Hate Regex? This Free Tool Writes It for You
Hey HN, As an afternoon project, I created a simple tool that generates regex expressions from plain text using GPT-3.5. It's designed to help anyone who needs to quickly create regex patterns without manually writing them. Already posted this last week, but I did some QOL improvements & fixed minor bugs I found.

In plain words
This tool generates regular expressions from plain text descriptions using GPT-3.5, eliminating the need to write regex code manually. It is designed for developers and technical users who need to create regex patterns quickly. The tool accepts natural language input and outputs corresponding regex expressions, making pattern creation more accessible to those unfamiliar with regex syntax.
