Frequently asked questions
Everything you need to know about plans, billing, and learning on QuizzzX.
Can I switch between monthly and annual plans?
Yes. You can switch plans or billing frequencies at any time in your Account settings. When upgrading to annual, your remaining monthly credit is automatically prorated toward the annual total.
How do AI credits and monthly coins work?
Quiz generations, image labels and camera solves are unlimited on Pro and Pro+. They draw on your monthly AI credits (2,500 on Pro, 6,000 on Pro+), which cover the heavier AI work such as OCR on long textbooks and audio synthesis. Once the included credits are used up, you can keep going by spending coins.
Does my web subscription also work in the mobile app?
Absolutely. Your account is unified. Any subscription purchased here via Paddle unlocks full Pro or Pro+ access across the web app, iPad, iPhone, and Android apps immediately.
What happens to my decks and study plans if I cancel?
You will never lose your created notes, study materials, or review histories. If you cancel, your account returns to the Free tier at the end of your billing cycle. All your past flashcards and notes remain readable and reviewable.
What payment methods are supported?
