I used to use this offline bLADE wiki software, which I think now has vanished from the internets forever. A shame! It let you make very simple offline web-pages where you can store images and text without any HTML knowledge. Now I just use good old MS Word, with a careful file name organisation by general topic. Oh yeah, and keep a backup copy on a USB... just not too sure about this Google Drive thing.
I have a lot of sketches and pictures (mainly maps and clothing references) taped to the wall behind my desk, and a bunch of Word documents with character info, world history, the language, etc saved on my laptop.
I did actually make a website (more for my readers' reference if they want it) Burning Bright Info Site1. Most of the stuff I have saved is a lot of backstory and random details and facts that won't make it into the actual comic but help with world and character building.
ok so im the most organized unorganized person when it comes to this shiiish.
I have word documents. thats it, just word documents and each story has its own word document, the names are usually INCREDIBLY basic. For my one story with my redhead, its just simply "Notes" and that has EVERYTHING from the time line to chapter lay outs to ages, names, eye colors- EVERYTHING. However its the most unorganized thing ever. Everythings just... there. Since i look through it SO much I know whats in it and where to look. But if i gave it to anyone else to decipher no one would have any idea how I manage. @w@
My comic morgan and dragons1 has the same thing. A single word document that has EVERYTHING. the quests that we did and if we completed them, our item list, and EVERYTHING i've copied from each dnd session.
Grogthor and Jennet might be my least complex however. There document just contains a script, as its a story about online gaming i feel it better for the lore to be one of those things not talked about, you see mobs and hear characters talk about different zones but ive never mapped it out or given mobs names. Not sure if its lazyness or if i enjoy the fact readers (and myself i suppose) just don't know and my never know what some things are.
if the story is short & easy, i write all on a file in notepad.
if the story start to be "big" , i create 1 folder with many notepad files: 1 fo the charas + 1 for the story (for me, so with all the spoilers) + 1 for the REAL story (the one that ll be the comics + 1 for the notes (like: put that spaceship somewhere or talk about x or y)
if the story it s "heavy" i use html programs, where everything s linked. so there re pages for the story, for the charas, images, reference and so on. like a big wikipedia...
For my comic, I have a separate A5 sketchbook for the storyboards as well as some sketches and notes of the characters but nothing too much. However I tend to change the stuff in my storyboard so much to the point where it became so messy I had to create a word document with like a summary of what goes into each page (I work in webtoon strips so a lot of stuff happen in a page) and that helped me organize my ideas. I also started writing out in details future scenes so that I don't forget them.
For my comic I have everything stored in one folder. It used to be very unorganized but I took the time to create folders for the various aspects of my comic. (pages, scans, scripts, banners, drawings, etc) I has been a huge lifesaver. Now anything I create something pertaining to my comic I have somewhere to put it without clutter or confusing myself.
Scripts, scans, finished pages etc. are stored on my pc hard drive and also on an external hard drive.
Layouts, character designs, original panels etc. are in a -more or less- well organized portfolio.
I need to write down everything, I'll never could keep all in mind. I have a very short memory, like an old grey lady.
I've got 3 separate 150pg sketchbooks, a full 3-ring binder, and a folder with 1gb of picture files/text docs on my computer desktop. The content that has been put on paper is shamefully sparse compared to the 10 years of development I've gone through for the story in my head. Not to mention that a lot of things change as I learn more about art style, people, culture, and the world. The story I have today is really nothing like the story I had 10 years ago. I'd love to pull it all together into one big well-organized repository that I can manage. I can usually remember most of what I need while working, but it'd be nice to have for my readers if I somehow end up with a fan-base.
I keep a grimoire of stuff concentrated in a Word doc. That's where most of my info goes. Then, I have a single text file where I write down various small ideas, which is generally snippets of dialogue, a chapter idea or a scene.
My Word doc is my baby though. I keep it neatly organized as I can (well with lots of TODO notes) so the navigation sidebar looks nice... （´＿｀）And so my writer can actually find shit! It pretty much has all info about the world in it.
My actual concept art though is all over the place. It sits in my general art folder with the 5000 pieces I've done. Not good with that. I've recently started to organize my character design folders so I'm getting there.
Sketchbooks, notebooks, word documents (and everything digital is on dropbox as well as external hard disks).
I think it's smart for creators to make sure to write things down and have all that kind of information stored elsewhere than just your own head. If you should be very unfortunate and end up in an accident of some sort that would do serious damage to your head, you could be at risk of losing that information. You would probably have bigger worries if something like that happened of course, but it's nice to know that at the very least I have a copy of all comic-related information safely stored outside my brain, so I don't risk losing it forever if something should happen. Not that you should walk around and constantly worry about hitting your head though 
I am curently in the making of a book that contains all the information on the world of Stormspectrum, divided in races, countries, laws, foliage etc. Along with that there are pictures to explain everything. It has a index and all, so if I need something but can't remember it from the top of my head, I search in The World of Stormspectrum. Wich I constantly add stuff to.
It's all in my head. Have tried writing the world info out as a supplement for my players for Pathfinder. It's far more organized in my head.
I record ideas i need to keep in mind, but I'm not neat or tidy about it in any way xD I literally have a libre office filed called "time gate shit" that just has a list of things I don't want myself to forget to do as I progress the story (just important events and interactions that I may or may not forget about). When I'm not in "time gate shit", I just track quick thoughts and ideas in Notepad, then move them to the libre office file where I save the ideas if they're good enough xD
I chew it up then spit it out all over the page. Funny you ask. I'm working on a huge idea right now. So huge that I filled an 80 page notebook with lore.
I use google sites to organize my lore. (Partially because I needed to be able to share it with others and didn't know of any other free ways to do it that easily, buuut.....)
