Mastering AI — From Zero to Building Automations and Agents
You once dropped a question into the chat, got a generic wall of text back, and decided "AI isn't for me." It wasn't you — it was the vague prompt. Here you learn to ask properly: you paste a tested prompt, watch it happen on screen, and finish every lesson with a ready result in hand. No coding at all.
“Paste, test, decide. The AI drafts; the decision is yours.”

The lessons in this module are in production. Content is released on the scheduled date, and existing students get the notice.
Over 50 micro-lessons of 5 to 9 minutes. Each one hands you a ready-to-paste prompt, a one-screen cheat sheet and a result of your own.
What you get beyond the videos
Every lesson ships with material you will actually use — and every module opens with the full study kit.
Summary table with the prompts
Every micro-lesson ends with a table of tested requests, ready to copy, test and reuse in your day-to-day.
Each lesson's slide deck
The slides used in the video, to review the concept in minutes without rewatching the lesson.
Module workbook
In the first lesson of each module: the written material to read alongside the videos, with deeper coverage and examples.
Module study guide
Also in the first lesson: the guide that organizes your review and locks in the content before the next module.
How it works — and what it will cost
A 100% online, self-paced course. You watch on your phone or computer, whenever it fits your week.
100% online, at your pace
Lessons of 5 to 9 minutes. On your phone in the bank queue or on your computer after dinner — however it fits your week.
Every lesson, a ready result
You paste a tested prompt and finish with something done, on your real task. It's not watch-and-take-notes: you do it together.
A living course, not an old video
AI changes every week. The course is reviewed against the official source and the list of what changed stays visible to you.
The investment will be announced at launch. Still no date and no buy button.
Those on the interest list hear first — and with the founder rate. Modules 1 to 5 run on the free Claude account; from Module 6 on (automations and agents), Claude requires its own paid plan, billed by Anthropic — not by OPEX.
