Does notion comes with Zotero integration ? I use Obsidian because it’s free + I can easily import a paper from my collections with a template which contains the paper’s name, authors etc. I like the community plugins too, makes everything pretty convenient.

I use Obsidian to note things with markdown + highlight things in the paper + eventually make slides about it

I think about writing blog posts about some methods on my web page to further my understanding of some techniques.
