Not OP, I considered zotero, but for me, I used mobile too much and it seemed that it was a bit of the "wild west". I settled on Joplin which has a mobile app and has been great for me over the past 6 months. I'm working on a FF <-> Joplin bookmarks mirroring browser extension, which would get all of my bookmarks into Joplin as a SSOT.
Good point. I don't use it on mobile (I sync things between my personal and professional computer mostly) so I can't comment much on this aspect.
Joplin seems very nice indeed! But it seems to be more oriented for personal notes no? I mostly use Zotero for archiving webpages and various digital media (Zotero allows e.g. to embedded an epub as an item, or to add a link to a file stored locally).
Joplin has a bookmarklet that lets you screenshot or copy html if you want webpages: https://joplinapp.org/clipper/ I haven't gotten too deep into the "media" aspects -- but it's been great to act as a "digital note hub" that encompasses writing, research, and tagging.
Papership exists for iOS. It's not perfect, but it is good enough. I principally use it to search through the tree structure of documents, and then open them with other apps.
I'd like to agree and say joplin is great. I use synching to make sure my jolin notes are automatically synced between my phone, home computer, and work laptop
Joplin does not offer any original synchronization system. It just offers NextCloud, Dropbox, Onedrive, Webdav or the local filesystem. If you don't use any of those services, or you do not have a server where to setup Webdav, Local filesystem + Syncthing seems like the best choice.
