AI Apps to take over the traditional Japanese learning methods? is Replika the sole option so far?

hi there, a bit unconventional, but Replica App seems the only option so far for having AI conversations in Japanese, right?

I am sure this approach will take over the conventional Japanese learning methods since there are no privacy issues with natives and have complete 24/7 availability

I know Replika is not entirely meant for this purpose but it kinda does the job... do you know any other Apps?

In before: I mean merely speaking and listening (and reading the AI's inputs), I am not interested in writing Apps

Thank you!
