Regex.ai

Regex.ai - Artificial Intelligence Regular Expression Generator is an AI-powered tool designed to help users craft, test, and refine regular expressions quickly. It offers an interactive interface to insert text, highlight matches, and generate corresponding regex patterns. Users can click on highlighted text to remove matches, aiding rapid iteration. The platform includes example datasets (emails and other patterns) and provides a solver-like experience to discover regex solutions for text extraction tasks.

How to Use Regex.ai

1. Insert your text into the workspace. You can paste large strings or blob data to search for patterns.
2. Highlight strings to find matches or use the tool’s highlighting to visually select candidate matches.
3. Generate or refine regex based on the highlighted segments. The AI suggests matching expressions; you can adjust until it fits your needs.
4. Click on highlighted text to remove it and observe how the regex changes in real time.
5. Test across multiple samples to ensure robustness (e.g., emails, domains, numbers).

Note: The tool shows example datasets (e.g., various email formats) to illustrate pattern discovery and regex generation.

Use Cases

• Extract email addresses from large text blocks
• Validate input formats (emails, domains, URLs, numbers)
• Build reusable regex templates for data cleaning
• Learn regex by visual interaction with real text

Safety and Privacy Considerations

• Avoid processing sensitive or personally identifiable information without proper authorization.
• Validate generated expressions against edge cases to prevent unintended data extraction.
