Hi HN! We’re Zack and Tommy, the co‑founders of Keet (YC S24), building a mobile app that generates courses on any topic. The app delivers short videos for explanation and games for reinforcement, mirroring a real curriculum to help learners progress over time.

Tommy and I met in a linear algebra class and spent four years taking classes together, forming a friendship built around learning new things. In school, curriculum designers deliver content and assessments; we found that structure frustrating and wanted a friction‑free way to start learning.

Keet gives users a custom starting point and sequences lessons logically. When you create a course, we ask about difficulty, depth, and intent, then categorize it using Biglan quadrants (Hard‑Pure, Hard‑Applied, Soft‑Pure, Soft‑Applied) to tailor instruction and examples. We also use Manim for math visualizations and Remotion for animated processes.

The beta is live on TestFlight; every user gets three free course generations with code “KEETHN”. After that, a monthly subscription will provide credits, similar to Suno. We’re improving personalization, generation speed, and interactive assessments, and welcome feedback from early adopters.
