I use the superior method, a mess of illegible scribblings in a journal. I am trying to get better about it, though. And one thing im really trying to do is focus my prep on what the region is like, and what the important actors there are doing, and not on what i think the players will do. Every time I try to predict the pc actions they completely flip my prep on its head, so I want to go for more of an "informed improv" type prep

I use Onenote, it's free. Let's you have a book with folders and pages. You can have blank lines dotted or graph paper. You can use it to search images uploaded to it. Combined with a surface pro to write on the screen I can do everything I want to from draw maps, edit character sheets and take notes. You can hyperlink between pages and print pdf's into it. Fabulous piece of software for RPGs.

Poorly! I do it poorly! :D

Characters are in GURPS Character Sheet, an (awesome!) open source character management program. I run our games through Foundry VTT, which handles all the combat tracking, HP/FP management, maps when I have them, etc. It also imports GCS files (and GCA, if that's your flavor of character editor). Most of my other notes (events, generated people names for unexpected NPCs, etc) go in Google Keep notes. Notes that I have to take on the fly go into my notebook, where they go forgotten until the next session, more often than I'd like...

For notes during/right after a session I have a notebook where I write by hand.

For planning, loose ideas etc I used to use Trello. It was serving me well for a long time (I'm still using it to save maps I might want to buy, interesting systems, links to tools, etc) but with time I felt I'm lacking a kind of big picture view.

So for campaign and adventure planning I've switched to obsidian.

• I like markdown
• With plugins you can create random generators
• I like that it's simple. It's just a bunch of files which I sync to my cloud
• The graph view lets me take a look at arches as a whole and find loose ends/underutilized facts

Between sessions: Google Docs (one document per campaign)

During the session: I'll print out the document and scribble on it with a pen as needed. I've tried editing the doc live (via laptop) during the game but it takes too long and requires too much focus to type as opposed to just jotting down/crossing out as we play.

Paper in a folder with index sheets. Old school as hell.

I tried Obsidian recently for a homebrew game and it worked really well to however.

I use cherrytree. It has hierarchical note taking, hyperlinks and anchors. I make separate nodes for separate note categories. It works well for me, keeps stuff mostly organized.

I use obsidian, and git to sync between devices.

Three pieces of paper: Apocalypse World's the threat map and two threat sheets.

The game is so flexible that I don't need to plan much.

If I forget something, players will surely remind me, and that's okay. We're there to play a fun and interesting interesting game in which we can improvise and course-correct. We can all pitch ways in which to integrate the forgotten-and-later-remembered fact to our current game. In that way, it's a much more collaborative and free game.

We are not playing a game in which I am playing against my friends and so we all have to keep track of everything, just in case we need to rule-lawyer each other.

Neither are we there to play a game in which the lore is completely separated from the actions that the players take.

In Apocalypse World (at least the way my friends and I play it), the lore is created as we play, based on the actions that players take. This means that nobody is sitting for hours coming up ideas. Rather, we are playing a game and seeing the world 'render' before our eyes with every decision the players take. Sure, I also take decisions, but the vast majority of them are taken in real time, before my players' eyes. We're all there to see what happens, because nobody (not even I, the GM) knows what will happen!

Oh, and if we all forget something, it doesn't matter; we're all still gonna have a blast!

MS OneNote is my preferred tool for this as you habe an infinite notebook and can doodle anywhere on its infinite pages. I usually have a chapter for rules, NPCs, Fluff (locations and past events), PCs (their history and plot hooks), with pages for e.g. combat rules, 1 page per NPCharacter etc. You can import pictures (and also paste them directly from ON to Discord) and share the notebook (or single pages) with others online.

I used to keep text files on my computer, I got into a rabbit hole creating a bot to roll dice, store characters and also notes, and eventually I found Notion, I started to use it and so far it's been great, I haven't kept too many notes, but I'm organizing a Monster of the Week world and it's been great for creating monsters and planning sessions that link with the monsters so I have all of the info available easily.

Gm notes? what are those?

seriously though, I have someone in the party keep a journal of things that have happened. Then I keep a bullet point notes in a notepad or piece of paper that I have behind the GM screen.

I use WorldAnvil for all my GM stuff :D Got my notes in their notebook, my worldbuilding in articles, etc etc. It's a bit of a heavy program unless you're going hard on worldbuilding, but I do go hard on worldbuilding so it's perfect for me.

Used to use onenote before, but those aren't really searchable last I checked.

I'm a big fan of the Notion template from Sly Flourish. You can find it here: https://slyflourish.com/lazy_dnd_with_notion.html

Obsidian is a personal favorite.
