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.

Speechling is a non-profit platform singularly focused on improving spoken fluency and pronunciation. The method is simple yet effective: you listen to a sentence from a native speaker, record yourself saying it, and submit your recording for feedback from a human coach. This targeted approach provides personalized corrections that automated speech recognition cannot offer. It is not a comprehensive course for learning a language from scratch, but rather an invaluable tool for learners who have a basic foundation and want to refine their accent and conversational confidence.
