Eigen is a personal AI tutor for students who need to actually understand the material, not just get an answer.
Students upload their class materials and choose the support they need: preparing for a quiz, midterm, or final; learning a chapter or set of lecture slides; revisiting a lecture that didn’t quite click; or working through an assignment step by step. Eigen then teaches the material on an interactive whiteboard, explaining each concept aloud the way a patient tutor would, so learning feels engaging rather than like reading another textbook.
