Rgx Tools is a free AI-powered tool that converts plain-language descriptions into clean, readable regular expressions, complete with code examples.

Rgx Tools is a free AI-powered tool for creating and editing regular expressions, developed by Amir Mendelson. It runs on OpenAI’s gpt-3.5-chat (GPT-3.5 Turbo) model and generates regex patterns from plain-language descriptions, producing expressions that are efficient and easy to read.
You describe the pattern you need — matching website URLs, phone numbers, or specific date formats, or validating email addresses, passwords, and social security numbers — and the tool returns the matching regex along with a code example showing how to use it.
The tool can generate regexes to:
Its clean, readable output simplifies a process that is often error-prone when done manually.
Rgx Tools suits anyone who works with regular expressions but wants to avoid writing them by hand:
Visit rgx.tools, describe the pattern you need in plain language, and the AI generates an efficient, readable regex matching your description, along with a code example demonstrating its use.
Rgx Tools doesn’t offer custom regex controls, advanced user settings, annotation features, or customizable code examples, and it doesn’t support multiple languages. Even so, it provides a streamlined way to create regexes that are both efficient and easy to understand.
