It uses Meta’s Llama3 LLM model to generate Regex for pattern matching, text extraction, and data validation.

You describe what the Regex is used for, and the AI generates a Regex pattern, tests it, and improves it based on feedback until it achieves optimal performance. This process can make the Regex generated as accurate as possible.

How to use it:

1. Visit the MagicRegexGenerator website to get started.

2. On the main page, you’ll see several input fields. Let’s go through each one using an example of generating a regex for US phone numbers:

  • In the first field, type “US phone numbers”. This tells the AI what kind of Regex you need.
  • In the next field, enter “(555) 555-1234”. This is crucial as it forces the AI to generate a regex that matches this specific format.
  • Provide example strings that the Regex should not match. Leave this field empty if you don’t have any specific strings to exclude.
  • Add any additional information about the Regex you want to generate. For example, “Match a phone number with – and/or country code.”
