Look behind the AI and use it with confidence, at work and in life. - Levels 1–20 free - No account, no tracking - Sources for every claim ### How a level works Every level is small. You learn one thing, see why it matters, and try it yourself before you move on. #### Goal Each level starts with one clear goal, like “Make ‘salad’ the most likely next word.” You always know what you are here to do. #### Explain A short explanation comes first. It says what is going on and why it matters, in plain words, before you do anything. #### Try it Then it is your turn. You place word pieces and watch real probability bars move, so you see the idea work instead of only reading about it. #### Takeaway A short recap tells you what you did and what happened. Then you get a takeaway card with the one thing to keep. ### What you learn The first 20 levels are free. Together they are the chapter “The basics”. **The basics** You learn what a chatbot is and what it is not. You ask it well, check what it says, and keep private things out of it. 1. The next word 2. Nothing is looked up 3. Common is not correct 4. Check the one claim 5. Your first line 6. Leave it out 7. Same question, different answer 8. New topic, new chat 9. Pieces, not words 10. The whole loop 11. Sources that don't exist 12. No safe place 13. Today's news 14. Edit, don't rewrite 15. Follow up 16. Work paste 17. Advice you act on 18. Ask before you paste 19. One-minute check 20. The start you never typed **Eight more chapters** About 80 more levels follow, with the same loop. #### Prompts that work Ask for what you mean, for a work e-mail or a weekend trip. Follow up instead of giving up. #### Chatbots in your day Improve your own writing, get advice, find and check information, plan and learn. #### Rescue a bad answer Turn a wrong or useless answer around, and know when a fresh chat is the better move. #### The right tool, current facts Know when it can see today's news, and what free or paid really gets you. #### Trust, but check Spot made-up facts, numbers and sources before they reach your boss or your family chat. #### Safe and private Know what never to paste, how to anonymise, and what to ask about AI rules at work. #### The machine behind the chat See what the app adds around the model, like hidden instructions, memory and tools, and why answers change. #### AI that acts for you Hand a task to an AI agent safely. Set limits and spot hidden instructions. ### Who it's for For anyone who uses a chatbot, or is about to, and wants to know what it is really doing. You do not need to be technical. #### At work You paste a draft into a chatbot and wonder if you can trust what comes back. You are not sure what is safe to paste. You want a better first message. #### In life You plan a weekend trip with a chatbot. A relative sends you a surprising “fact” from an AI. You want to understand it well enough to explain it. ### Why you can trust it #### Sources for every claim Every claim in the course comes with its sources. You can open them and check for yourself. #### Step by step Each idea is explained in small steps: what is happening, why, and then your turn. #### Honest about limits We say what we do not know. We make no promises about what AI will do for you. Who writes it, how AI helps, and how every claim gets its sources. ### Free and full version **Levels 1–20 free** The whole chapter “The basics”, with the boss level and the finale. Free to learn. **The full version** Adds 8 more chapters, about 80 levels. It is a one-time purchase. - No accounts. No sign-up. - No backend. Your progress stays on your device. ### Extra packages Besides levels 1–20 and the full version, there will be extra packages: specialised learning paths for one field. They are separate from the main course. #### For developers First package A learning path for people who build software with AI coding agents. It is written by a technical lead developer. - How an agent works: requests, tokens and context - Steering it: clear tasks, plans, tests and project instructions - Working safely: permissions, sandboxes and untrusted content - Delegating: helpers and reusable skills - Going further: loops, cost and checking results #### More packages to come Packages for other fields will follow, one at a time. Each one goes deeper into a single area. Like the whole app, the packages are coming soon. The topics may still change. ### Questions **Do I need to know anything about AI first?** No. Level 1 starts from the beginning: how a chatbot guesses the next word. New terms come with a plain-word explanation. **Do I need an account?** No. There are no accounts and no sign-up. **Is my data sent anywhere?** The app has no accounts and no backend. Your progress is stored on your device, and it stays there. **Is it a game?** It is a course you do, not only read. Every level has something to try. Level 10 is a boss level and level 20 is a finale. The point is that you understand, not that you score. **Which devices does it run on?** It is made for Android and for your browser. **How long does a level take?** Levels are short. Each has one goal, a short explanation, one thing to try, a recap and a takeaway card. **Who writes the content? Does AI write it?** The author is responsible for the content. AI helps with drafting and checking, and the author reviews it. Every claim cites a source. **Will there be courses for my field?** That is the plan. The first extra package is a learning path for developers. More specific packages for other fields will follow. They are separate from levels 1–20 and the full version. **When is it available?** Soon. We have no date yet. For now the button says “coming soon”. When the app opens, the button changes. ### Ready to look behind the AI? Levels 1–20 are free. ## How this course is made ### How this course is made You should know where a lesson comes from before you rely on it. Here is how we work, in plain words. #### Where the content comes from Every claim in the course points to a source. You can open that source and read it yourself. - We rely on primary documentation of AI providers and on recognised courses. - We do not use rumours, forum posts or our own memory as proof. - Each lesson explains its claim step by step, so you can follow the reasoning and not only the result. #### How content is checked A lesson goes through three steps before it is part of the course. ##### Draft A lesson starts as a draft with its claims and the sources behind them. ##### Source check Each claim is compared with its source. A claim without a source does not stay. ##### Author review The author reads the lesson and decides whether it goes in. #### The role of AI - AI helps with drafting and with checking sources. It is a tool, like a spell checker, only more capable. - The author reviews the result and is responsible for it. Nothing goes into the course unchecked. The author is still reviewing all levels personally. This review is ongoing. #### What we do not claim - No AI provider or other organisation endorses this course. - We give no guarantee that an AI tool behaves tomorrow as it does in a lesson. Tools change. - The course teaches how to use AI with care. It is not legal, medical or financial advice. #### Found a mistake? Please tell us. We check every report and correct what is wrong.
