This app is great the only issue is you can't turn off the narrator and you can only speak during specific parts of RP which always has the same beginning. The voice AI mixing thing doesn't work very well unless the character is speaking very clearly causing accents to be harder for it to do. It is annoying that you can't edit your already published roleplays especially if you made a mistake.

Currently works well. It's amazing for creating custom stories with your favorite anime characters or even your own custom characters. Although it is annoying because sometimes if your story takes a more NSFW turn it will work perfectly sometimes with no issue, but more often than not, it'll never load the dialogue as if there is a server issue. sometimes even if there is no NSFW intent and it's just implied.

Sorry about that! The server was experiencing some issues earlier but should be stable now — please try again to see if it works. For other bugs like failed message sending or voice issues, we're still working on a fix. Thanks for hanging in there!

Seems pretty fun so far! My main problem right now is trying to continue the first story. It wouldn't be so bad If I could post what I've edited so far and then add to it after- That seems like an easy feature but I don't see a way to edit stories after submitting it. I keep trying to edit the story but an error (failed to Regenerate) happens or I leave and the continued story is gone. A simple fix is to make submitted stories editable. UPDATE: they added a draft feature which is a nice comp. :)
