Welcome to danoh.com
A retro Windows 98 desktop where any program you describe gets generated by Claude in seconds. Here is what is running underneath.
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
- Click Start > Run
- Describe the app you want: "paint app", "calculator", "snake game", anything
- The AI generates a fully functional HTML/CSS/JS application in seconds
- 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
The only limit is your imagination.
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.
Stay tuned for updates. We're just getting started.
