Questions
What files work?+
The HTML export from your course site, PDF, PowerPoint (.pptx) and plain text. Scanned slides that are only pictures won't have enough text; paste the text instead.
Is it accurate?+
Each lesson is written from your slides and then fact-checked by a second AI pass that fixes wrong answers. It can still make mistakes, so teachers review lessons before publishing and anything that matters should be checked against your course material.
I'm in a teacher's class. Do I need to pay?+
No. Students study their teacher's class free while the teacher's plan is active. Everyone also gets one free lesson of their own, and Starter and Semester Pass let you build more.
Can I cancel?+
Yes, any time, from your account page. Your plan stays active until the end of the period you paid for.
