Eigen

Eigen helps students understand coursework instead of just collecting answers. Upload lecture slides, a textbook chapter, a homework problem, a practice exam, or type a question. Eigen reads the material and builds a spoken lesson on an interactive whiteboard, drawing diagrams, writing equations, and working through examples step by step. Students can interrupt by voice or text, ask for another explanation, and try the next step themselves. It supports subjects including math, science, economics, law, and languages, as well as exam preparation.

Eigen runs in a browser on laptops and phones. It's free to start without a credit card; paid plans add more lesson time, and a family plan gives parents a dashboard of what was studied.
