Possible Story Plotting Aid

I stumbled across a website advertised on a youtube channel, so take it with a grain of salt, called World Anvil that may be a useful world building tool supposedly good for plotting rpg fantasy/sci-fi and in my opinion possibly other types of stories.

Disclaimer: I have not used this and I am not sure how the site monetizes the use of anything you create on the site, maybe there are non-web type software similar to this for story development but it seemed interesting that such tools are available.

The web site is www.worldanvil.com
