Interesting concept. Make characters play with each other rather than yourself. The stories it generates are short, and memory between stories isn't great. Sometimes, when you edit a message, it regenerates from the end of the current generation instead of from your edit. In addition, sometimes it'll make a message longer than it allows you to edit.

I've been using this app for a few months now. I think it is very innovative and brings a unique way to create your own fanfiction.. A few issues that absolutely needs to be addressed. Roleplaying a character and then posting doesn't allow you to just listen and watch it pauses at the roleplaying parts. When you change dialogue it frequently fails or ignores what you want in the story. Lastly,it cannot remember the story leaving for heavy editing but with the AI preventing edits due to the fails

overall quite well, very well done, quite the experience, although sometimes it instantly puts the recommended choice in the chat when you choose to place your own response and your own response gets placed in front of the automated sentence, and this makes it almost usable, unless I wanna see the story, otherwise it is hard to find certain directive (fixed (I think), and I corrected the review to not accidentally drive people off.
