I've been impressed by the way Langua has continued to evolve and develop. The AI is increasingly sophisticated, for example it can randomly generate questions to allow me to revise tenses in an interesting way. There is immediate and helpful feedback. I've also been taking lessons with an excellent French tutor who has significantly boosted my speaking confidence. The website is easy to use, and the company is forward-thinking, innovative, and responsive, with the co-founders addressing my Qs personally.
