rgx.tools

rgx.tools is an online tool for developers that turns a plain-language description into a ready-to-use regular expression. Instead of manually assembling tokens and flags, you describe what you want to find or validate in a string.

Generate regex from text

Type a request in natural language—for example, “find all phone numbers” or “validate an email.” The tool (based on GPT-3.5 Turbo) generates a matching regular expression and shows the result. This can lower the learning curve for regex and save time for experienced developers.

Language-specific output

The generator is designed for use across common programming environments, so you can see how the expression should look in your target language:

• JavaScript
• Python
• Java
• C#
• Ruby
• PHP
• Go
• Rust
• Kotlin
• Swift
• SED

Examples and editing

rgx.tools includes built-in examples and templates you can reuse or learn from:

• URLs with http/https
• Dates in MM/DD/YYYY format
• Phone numbers
• Password validation
• Hex color codes

You can also edit the generated regex manually before using it in your project.
