The idea

The Feynman technique says that if you cannot explain a concept in plain language, you have not learned it. The problem is that it needs a listener, and a listener who asks the right questions.

Sage is that listener. You explain a concept to Pip, and Pip asks you the question your explanation left open. Not a quiz. The specific gap in what you just said.

The Sage landing screen with Pip, the pixel-art study companion, and a Continue with Google button.
Sage. Pip does the listening.

Built with

React and TypeScript on the front, Supabase for accounts and progress. It tracks what you have explained well and what you keep skipping past.

[NEED FROM KOAH] Screenshots of the app behind the sign-in wall. I can only reach the landing screen without your Google login, and this page should show the part that does the work.
