PERRY, AN ON-DEVICE AI TUTOR Full Access adds Perry, a tutor model that runs on your device (an optional download, roughly 2.7 GB over Wi-Fi). Ask Perry why an answer is wrong or get coaching on free-response strategy — the conversation never leaves your phone, because there's no server to send it to. FULL ACCESS A single one-time purchase, Full Access, unlocks every subject's full question bank, unlimited mock exams, Perry, and AI-assisted FRQ scoring. No subscription, no recurring charge. Schools and groups issued an access code can enter it in Settings instead of purchasing. HONEST ABOUT WHAT IT IS Perry is a study tool. Its FRQ feedback — whether self-scored against the rubric or AI-assisted — is an estimate meant to guide your practice, not a substitute for your teacher's grading or the real exam.
