What Is RAG and Why It Matters
An LLM will answer with the same confidence whether it knows the answer or is making it up — and in production, a wrong answer delivered with conviction costs more than an honest "I don't know". Retrieval-Augmented Generation — RAG for short — attacks exactly this problem.
Written lessons, with examples and exercises. Your progress is saved automatically, so you can pick up where you left off.
Select a passage and it explains it, gives you an example or tells you why it matters. You can type or talk to it, in English.
Every lesson has its own quiz, with explanations for the answers: 311 questions across the course. The professor also summarizes the lesson and prepares review flashcards.
Once you complete the lessons and reach the minimum quiz score, you issue it from your account, with a unique number, publicly verifiable.
The AI Professor is included in your subscription, per-course access included, with a monthly fair-use limit. It is an AI system, not a human teacher, and its answers may contain errors; details in the Terms. See how the AI Professor works.
