### 1/5 — All AI based and no real control

*2026-07-02*

I was looking for an app where I could honestly write everything myself and create the world myself but this is ALL just ai. You can’t create your own world, it’s reliant on just ai generated prompted slop.

**Developer response:** Hello. The app is explicitly described as an AI-powered world building app :) There have been requests for manually inserting creations which we are working on! We hope you will give our next update another try. 

August 24th Update: We have added the capability to make any addition you want into a world :) The world (save file) still needs to be ai generated but you can add anything you want into it now!
