AI for healthcare professionals, starting from square one
Most writing about AI assumes you already know what a model is, what a prompt does, and why anyone would want an agent. This is the version that assumes none of that — plain English, one idea at a time, written by someone who had to learn it the same way.
There's no separate AI newsletter — the posts are free here, and everything else arrives in one monthly email.

How to connect a folder to Claude or Codex
The step that turns an AI chatbot into something that does your actual work isn't a clever prompt. It's giving it a folder. Here's what that means, and how to do it in Cowork, Claude Code, and Codex — starting from never having opened them.
What to say when someone senior asks you about AI
There are three available answers. Two make you forgettable. Here's how to give the third one without pretending to be a technologist.
