I'm James Perrotta, and I build and run Thought Pantheon.

I'm a data scientist. I build measurement systems, and my background is in natural language processing, psychometrics and industrial-organizational psychology. In short, I do assessment for a living.

I built Thought Pantheon for one job: making sure you understand what you learn, and that you keep it.

Marking a written answer fairly is a measurement problem, and I designed the marking here. Every question has a few key points, set before you answer. Your tutor, an AI, says which ones your answer covered. The app works out the mark from that, the same way every time, and shows you which points counted.

It is new, so I'm letting in a small group of early learners first. Payments are still in test mode, so no real card can be charged yet.

You do not have to take my word for any of this. The best way to judge it is to see it. The sample lesson shows the demo lesson's real questions and marking, and How it works explains every step.
