Keet

Keet is an iOS app that generates personalized, interactive courses on any topic. A learner names a subject, and Keet builds a structured course with short explainer videos and game based exercises in the style of language learning apps. The company states it is backed by Y Combinator. Each course is generated as a roadmap of modules and lessons, with lessons running about four minutes, so material is learned in small steps. Every lesson contains videos and quizzes, and the games include multiple choice, swipe, ordering, connections and custom formats. Courses can be customized when they are created, with settings for depth, complexity and narration style. The home page shows example courses on subjects such as topology, quantum physics, the Big Bang, Mongol war tactics and the history of San Francisco and New York City. Keet is aimed at self directed learners who want a course on a niche subject that no existing curriculum covers. It is downloaded from the App Store, and an account is needed to start building courses. On pricing, the site says new sign ups receive two free courses, after which credits must be purchased to generate more. Credit prices are not published on the site.
