RegexAI generates regular expressions from natural language descriptions and allows users to test existing regex patterns.

RegexAI is a free online tool that combines an AI-powered regex builder with a live regex tester. Users can describe their desired pattern in plain English, and the AI will generate the corresponding regular expression. Alternatively, users can paste an existing regex to test its matching behavior against provided text. The platform aims to simplify the process of creating and validating regular expressions, making it accessible for both beginners and experienced developers. It offers immediate feedback on regex patterns without requiring any signup or account creation.
