Feyncard

Flashcard app using the Feynman technique with LLM feedback

Feyncard is a flashcard app that leverages the Feynman technique — a learning method where you explain a concept as if you’re teaching someone with no prior knowledge.

Users create flashcards, study them, and explain the concept out loud. An LLM then evaluates the user’s explanation and provides constructive feedback for improvement.
