Welcome to danoh.com

danoh.com is a retro operating system experience powered by AI. Describe any application you want, and it gets generated on the fly, right inside a Windows 98-style desktop.

How it works

1. Click Start > Run
2. Describe the app you want: "paint app", "calculator", "snake game", anything
3. The AI generates a fully functional HTML/CSS/JS application in seconds
4. It opens in a draggable, resizable window on your desktop

How AI app generation works goes under the hood: how a sentence becomes a working program in three seconds, and where the model takes shortcuts you would never notice.

Fix & Iterate

Found a bug in a generated app? Click the ? button on any app window to open the Fix & Iterate chat. Describe what's wrong, and the AI developer fixes the code and updates the app live: no reload needed.

What can you build?

Anything that runs in a browser:

• Games: chess, snake, tetris, minesweeper
• Productivity: calculators, timers, todo lists, note-taking
• Creative tools: paint apps, pixel editors, music sequencers
• Data tools: charts, unit converters, JSON formatters
• Fun stuff: quote generators, fortune tellers, trivia games

If it runs in a browser, Run can probably fake it in thirty seconds.

The tech behind it

danoh.com is built with:

• Next.js 16 + React 19 for the frontend
• Anthropic Claude for AI-powered app generation
• 98.css for the authentic Windows 98 aesthetic
• Docker + Traefik for deployment
• PostgreSQL for session management

"The future of yesterday": every app you generate feels like discovering a lost program from an alternate reality 1998.

More to come. If something you generate breaks, tell the AI that built it: that's what the ? button in the title bar is for.
