I use a site called LitLift to help me organize everything for my stories.
It's really great and it allows you to create detailed character pages, story scenes, and more. The character pages are the best part to me because they go really in-depth and you can even have a generator make up certain traits, quirks, or mannerisms for a character if you're drawing a blank (although some of them area bit wacky, but it's still extremely useful).
So what I've been using lately is This It has tons of tools on there to help you. A bunch of writing prompts and other things you need. One of my favorite sites to use!

Definitely check it out and hope I helped!!
