Building LLM Arcade

I give away the guides, and build the things I'm learning on.

1,450 free guides and recipes for building real systems on a computer you own, plus open tools and a few side projects. Self-taught, still learning in public.

For agents

This site answers to machines, not just browsers.

Ask any page for Accept: text/markdown and it returns Markdown. There is an MCP server, an A2A agent card, WebMCP tools registered in the page, a published set of agent skills, and DNS records that point agents here before they fetch anything.

Writing

Essays and field notes on AI-assisted building.

Want to learn this, not just read about it?

I teach people to build with AI, live and screen-shared. Learn to code, use AI on your real job, or ship the thing you keep putting off. One-on-one or in a small group.
