I would like to have an home library which i can access from all my devices.
Synching notes, bookmarks and highlits, it has to be accessible from android as well, i tried with nextcloud but doesn’t work very well.
Is Calibre good for that? How can i access those books and datas from my phone?
Memos, Benotes and BookStack come to mind. Note taking and Bookmarks and link sharing by the wonderful people at awesome-selfhosted might help you find exactly what you need.
