Free AI helps you get unstuck. Premium AI uses a stronger model that explains more clearly, writes better examples, and remembers the lesson you are reading. Ask as much as you like, up to a generous monthly limit.
Every premium question uses tokens: the lesson text we send along, your question, and the answer. A typical question is around 2,500 tokens. The free engine never counts.
Fox switches you to the free engine so you can keep learning. Your premium allowance comes back on the 1st of the month.
No. Questions go to the model provider only to produce an answer. We store token counts, not your conversations.
