Has anyone tried "Hi.AI Chat"?

I found this app "Hi.AI Chat" on Google Play last week. Since the app's theme color is pink whic is my favorite color, I gave it a try. After using it, I realized it doesn't have overly strict NSFW censorship and I really like it. So I bought the subscription for 1 month to test the water. Anyway, I'm a new user and there are some functions that I'm not familiar with. So I'd like to ask whether there are "Hi.AI Chat" users here or not? And are there specific subreddit for this app?

Thank you.
