Welcome. This is the home of Petr’s AI School: a series of weekly sessions for colleagues at OnSinch, Shameless and friends. No programming background needed. The goal is simple to say and takes a few weeks to reach: you open Claude Code, describe what you need, and get it done, whatever your job is.
Start here
- Mental models - the four ideas everything else builds on. Read this first.
- Choosing a client - terminal, VS Code or desktop app: pick your window, then install it with the guides.
- Your first session - the homework after lecture 01. Twenty minutes, any client.
- Roadmap - what we cover week by week.
- Lecture 01: Introduction to AI - the first session, slides included.
- Glossary - every term we use, explained in plain English.
Coming back after a while? What is new lists everything added since you last looked, newest first.
