I’ve been building LLM tooling for a small VC fund and found myself explaining the same mental model over and over to non-technical people around me: how a stateless LLM becomes a chatbot, how tool use works, what an agent is mechanically, and why context windows shape all of it.

I never found a guide that covered that full chain at the level I wanted, so I wrote one.

It’s nine short chapters, each building on the last. Deliberately simplified: the goal is a useful mental model, not a textbook.
