Keet

Keet is a personal learning platform available on iOS that uses AI to generate interactive courses on virtually any topic. Backed by YCombinator, the app lets users create structured, Duolingo-style courses complete with explainer videos, quizzes, and games — covering everything from Topology and Quantum Physics to the History of San Francisco.

What It Is

Keet is an AI-powered mobile learning app that generates on-demand courses for any subject a user requests. Rather than browsing a fixed catalog, learners type in a topic and Keet builds a full course around it, with a structured roadmap, short video lessons, and interactive knowledge-testing games. The app sits in the category of personalized, generative education — combining the bite-sized lesson format popularized by apps like Duolingo with AI-generated content that can cover virtually any domain.

How Courses Are Structured

Each Keet course is organized into modules and lessons following a structured roadmap designed to build understanding progressively. A sample Topology course, for example, spans four modules — Abstract Set Theory, Topological Spaces, Continuity and Space Construction, and Topological Properties — each broken into multiple lessons of roughly four minutes each. This roadmap approach is intended to give learners a clear path from foundational concepts to deeper understanding, rather than a flat list of disconnected videos.

Learning Format and Games

Keet lessons combine explainer videos with several types of interactive games to reinforce retention. The game formats shown on the site include:

• Multiple Choice — pick the correct answer from four options
• Swipe — swipe-based knowledge checks
• Order — arrange items in the correct sequence
• Connections — link related concepts
• Custom — additional game types tailored to the course content

This multi-format approach mirrors the gamified learning mechanics that have driven engagement in consumer education apps.

Customization Options

When creating a course, users can customize the depth, complexity, and narration style of the generated content. This allows the same topic to be approached at an introductory or advanced level, and with different tones suited to the learner's preference.

Current Status

Keet is live on the Apple App Store under the name "Keet – Learn Anything." New users receive two free courses upon sign-up, after which additional courses require purchasing credits. The app is backed by YCombinator, signaling early-stage startup status with institutional support.
