No, it was specifically aimed at worldbuilders. Thanks though

I'm afraid not, I believe it was in development by someone in the subreddit.

Thanks anyway

Scrivener? There’s an iOS and Mac app. It’s designed for world building.

It was like OneNote with extra bells and whistles, you could draw boxes around things to group them and create relationships.

The example given was a large box as a continent, surrounding smaller city boxes which in turn contained details of people in those cities.

If someone could find it for me again I'd be very grateful.

Looking for a tool I saw here a while ago
