A full set of free AI builder courses. No signup, no paywall. These are the same workflows we use to ship real products with AI, written up so you can copy them step by step.
Start with Claude Code basics, then go deep on MCP and building AI agents from scratch. Every lesson ships working code, not theory. Pick a track and start building.
