Its a great app, but i think it can be improved. 1. Fix some of the free chat AI options to where they work with stories that are long, cause some of them don't work well with long stories. 2. Allow us to create a mask for each story we do (who we are, our age, hobbies, things like that) it would allow for more freedom with each story, Cycle.Ai does this and works pretty well. 3. It would be great if the daily login crystals can go higher than 2 when you keep the streak alive.

Login with Google doesn't always work, which is lost progress. It does take a bit to load . It was nice while I played it. I did notice that, if I ask a specific character something, everyone jumps in, rather than 1-on-1 sidebars. So, pretend you're in a D&D session. Also, don't ad limit. You get ad revenue that way, right? I would like to do more free stuff to get gems as I use this app and all phone apps infrequently. My spectrum router blocks this so I play it in mobile internet at times.

overall a good experience aside from some small hiccups regarding the capabilities of the AI, like weird memory and terrible math, but that's not their fault. I've tried all sorts of other apps and programs like this and most of them are worse, this one has been the most intuitive and high-quality one that I've used so far. there is another AI story service set-up called infinite worlds but that's the only other one I'd recommend, more difficult to work with and more expensive though.
