# My colleague wanted a nerdy, niche tool for his MacBook. Codex whipped it up in minutes. > Source: > Published: 2026-07-11 12:02:01+00:00 Every week in the AI Playground section of our [Tech Memo](https://www.businessinsider.com/subscription/newsletter/tech-memo) newsletter, we feature folks trying an AI tool, or sometimes I test stuff out myself. This week, we hear from Business Insider's star AI reporter [Stephen Council](https://www.businessinsider.com/author/stephen-council). He's been using OpenAI's Codex tool to build software stuff without using code. OpenAI [merged Codex with ChatGPT](https://www.businessinsider.com/openai-codex-chatgpt-app-releases-gpt-5-6-models-2026-7) this week, so this is good timing. *I adore the copy-paste tool. Every day, it saves me from misspelling names, misquoting sources, wasting time on rewriting… I could go on and on. It's quick and easy and basically perfect.* *This week, **Codex** made it better. I've long wanted a version of copy-paste that lets me store multiple strings of text at once, so I can copy something new without losing what I'd copied before. There are clipboard managers for this online, but they often cost money, or add a pop-up and additional clicks — exactly the slowdowns I don't want.* *I gave OpenAI's tool a 190-word prompt, and voila! Five minutes and 26 seconds later, Codex handed me my app.* *Now, I have 9 different copy-paste slots on my work MacBook. Command-c and command-v work as normal, that's slot one. But now I can keep additional names, quotes, and links at the tip of my tongue: cmd-c-2 copies text for cmd-v-2, cmd-c-3 ties to cmd-v-3, and on and on. The app hangs out on my menu bar, so if I want to see what each slot is storing, it's all a click away.* *Very satisfying. It's exactly the niche and nerdy case that **vibe coding** is good for.* *Sign up for BI's Tech Memo newsletter *[here](https://www.businessinsider.com/subscription/newsletter/tech-memo)*.
