Pricing
The free plan is a complete way to study, not a trial. The engine, method selection, the stages, the memory model, adaptation and the calendar are all there and stay there. Paying adds personalisation and convenience on top — it does not unlock the method.

Kematra does not promise you a grade. It plans, and it adapts to what you record — the studying is yours. What it decides and why is set out on the transparency page, including the parts we invented.
