Eigen

Eigen is a personal AI tutor for students who need to actually understand the material, not just get an answer.

Bring what you are stuck on: a homework problem, lecture slides, a textbook chapter, a practice exam, or just a typed question. Eigen reads it in seconds and builds a real lesson around it. It teaches on a whiteboard, drawing the diagrams, writing out the equations and working through the examples step by step, while explaining everything out loud in a natural voice.

The difference from a chatbot is that Eigen teaches the way a good tutor does. It checks that you followed before moving on. It asks you to try the next step yourself. If you get lost, you interrupt by voice or by typing and it reroutes the explanation to the way you think, until the concept clicks.

It covers every subject: calculus, statistics, physics, chemistry, organic chemistry, biology, anatomy and physiology, pharmacology, economics, law, languages and more. Students use it to keep up with a semester, prepare for exams like the MCAT, NCLEX and LSAT, and catch up on the lecture they did not follow.

Eigen is free to start with no credit card. Paid plans add more lesson time for students who use it every day. There is also a family plan for parents who want their kids to have a patient tutor on call, with a dashboard showing what was studied.

Eigen works in the browser on any laptop or phone. No installation, no setup. Open it, drop in your material, and start the lesson.
