How does it work?
Your tutor
Create your account in a click, then connect the AI app you already use. It takes a couple of minutes.
Your tutor asks a few quick questions about you and what you already know, then recommends where to start.
Every lesson is a conversation. Your tutor checks your understanding, and this site keeps track of your progress.
You
What can I learn?
Your tutor
Courses go from first steps to advanced topics, in a recommended order.
Start from zero. What AI is, how machines learn, and what is really happening when you chat with an AI.
Work with AI coding assistants like a senior developer — know what they see, split work into tasks they handle well, review their code, protect your secrets, and keep tests and git as your safety net. The course works with any tool.
Keep an agent sharp over hours of work: treat the context window as a budget, compact history without losing the thread, keep memory outside the window, and delegate to sub-agents when it helps.
You
Why not just watch videos?
Your tutor
You ask questions, try ideas and get answers in your own words, at your own pace.
A short level check skips what you already know, so you start where it counts.
The courses and the code are open source, and you can download or delete your data at any time.
