Ferramenta Meu Vocabulário

Hello guys, how are you? I hope you are well. So, I created this topic to talk about the vocabulary tool and I'd like to know how do you guys use this during the days, because when I add a new vocabulary I always get a little uncomfortable, thinking if the sentence is correct or not, because as it's a new word, it's easy to commit a mistake creating a new sentence. So, do you have any tip for me?
