Campaign Management Tools
These digital tools strive to replace your physical notebooks and loose papers (seriously, go scan those before they get lost), making it easier than ever before to track every item, entity, and location in your world. You can spend months filling out your worlds, or just create a mind-map of names linked to each other with cryptic words that only you know the meaning of. That's part of being a Dungeon Master.
Campaign Journals & In-Session Tools
The Goblin's Notebook - new and shiny!
See all of your adventure components on one page, with easy relationship management, cross-linking, and full markdown support.
Link anything to anything else (with fully custom relationship definitions), and filter objects by connections. Also, connect objects to Chapters and show only that Chapter's objects on your screen.
Turn on Campaign Logging Mode and track changes to objects (and take notes!) in real time.
World Anvil - worldbuilding tool, industry giant.
