Vocabulary is an essential part of learning a new language. Until now, you could use vocabulary cards or dedicated apps to do so. That works. But it requires a lot of dedication and planning. With Lexios, we allow our users to learn vocabulary effortlessly while browsing the web. Scientific research clearly shows the advantages of this approach. That's what we base our product on. What is Lexios and how does it work: A user installs the browser extension on this notebook or desktop (at this stage, we don't support mobile devices). We offer extensions for Google Chrome and Microsoft Edge. After installing the free extension, the user chooses the target language and the base language. Then, the user chooses the current level of experience (A1 to C1), and the learning journey starts. While browsing a website (e.g., newspaper) in the base language, Lexios translates relevant words into the target language. We choose the words based on the context, the level of experience of the user, and an ideal spaced repetition. You choose the number of translations per page, and you can also blacklist pages that you don't want to see words.
