As for my notes, I use a big 9" by 12" spiral bound drawing booklet to scribble all types of notes during play. I eventually go and organize them into something more legible. I recently found Kanka.io which is a wiki designed for RPG's and I'm building out all the characters and notes into that for a database for me and the runners. - Source: Reddit / about 1 month ago
Kanka: a (free) wiki-like website for your game/creation, you can see some exemple here. Before that I was using DMmaps + OneNote but with Kanka it's much easier and smoother. - Source: Reddit / about 1 month ago
Https://worldanvil.com is another tool that can be useful. I find it a little daunting however. - Source: Reddit / 2 months ago
I'm currently using Roll20.com as a virtual table top (VTT) for my Pathfinder RPG and mostly like it, but since I know not to get too invested in any one tool, so I like to investigate other options. I'm using WorldAnvil as my knowledge repository for my campaign and the developers notes show it integrates with Foundry VTT. Yay, bonus! - Source: Reddit / about 2 months ago
