SaiTutor
Snap a problem, see every step
Free · In‑App Purchases
Snap a photo of any problem. Your AI tutor works through it step by step on a blackboard — and explains out loud why each step works.
Not just the answer — a real explanation, the way a tutor would give it.
Stuck on a problem? Take a photo. Your tutor writes out the full solution step by step on a blackboard, explaining the reasoning behind each step out loud — like having a teacher sitting beside you, writing and talking you through it.
【KEY FEATURES】
■ Snap a Photo, Every Subject Covered
Math, physics, chemistry, biology, earth science, history, geography, civics, language arts, and English. Photograph problems straight from your textbook or worksheet — no typing required.
■ A Real Blackboard, Not a Wall of Text
The solution appears step by step, not all at once. Equations are typeset in proper mathematical notation, and geometry problems get diagrams drawn automatically, so you can see exactly what's happening at every stage.
■ Voice Explanation, Perfectly in Sync
The narration follows the blackboard as it's written. Watch the equation, hear the reasoning — pause or replay any step as often as you need.
■ Your Complete Study History
Every question and explanation is saved for later review. Create multiple learner profiles, so families with more than one student can share a single account.
■ Multilingual Support
Set your interface language and explanation language independently. Available in English, Traditional Chinese, Japanese, Korean, and more.
【WHO IT'S FOR】
・Students stuck on homework who need the reasoning explained
・Anyone who wants to understand the process, not just copy an answer
・Learners reviewing specific problem types after class
【SUBSCRIPTION PLANS】
Three plans — Scholar, Honor Student, and Valedictorian — differing in how many questions you can ask each month. New users get a free trial to experience the quality of the explanations before deciding.
Payment will be charged to your Apple Account. Your subscription renews automatically unless auto-renew is turned off at least 24 hours before the end of the current period. You can manage or cancel your subscription in your device Settings at any time.
