Regex.ai

Regex.ai is an AI service for generating and solving regular expressions. Paste your text, highlight a few target fragments (such as emails, numbers, or IDs), and the tool suggests a regex that matches the selected examples.

Generate regex from highlights

Instead of building patterns by hand, you mark the strings you want to match and Regex.ai proposes an expression that finds them. You can refine results by removing highlighted items with a click to reduce false matches and tighten the pattern.

Data extraction and regex debugging

Regex.ai is useful for practical tasks where regex is often needed but time-consuming to craft and test:

• Parsing and extracting data from raw text
• Cleaning and filtering logs
• Preparing datasets
• Automating repetitive steps in analytics and development

Once generated, you can immediately test the regex against your own text to validate matches and iterate quickly.
