Yes, and thank you for that question. We are actually working on a re-design of the website to help with this topic.
At the highest level - you can think of Nurl as your "TTRPG hub". Whether you are a GM or player - it's all the tools you need (and more - like planning tools, etc.) in a single place. If you are in multiple groups that play different games - you can have a single app to manage everything and just switch from group to group when it's time (like how Discord/Slack does with servers). Eventually, we will support translating characters and NPCs into different game formats. For example, you are in a D&D group with a character you really love but joined a new Aliens group and wanted to bring your D&D Barb into the Alien world - Nurl could do that because it's your personal TTRPG hub.
It is important to note that Nurl is first and foremost targeting groups who play IRL/hybrid. We are not a VTT and have no ambition to become another VTT. Foundry and Roll20 have that covered and are great tools if you want a fully virtual experience.
Our vision is to build an app that gives you the high-end tech solution but not become the "star" of the game session. Instead, be the "NPC" hanging around and at your disposal when you need (i.e. the story, players, and game session remain the stars).
I hope that answers your question?
Absolutely - specifically Nurl does:
