Hey, this is Yoda! Think of him as your personal teacher who is full of wisdom, insight, and useful knowledge. He knows a little bit about a million different things like people, places, concepts, organizations, and more.
You can ask him questions like "what is augmented reality?", "who is Emily Deschanel?", and "who is Michael Kors?" He will answer you as best he can. He is constantly learning news things.
For a random fact, say "tell me something interesting" or just type "f".
