I've used Obsidian for a couple years. It's a very good note-taking app. Vault (a paid add-on) makes syncing across devices effortless, but other cloud solutions also work. Composing in markdown's fast: your hands never leave the keyboard. It stores notes in markdown, so there's no lock-in: you can open them in a text editor. Once a note is synced to your device, you can reliably get to it even when you're offline. Quirks are in tables (a bit clunky) and the outline (hard to find on phones).

Just started using this for a worldbuilding project, and I'm a little addicted to the Wikipedia style linking and the filepath display. Sometimes getting links to work is a little frustrating, and I don't quite understand how to use aliases correctly, but I think those are mostly me problems (or mobile problems, cause this probably works so much better and cleaner on a computer). I do want a way to quickly find empty files, cause I've left a bunch of them lying around.

Rarely do i give any review, but Obsidian is well worth it. I've had a writing project floating around for over a decade and it is currently at over 800,000 words. I've tried various ways of sorting it, but obsidian is the only way I've found to make it work. Whatever you need likely has a community plugin, or if it doesn't, you could code it yourself in Markdown! It is extremely lightweight (we're often talking bytes) and with Obsidian Sync it works across all devices! highly recommended!
