Time for me to put something in this bag of holding:
Obsidian a note taking tool with a *LOT* of potential as a TRPG manager.
I was a very happy Realm Works user, but unfortunately that app has been pretty much abandoned by Wolf Lair.
Tried several other solutions in the mean time, but none came close of an offline solution with easy export options and/or the feature set of RW.
The great part about Obsidian is that the tool is free for personal use, supports plugins and as it happens severa plugin authors have been making plugins specifically catering to the needs of GM’s.
Obsidian work with MarkUp text, making it easy to format texts easily.
Plugins then add additional functionality like map and image support (with pins to link to articles!), better folder functionality, custom formatting and style , etc.
Josh Plunkett, a former RW fan, has created a nice playlist to show you what Obsidian can offer GM’s and what plugins you’ll need.
