Aldiax teaches you to use artificial intelligence by working through real situations, not by memorising definitions. Five minutes a day. No theory you will have forgotten by tomorrow. HOW IT WORKS Every lesson is a handful of short exercises about something you will actually run into: asking for a piece of writing and getting what you had in mind, spotting that it has made a fact up, deciding what information you should never paste into it, or recognising when pushing further stops improving the result. Right or wrong, we always tell you why. Getting it wrong here carries no penalty: it is part of learning. FOUR SECTIONS · Knowledge: the skills that work today and will still work in a year. Giving context, iterating, verifying, setting limits. Free and complete. · Latest: what keeps changing in AI, turned into practice. Not so you stay informed, but so you know how to use it. · Vocabulary: the words everyone uses and nobody explains to you. API, prompt, token, RAG, agent. · News: what has come out in AI, in three sentences. Free for everyone. AT YOUR OWN PACE A streak that keeps you company without nagging, freezes for when life gets in the way, and a profile that shows you which skills you are strong in and which you are not. ALDIAX PRO The subscription gives you every capsule in "Latest", the full Vocabulary glossary and twice the lives. You can use Aldiax free for as long as you like: the full Knowledge path and the News are included at no cost. There are two plans: Aldiax Pro Weekly, one week long, and Aldiax Pro Monthly, one month. The price of each is shown on the subscription screen inside the app. The subscription renews automatically unless you cancel at least 24 hours before the current period ends. You can manage or cancel it any time in your App Store account settings.
