Plug for something like Obsidian here. I recently started a new novel and the ability to divide everything into folders and sections that I can link to within my writing has been invaluable.

If it’s been a while since I referenced a place or event or character, I can write their name and link out to their dedicated page full of info and reference material on them. If I have something I think of on the fly that I want to remember, I can create a new reference page and link to it, or add it to an existing page whenever I need to .

The organization is a game changer. I write chapter by chapter, sometimes bouncing around in the timeline, and stitch everything together as I finalize a section.
