The recommended route, and worth the extra step: copy this prompt into a top-tier AI — Claude, ChatGPT or Gemini — and it turns your settings into a complete, ready-to-install 404 page. Top-tier models produce a noticeably better, more polished page than any quick option.

What makes a Great 404 page
A great 404 page does two jobs in the same moment: it catches someone who just hit a wall, and it does it without breaking the brand or dead-ending them. Here are the twelve things the best ones get right.
404 pages done right
A handful of dead ends that became brand moments. Click any card to see it live. The first is the page that started all this, and CTO Jobs HQ was built start to finish with the generator on this page.
