We can take you across Spain or Latin America with our AI tutors. We teach you how to speak either Mexican Spanish or Castilian Spanish from Spain. Don’t worry if you have never spoken Spanish before as our tutors will start from the very beginning. Already know a little? Then we also have conversations for you that will help you improve your language skills to new heights.

We help you learn over 2,000 kanji, covering N5 to N1, so you can reach your learning goals, whether that’s studying towards the Japanese Language Proficiency Test or just learning to read the web.

Helping me pick back up japanese

I have found this app extremely useful as it was able to immediately gauge my level of Japanese and put me into an appropriate AI class. Unlike other language learning systems I found this one to go at a quick pace which I prefer

J'aime et je joue ,

It actually helps!

I’ve only really had this app for minutes yet still if effects the urge to stay on all day or night to just be able to advance my ladle further because this app really makes it feel possible and realistic to be able to learn Japanese’s! It provides me with so much easy access simplified techniques and aids as to how to pronounce and write without making me feel like I have not earned the knowledge I gained by giving me help but not the answers, so I feel like every word pronounce properly has been completely earned by me and not simply just given. This app pushes you further every step of the way and it feels so encouraging and has just made my evening with one simple session!I highly recommend.

Could be better

So what’s actually here (in terms of content) in the app seems fine, no real issues there. My problem is with the app itself. In the chat function with the AI, as far as I can tell it’s impossible to scroll up and see the rest of the conversation beforehand and (more crucially) the flash cards if there’s long instructions, and when you start typing, you can’t scroll along what you’ve written to reread/edit it. These scrolling issues are in various places throughout the app (even when I very first loaded it and wanted to sign in using my google account, had genuine difficulty because the button was below the screen) and it’s honestly poor. For something so obviously designed to work on mobiles, it really should be better suited for them. Please fix this.

Developer Response ,

Hi Ongaku17, thanks for your feedback. It would be great to speak to you in more detail so we can get to the bottom of these issues as soon as possible. Please can you reach out to us at hello@kaizenlanguages.com with screenshots and more details so we can investigate?
