Anki vs Clozemaster
Side-by-side comparison of features, pricing, ratings, and alternatives.
Anki is a flashcard application built around spaced repetition, using an algorithm to schedule reviews so learners spend more time on challenging material and less on cards they already know well. It is free and open source on desktop (Windows, macOS, Linux), with source code publicly available on GitHub and an extensible add-on ecosystem built by the community.
Clozemaster is a language-learning platform built around the cloze fill-in-the-blank exercise format, where learners complete real sentences rather than isolated vocabulary flashcards. It covers more than 50 languages with over 170 language pairings, and uses spaced repetition to reinforce words learners have already seen. Learners can choose multiple-choice or typing modes, track progress by word frequency to prioritize the most useful vocabulary first, and the platform recently added grammatical sentence analysis. The core game is free to play, with an optional Pro subscription that unlocks advanced features for more serious learners, available on web, iOS, and Android.
