KinetStudy

KinetStudy is an AI homework-grading assistant designed for parents. Take a photo of your child's homework, and AI reviews it question by question with explanations — wrong answers are automatically added to a mistake notebook, organized by subject, ready to redo anytime. 【Key Features】 • Photo Grading Snap a photo of homework and AI identifies each question, marking it right or wrong with explanations and knowledge-point context. Covers the main elementary school subjects: Chinese, Math, and English. • Mistakes Auto-Saved to the Notebook Wrong answers no longer stay scattered on worksheets. Grading and archiving happen in one step — mistakes are automatically organized by subject and knowledge point for easy review later. • Redo Anytime Mistakes aren't just collected for show. Redo them whenever you like: answer correctly and they leave the notebook; get them wrong again and they stay for another round of practice. • Follow-up Questions Curious about a specific question? Keep asking follow-ups based on the same photo — like discussing with a teacher why an answer works the way it does. • AI Tutor Based on the pattern of your child's mistakes, the AI tutor highlights weak areas and suggests what to practice next. It doesn't replace real tutoring — but it helps parents stop guessing. • Learning Reports for Parents Review your child's practice by week or month: which knowledge points keep causing trouble, which have been mastered, and whether practice is consistent. See it at a glance instead of guessing from the homework pile. 【Privacy Design】 • Photos and homework data are sent directly from your device to the AI provider you configure. The developer never stores, forwards, or analyzes them. • BYO Key supported: connect your own AI provider key — you stay in full control of where your data goes. • All practice records and the mistake notebook are stored locally on your device. Nothing is uploaded to the developer's servers. 【Works Offline】 • The mistake notebook, redo, and practice features work fully offline — open the app and start. • Only photo grading and the AI tutor require an internet connection to call AI services (with your own key, free). 【Subscription】 • Free: photo grading, AI tutor chat, mistake notebook, redo, practice, and parent learning reports. Online AI features are powered by your own provider key (BYO Key) and are free to use. • Pro: unlocks on-device learning analysis — AI mistake analysis, personalized study suggestions, and weak-area tracking. These analyses run locally on your device and do not depend on any AI service. Subscriptions are billed through your Apple ID and can be canceled anytime in Settings → Subscriptions. No refunds within an active billing period, as handled by Apple's policy. 【Please Note】 • AI grading results are for reference only and do not constitute professional educational advice. • Real learning comes from daily practice. This tool saves you time, but it can't replace a parent's companionship. 【Feedback】 • Email: [email protected] 【Subscription Terms】 • Privacy Policy: https://phinn.github.io/KinetStudy/privacy.html • Terms of Use: https://phinn.github.io/KinetStudy/terms.html • Terms of Use (Apple standard EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
