Question 1

How does the Smart tutor work?

Accepted Answer

Every question has a pre-built Socratic walkthrough — Genie asks, you answer, and it branches to correct your exact mistake. Answer keys are cross-checked across multiple sources, so you never learn the wrong answer.

Question 2

Do I need a credit card to start?

Accepted Answer

No. Signing up gives you 7 days of full Pro with no card required. When the trial ends you return to the free tier, which is free forever. Paid plans are one-time payments with no auto-renewal.
