Synapsi vs Quizlet

Quizlet locked it behind Plus. Synapsi keeps review free.

Quizlet moved the study modes students relied on behind a paywall. Synapsi is free to start, keeps flashcard and quiz review free, and adds what Quizlet doesn't have at any price: an AI-judged Feynman teach-back and real mastery tracking.

Quizlet built the habit, then started charging for the parts that mattered. Synapsi keeps daily review free, and the thing that sets it apart is not the flashcards, it is proof you actually learned them.
