Questions

What counts as an AI request?On Free, anything that uses AI — generating a quiz, asking the coach, transcribing your voice. Ten a month, reset on the 1st.
What happens when I run out?Studying carries on exactly as before. Reviews, flashcards and notes never stop — only the AI features pause until the next month.
Why tokens on paid plans instead of requests?So you're not counting. Two million tokens is far more than most people use in a month of coursework.
Can I cancel?Any time, from your account settings. You keep access until the end of the period you've paid for.
Do I lose my notes if I downgrade?No. Your topics, notes, flashcards and history stay put — the AI features are what change.
