Quizlet is the most popular flashcard app in the world — but it paywalled its Learn mode and uses a proprietary algorithm. Forgetless gives you unlimited study sessions free, with FSRS v6 (the same open-source algorithm as Anki) and AI card generation included.

Quizlet paywalled their Learn mode — the feature that actually helps you remember. Forgetless gives you unlimited study sessions free, forever. Every review is scheduled by FSRS v6, the same algorithm trusted by millions of Anki users. The science shouldn't be behind a paywall.
Quizlet uses a proprietary algorithm that you can't inspect or verify. Forgetless uses FSRS v6 — an open-source algorithm backed by published research that personalizes your forgetting curve and optimizes review timing. It's proven to improve retention by up to 30% compared to older methods.
