Technology

It uses a mix, it does not hallucinate words and it's actually pretty good at catching stuff like grammar mistakes. I find the big value is that it forces you to do free form conversation where you have to think on your feet. I find this is more valuable than just reading and memorizing stuff which other apps do. I ended up getting the Plus plan, and definitely feel it's been worth it. The app itself also has a lot of regular lessons, the AI isn't the only part of it.
