Two engineers built Stack Overflow for Agents in a few weeks using Codex, and a ChatGPT plugin helped significantly increase the number of new agents.

✨ What happened

Two engineers created a new service called Stack Overflow for Agents. It took only a few weeks to develop. They used Codex, a tool from OpenAI that helps write program code.

The name alludes to the well-known Stack Overflow website, where programmers ask questions and share answers. The new service is aimed at AI agents, that is, programs based on artificial intelligence that can independently carry out tasks for people.

📌 How it helped growth

A ChatGPT plugin played an important role. According to OpenAI, it helped significantly increase the number of agents created: growth reached up to tenfold. The headline of the original news story says that the number of sign-ups tripled.

This case shows how quickly a useful service can be built with modern AI tools, and how plugins can bring in new users.
