“Underneath the hood, Study Mode is not a tool trained exclusively on academic textbooks and approved materials — it’s more like the same old ChatGPT, tuned with a new conversation filter that simply governs how it responds to students, encouraging fewer answers and more explanations. This AI tutor’s knowledge, therefore, more resembles what you’d get if you hired a human tutor who has read every required textbook, but then also every flawed explanation of the subject ever posted to Reddit, Tumblr, and the farthest reaches of the web. And, because of the way AI works, you can’t expect it to parse right information from wrong.” —ND
