Anki is a powerful, open-source flashcard program renowned for its effective spaced repetition system (SRS). It isn't a language course itself, but a highly effective tool for memorizing vocabulary, phrases, or grammar rules that you input yourself or download from shared user-created decks. Its high degree of customization allows for rich cards with audio, images, and cloze deletions. While its interface can be unintuitive for new users, its effectiveness for long-term retention is largely considered unparalleled for dedicated learners.
Readlang helps you learn a language by reading authentic content from across the web. As a browser extension and web app, it allows you to click on any word or phrase you don’t know on a webpage to get an instant translation. These translated words are automatically saved as flashcards for later review via spaced repetition. It is an exceptional tool for intermediate-to-advanced learners looking to transition to native materials and expand their vocabulary contextually, but it is primarily a reading and vocabulary tool with no speaking component.
Busuu offers well-structured courses that balance vocabulary, grammar, and practical application. Its standout feature is the integrated community, where learners can submit writing and speaking exercises for feedback from native speakers. While the core curriculum provides a solid foundation from beginner to intermediate levels, the quality and speed of community feedback can vary. The app's speech recognition tool is functional but not its main strength, making Busuu a strong choice for those who appreciate guided learning supplemented by human interaction.
