title_body: calibre - how to upload my highlights online? I'm using calibre to upload books to my kindle (via usb). So my amazon account is not aware of my books.
  
  I want to be able to view my highlights and comments online somehow. 
  Since my books are not connected to my amazon account, they do not appear in the link https://read.amazon.com/notebook. 
  
  Is there any way to upload the notes and highlights automatically to some online service? 
  
  Or even not automatically? I've tried the Fetch Annotations in calibre, but it didn't work.
upvoted_answer: I found this site: https://my.clippings.io
  
  It allows you to upload a file named my clippings which is downloadable through the fetch annotations button in calibre. I found this file in my library after performing the fetch.
