LingQ is a language learning platform built on the principle of comprehensible input. It provides a vast library of articles, podcasts, interviews, and books, often with accompanying audio. As users read and listen, they can instantly look up new words and save them as "LingQs" for later review with a built-in spaced repetition system. The app visually tracks vocabulary growth, allowing learners to choose content suited to their level. It's an excellent tool for intermediate to advanced learners looking to expand their vocabulary and improve comprehension through massive exposure to authentic material.

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.
