Questions

What is Curio?
Curio teaches how AI works in plain English, proves it with demanding exams, and awards verifiable credentials. The mission is to make everyone fluent in AI.
Is Curio free?
Learning on Curio is free and needs no account to start. Mastery Credentials are free during launch: pass a track's Mastery Check to earn a verifiable credential, and a credential you earn now stays yours.
What are the three depths?
Every idea is explained at three depths: plain English, a business lens, and the technical detail. You can switch depth in a tap, any time.
What is the Curio Mastery Credential?
A credential earned by passing a real exam. Silver is a structured Mastery Check graded with per-criterion evidence; Gold is an oral defense with an AI examiner. Both are graded server-side, never self-declared.
How is a Curio credential verified?
Every credential has a public verification page and a signed Open Badges 3.0 assertion, so anyone can check that it is real without contacting us.
What are the Curio guides?
The guides are where The Curio Team publishes short, sourced posts about AI: a Signal on the one development that matters, a Playbook with a hands-on how-to, and a Deep Read that explains a topic in depth. Every article cites its sources.
