I’m able to record lectures and it translates it into study questions and flash cards for me. Saves sooo much time! Studying smarter, not harder. Right up my alley. -- GreatKB, 2026-04-26 ### ***** "The real deal" Very impressed by the sleek and easy to use interface that is surprisingly useful. Enterprise tier worthy app -- Whoa g, 2026-04-26 ### ***** "actually so helpful" okay i was so skeptical about another AI study app but kibin actually delivers. uploaded my lecture recordings and PDFs and it spits out solid notes and quizzes in like two minutes. the explain mode is lowkey the best part. you have to put concepts in your own words and it tells you if you actually get it or not. saved me so many times this semester. worth the pro upgrade fr -- jeffwyr46, 2026-04-24 [View all Kibin reviews and detailed analytics on AppTail](https://app.apptail.io/signup?utm_campaign=ai-crawl&utm_content=reviews) ## Kibin In-App Purchases | Item | Price | |------|-------| | Kibin Pro | $139.99 | ## Kibin Available In - [United States](https://apptail.io/app/kibin-ai-study-buddy-tutor-QQFz/united-states) - [Belarus](https://apptail.io/app/kibin-ai-study-buddy-tutor-QQFz/belarus) - [Canada](https://apptail.io/app/kibin-ai-study-buddy-tutor-QQFz/canada) - [Chile](https://apptail.io/app/kibin-ai-study-buddy-tutor-QQFz/chile) - [Guyana](https://apptail.io/app/kibin-ai-study-buddy-tutor-QQFz/guyana) - [Croatia](https://apptail.io/app/kibin-ai-study-buddy-tutor-QQFz/croatia) - [Bulgaria](https://apptail.io/app/kibin-ai-study-buddy-tutor-QQFz/bulgaria) - [Jamaica](https://apptail.io/app/kibin-ai-study-buddy-tutor-QQFz/jamaica) - [Latvia](https://apptail.io/app/kibin-ai-study-buddy-tutor-QQFz/latvia) - [Malaysia](https://apptail.io/app/kibin-ai-study-buddy-tutor-QQFz/malaysia) - [Norway](https://apptail.io/app/kibin-ai-study-buddy-tutor-QQFz/norway) - [Singapore](https://apptail.io/app/kibin-ai-study-buddy-tutor-QQFz/singapore) - [India](https://apptail.io/app/kibin-ai-study-buddy-tutor-QQFz/india) --- ## About AppTail [AppTail](https://apptail.io) is a mobile app intelligence platform providing app analytics, ASO (App Store Optimization) tools, keyword tracking, competitor analysis, revenue estimates, and review monitoring for iOS App Store apps.
