Pricing

A Course costs US$5, paid once. It’s priced at cost, since Apedia doesn’t aim to profit.

What a Course includes

One subject and its Mission: the Teacher interviews you about why you want to learn it.
Up to 20 Lessons written for you, each with verified Resources and a quiz.
Up to 100 questions to the Teacher across its Lessons.
A printable Reference sheet that grows with every Lesson you finish.

Once the Lessons or questions are used up, everything written stays yours to read. Another Course keeps you going on a new Mission.

Why it isn’t free

Every Lesson is written by an AI Teacher that costs money to run, and the price covers that.

Paying

You pay once for each Course, with no subscription. Polar takes the payment and sends your receipt. Sales tax or VAT may be added at checkout, depending on where you live.

Refunds

If your Course was never written, ask within 14 days of buying and you get your money back. The Refund policy has the details.
