Curio teaches you how AI really works, in plain English, a few minutes at a time. Then it asks you to prove it, and gives you a credential anyone can verify. LEARN IN MINUTES A DAY Follow a path of short lessons, drawn as a wire of beads you light up one by one. Every idea comes three ways: plain English, what it means for business, and how it works under the hood. Pick the depth that fits you. - Understand: what a large language model is, tokens and context, embeddings, agents and tools, retrieval, evaluation, safety and limits. - Apply: prompting well, choosing the right model, setting up your AI, writing and real work with AI, and using it safely. - The Operator Method: a practical way to put AI agents to work. A TUTOR IN EVERY LESSON Ask anything while you read. The tutor knows the lesson you are on, answers at your level, and stays on topic. REMEMBER WHAT YOU LEARN Quick checks after each lesson and spaced review bring ideas back just before you would forget them. Optional reminders on your iPhone keep the habit going, and your streak counts on your own local day. PROVE IT When a path is done, take the Mastery Check: a demanding exam graded against a published standard. Go further with Doctor Proctor, an oral defense where you explain your reasoning and hold up under follow-up questions. Or earn the Applied AI Practitioner credential by submitting a real piece of work. A CREDENTIAL ANYONE CAN VERIFY Every credential has a public verify page and a unique number. Add it to your LinkedIn profile in two taps, save the credential image to Photos, or send the verify link to anyone who asks. Credentials follow the Open Badges 3.0 standard, and the first 1,000 Gold credentials carry a founding number. CURIO KEYS Keys are guided prompt builders for real tasks, from emails and meetings to analysis and strategy. During launch, all 25 are free on every device signed in to your account. WHAT CHANGED IN AI TODAY Short, sourced posts from the Curio Team: the development that matters, a method you can use, and one topic explained properly. Every post cites its sources. HONEST BY DESIGN No account is needed to start. Before the first AI feature, Curio asks your consent to send your text to Anthropic, our AI provider, and you can keep reading without it. You can delete your account and data from Settings at any time. Credentials are free during launch, and a credential you earn now stays yours. Curio is for learning. Credentials show what you demonstrated in Curio and are not accredited qualifications.
