I've had a good experience with using Scalar as a reference work - you can describe a place and link all the organizations, people, and smaller places within it, but then you can also look at your "people" tag(s) when looking for an interesting NPC, your "low-level" tags when looking for a challenge for a new party in the same world, etc. More useful the larger your world grows. The features that distinguish it from similar tools IMO:

1. When you hover over an internal link, a short description pulls up, so you can say "the tower has three guards" and when you hover over guards, you see their brief combat stats, provided you've set that as the description on the Guard page.
2. You can upload images and annotate specific areas of the pictures with whatever you want, including links. So you can have a dungeon map with little hover-reminders for you of what encounters take place in each room.
3. You can embed media, like YouTube videos, either at a specific spot on the page or so they follow you down the side. Useful for soundtrack switching.

It's not the best for quick editing in place, though, so I use a GDoc to keep track of changes, then go back and edit them in during a break or after a session.
