Frequently asked questions
What's the best AI for generating a regular expression?
ChatGPT and Claude are very reliable at turning a description into a correct regex, with an explanation of each captured group. GitHub Copilot and Cursor are handy when you want to generate it directly in your code.
Can AI explain an existing regex?
Yes: paste it into Claude or ChatGPT to get details of each part. Cursor and Windsurf (Codeium) do the same directly in the editor, with the context of your open file.
