Whenever you’re venturing out to create your own world, be it for a DnD game, a book, or even just an art series, having your world fleshed out will always help strengthen your final product. Even if the details are aspects people will never see or read about (see all the lost tales book for Lord of the Rings for example), you knowing why the world has evolved a certain way, or where in it a certain character has traveled can really give your world a bit of realism and grounding; no matter how fantastical it is on the surface.
Making notes is a great way to get this process started and, I don’t know about you, but I have a tendency to lose journals/note pads or find them hard to navigate since it’s always being added to, but I can’t add to older sections if they’ve run out of room. To aid in this I’d like to present, notebook.ai.
Not only does this site help you keep all your notes in one place, it goes much much deeper then a simple notepad function. This site will ask you questions about your world and save your answers. It will check to make sure you’ve made no continuity errors. If you’re working on a group project you can invite others to join and keep all your work in the same place. This site will let you go as deep as you want with your world building and keep it all nice and together for as long as you need. Oh, and did I mention it’s completely free?
There are paid tiers if you’re really into world building (ranging from $9-7 a month) but for the casual user the free subscription will be more then enough. I wish a site like this had existed 10 years ago when I dabbled in writing, lol, but if creating worlds is your thing then I highly recommend giving this site a try. The ease of access and customizing is so worth it.
