Built by me, from scratch
Not a tool I resell. Not something I white-label. I designed it, wrote it, shipped it to the Chrome Web Store, and I still fix it when it breaks at eleven at night. Students, writers, hobbyists, people who got curious last week — if you type into ChatGPT, Claude or Gemini, it's for you.
You write a rough prompt. One click rewrites it into a better one, with little chips you can adjust — the tone, who it's for, what shape you want the answer in. Most people's prompts are fine in their head and vague on the page. This closes that gap.
One prompt, several AI models at once, side by side — with a built-in judge that scores them and picks a winner. You can disagree and vote yourself. It's genuinely fun, and it teaches you more about prompting than any article will.
I kept watching people type one lazy line into ChatGPT, get a mediocre answer back, and conclude that AI was overhyped. The tool wasn't the problem. The prompt was. But nobody wants to read a guide about prompt engineering — they want the better result now.
So I built the thing that closes that gap in one click, and then added the duel because the fastest way to learn what a good prompt does is to watch three AIs disagree about it.
Because it's the difference between someone who talks about AI and someone who ships it. PromptDuel is live, it has real users, and it breaks and gets fixed like any real product. Shipping something and then living with it teaches you things that reading never will — which is exactly what you're hiring when you hire me to put a system inside your business.
If you're deciding whether to trust me, that's probably more useful to you than a list of certifications.
PromptDuel is my own product, but the same hands build the systems I put inside other people's businesses. Tell me what you're trying to fix.
