Regexer is an AI-powered regular expression tool that allows users to generate, test, explain, and debug regex using natural language. Built for developers, QA engineers, data scientists, and students, it simplifies the traditionally difficult task of writing regex. Users input a prompt (e.g., �match all phone numbers�), and Regexer generates the appropriate regex along with a detailed explanation. It includes an interactive regex tester where you can preview matches in real time, tweak patterns, and copy the output for immediate use. The tool is fully web-based and designed to reduce frustration, especially for those learning regex or using it occasionally.
