An AI tutor you can actually talk to
Luna asks questions out loud, listens to your answer, and explains what you missed — grounded in your own notes, transcripts, and study guides. Built on proven learning behaviors: self-explanation and active recall.
Why students prefer a voice-first AI tutor
You explain it back
Saying answers out loud forces real understanding — students who self-explain can score up to 36 points higher on post-tests.
Personalized to you
Luna pulls from your own Study Libraries: lecture transcripts, PDFs, Quizlet sets, class notes.
