Learning this with a single page application is very handy, though I am curious, from where did you get these details about all the religions. I am sure you must have spent a lot of time on research.
Did you use any AI for this? You are claming you built everything from scratch which is impressive. But if you didn't use AI , I would how much it time you took to build this.
Also I saw your repo and it looks like you built it in a week so I doubt you did this without AI.
Regardless, please let us know what the X factor of this OS?
