In this Code Along Jr. episode, our host Kalani teaches you how to create an AI chatbot in Scratch! 🤖 Learn to create your robot’s brain 🧠 and teach your robot what questions to check for and how to respond to those questions! Also, if your robot doesn’t know the answer to a question, you’ll learn how to teach it more answers. At the end of the episode, you’ll have a fully functional robot to interact with!
