Study agent
A study agent is an AI that does your study work for you. It does not just answer questions. It turns your material into flashcards and quizzes, keeps track of what you keep getting wrong, and tests you on it so you actually learn.
Most AI tools wait for you to ask something, then reply. A study agent goes a step further. You give it your material and it does the work of studying: it pulls out the key ideas, makes practice questions, and runs you through them. You are not just chatting, you are getting quizzed.
The useful part is that it watches how you do. Every question you miss, it remembers. So instead of drilling you on stuff you already know, it keeps coming back to the topics you keep tripping on. Over time it spends your study time where it actually helps.
Think of it less like a search box and more like a study buddy who reads the whole chapter, writes the flashcards, and then sits across from you and asks the questions.
Maria has a 90-page anatomy reader and an exam in five days. Instead of making cards by hand, she hands the reader to a study agent. It builds the flashcards and a quiz, notices she keeps missing the cranial nerves, and drills her on those every session until they stick.
