How credits work
1 credit = 1 AI explanation. You are only charged when you receive an answer — if a request fails, the credit is automatically refunded.
Free tier: Upon signing up with Google, you receive 5 credits once per Google account. These are for exploring AI Solve Quiz and do not renew.
PRO subscription: Pay $5/month via PayPal. At the start of each billing cycle, your PRO credit allowance resets to 300. Unused PRO credits do not carry over to the next cycle.
Add-on packs: $1 buys 50 credits as a one-time purchase. These stack on top of your PRO or free credits and never expire. Add-on credits survive PRO billing cycle resets.
Consumption order: When you use a credit, PRO-cycle credits are drawn first, then add-on credits.
Payments: All payments are processed securely via PayPal. Subscription auto-renews monthly; cancel anytime from the portal. Add-ons are non-refundable once credits are granted.
