic behind the pattern and allows users to test it on custom text directly within the interface. This makes it ideal for quick regex construction, real-world application, and learning through experimentation. Whether you’re creating filters, validations, or search patterns, Regem offers a full-cycle regex workflow in one place.
