Mercurius is an AI literacy tutor that helps you understand and use AI — clearly, critically, and responsibly. It's built on a simple idea: AI should help you think, not think for you. Instead of handing you answers, Mercurius guides you. Ask a question and it responds Socratically — with questions of its own that build your understanding — until you've genuinely grasped the idea. Only then does it unlock direct explanations. WHAT YOU CAN DO • Learn how AI actually works — models, prompting, bias, hallucinations, and how to tell good output from bad. • Practice four ways of thinking: Socratic (guided questions), Discussion, Debate (argue multiple sides), and Direct. • Share a photo — Mercurius can now see images you send and discuss them with you. • Check your understanding with auto-generated quizzes and a session report card. • Follow a curriculum of bite-sized AI literacy lessons. WHO IT'S FOR Students, curious learners, and anyone who wants to use AI well rather than passively. Trustworthy enough for educators, approachable enough for a first-time user. HOW IT'S DIFFERENT Mercurius isn't a homework-completion engine or a generic chatbot wrapper. Its comprehension gate, verification focus, and Socratic style are built to make you a sharper, more independent thinker — the opposite of outsourcing your reasoning. "Guided, not given." Mercurius is in active development — we'd love your feedback.
