Description

Description

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.

MosaLingua is built around a highly effective Spaced Repetition System (SRS) designed to help you learn and retain a large amount of vocabulary efficiently. The app prioritizes the most useful words and phrases to accelerate practical knowledge. While its core is flashcards, the platform also includes dialogues, articles, and other resources to add context. It is a powerful tool for learners dedicated to building a strong vocabulary foundation, though they will need to look elsewhere for structured grammar lessons or extensive conversation practice.
