Examzi is the AI tutor you talk to. Prep for the SAT and high school exams out loud and get instant, personal feedback like a real tutor, at a fraction of the price. It is built around Learning Out Loud, where students build understanding by explaining their thinking out loud in a two-way spoken conversation. Instead of rushing to answers, Examzi helps students talk through problems, question what does not make sense, and correct themselves in real time. Most study tools reward fast output. Examzi is designed to slow students down on purpose so misunderstandings appear early, before they turn into exam panic, weak foundations, or expensive last-minute tutoring. Alongside spoken learning, Examzi includes flashcards, practice questions, mock exams, study plans, whiteboard support, and progress tracking. These tools are there to reinforce understanding, not just memorization. Examzi supports students preparing for real academic pressure, including SAT prep, GCSE exams, A-Level exams, assessments, and demanding subjects across math, science, English, humanities, and more. What makes Examzi different: • Students speak their thinking instead of typing answers • Understanding forms before answers appear • Voice tutoring keeps reasoning active, visible, and testable • Whiteboard support helps students work visually while they talk • Flashcards, practice questions, and mock exams reinforce understanding • Progress tracking helps parents and students see learning develop over time Examzi is not a shortcut and it is not an answer generator. It is built for students who need to understand what they are doing, and for parents who care about real learning, not just fast answers. Examzi Pro is an optional auto-renewing subscription, bought by a parent or school. Payment is charged to your Apple Account and renews automatically unless cancelled at least 24 hours before the end of the current period. Manage or cancel anytime in your Apple Account settings.
