Are you tired of having to look up words while reading online articles in the foreign language you are learning? So are we! Vocabular.io solves this problem by extracting words from the article you want to read, and then helps you learn the words that are unknown to you before you start to read the article itself. This way your reading flows more easily, and you avoid interruptions caused by looking up words while reading. Also, you are exposed to the new words twice, since you are actually repeating the word you learned before starting to read the article.
