I've been using it for about 3 years, and never paid for it. You only need to pay if you want the sync feature, which I don't use. And there are workarounds anyway that let you sync for free.

I also use Obsidian for worldbuilding and brainstorming for my novel! I think it's amazing.
It's a place for writing down EVERYTHING related to my book.
- Research on medieval history
- Notes on other fantasy books I have read
- Summaries of ancient literature and mythology
- Plot...
