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. :)

I really do like it. but whats extremely upsetting is that the format is really tedious to use. sometimes it wont let u add all of the characters u want in a story, even if u put their names in. & how the "save" system works tends to throw me off. I dont know if Im using it wrong? but I cant save unless I finish a chapter, & even then, sometimes it will still delete that chapter entirely anyways even if its said its saved. I truly do love the app, but its just incredibly frustrating & tedious😞

The bots' memories are terrible. I tried several different stories/ characters but had the same issue. The app uses the same 3 voices & the music stops periodically. Characters can't even pronounce their names, are very hot and cold, indecisive, or completely unable to adapt. You end up in circles trying to progress your storyline further only for the entire thing to restart. It's a good idea and needs tweaking, maybe different voices too. Thankfully it's free.
