FAQ
Common questions
Does the free quota reset every month?
No. Free is a lifetime quota: 1 AI plan, 10 generated lessons, and 50 AI chats. It is enough to try one complete learning plan.
What counts as an AI chat?
Clarifying a lesson, answering validation questions, and Q&A all count as AI chats. Viewing existing plans or lessons does not use quota.
Can I cancel anytime?
Yes. You can cancel anytime. Pro stays active until the end of your current billing period.
Will I keep my plans if I cancel?
Yes. Everything you've generated stays available. Quota only limits new plans, lessons, and AI chats.
How do I pay?
Through Stripe. We accept major credit and debit cards as well as Alipay and WeChat Pay, and you can get receipts or swap cards anytime from subscription management.
