What is regex.ai?
regex.ai is an AI-powered regular expression generator and solver created by Liberty Labs. The workflow is example based: you insert your text, drag the cursor to highlight one or more strings you want to find, and the tool works out a regular expression that matches them.
The demo on the site shows several agents, labelled A to D, each proposing a different pattern together with the matches it finds, so users can compare the candidates. Highlights can be removed again by clicking them.
The site presents it as a way to automate data extraction tasks and speed up workflows for developers and anyone who works with text patterns. Documentation is linked from the page. No pricing is shown on the homepage.
Pros & Cons
Pros
- Builds regular expressions from highlighted example text instead of hand-written syntax.

The site presents regex.ai as a way to automate data extraction tasks and speed up workflows. It targets developers and anyone who works with text patterns, such as people who regularly pull specific values out of logs or documents.

No deep syntax knowledge is needed for the basic workflow described on the site. You show the tool examples by highlighting text, and the agents propose patterns for you to choose from. Knowing regex still helps when you compare candidates or adjust a result, because the proposals are not described as guaranteed to fit every case. Test any pattern on your own text.

Yes. Highlights can be removed by clicking them, so you can correct your selection if you marked the wrong text.
