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.

Lingvist is a vocabulary-building tool that uses AI and spaced repetition to teach you the most statistically relevant words in your target language. It presents words in the context of full sentences, helping with comprehension. The platform continually adapts to your performance to optimize learning speed. While it is highly effective for rapidly expanding vocabulary, it offers minimal grammar instruction and no conversational practice, making it best used as a supplement to a more comprehensive program, especially for intermediate learners.
