Explain it to me: Select Explain it to me on any flashcard, key concept or quiz question you got wrong, or Ask the tutor on a subject. The tutor knows what you were looking at, including your answer to a quiz question.
Tutor: The tutor answers using only your notes, at the level you choose: Simple, Standard or Detailed. It may end with a quick question to check you understood. You can ask up to 50 questions a day (10 as a guest).
Voice: Ask by voice with the microphone button, where your device or browser supports speech (Chrome and Edge on the web). Your question is sent when you stop talking, and the answer is read aloud. If your notes don't cover a question, the tutor says so and labels any general explanation "Not from your notes".
