Reviews

Lexi is an excellent language learning extension for saving all the words I come across online in one place. It works perfectly as a word translation tool and vocabulary trainer, allowing me to instantly understand and collect useful words. If you’re looking for a vocabulary flashcards app that fits naturally into your daily routine, this is it. I also like that I can practice whenever it’s convenient. The design is another big plus — the visuals are engaging and beautiful. I would rate the whole experience 10/10!

Lexi learning tool has boosted my progress with the languages (both English and Spanish)! The browser extnesion is a really helpful suplement to my learnign routine. So often I am puzzled by a word in an article or news, which I have already seen, and in the end I just don't bother finding out the translation and meaning of the word. With lexi I have all these tricky words in flashcards and I finally learnt them.
