Describe what you want to match in plain English — get a working regex with live testing, visual breakdown, and multi-language code.
The most complete regex tool
Describe what you want to match or select a pattern from the library above.
An AI regex generator converts plain English descriptions into working regular expressions. Instead of memorizing cryptic syntax like `(?:[a-z0-9!#$%&'*+/=?^_`{|}~-]+)`, you describe what you want to match and get a ready-to-use pattern with explanation.
Regular expressions are incredibly powerful for text processing, validation, and search — but the syntax is notoriously hard to read and write. Our tool generates the pattern, explains each part, and includes a live tester so you can verify it works before copying to your codebase.
"Match a valid email address", "Extract all URLs", "Validate a US phone number" — write it naturally.
JavaScript, Python, PHP, Java, Go, Ruby — regex flavors differ across languages.
Provide sample strings that should match. This helps the AI generate a more precise pattern.
Global (g), case-insensitive (i), multiline (m) — select the flags you need.
Paste a test string into the live tester before copying the regex to your project.
