I appreciate Goodreads for its pretty extensive catalogue of books, the ability to see reviews from other readers, and the social aspect of following what my friends are reading. However, I find both the website and the app very slow and not very well designed. Plus, I liked to minimize my interactions with Amazon. Has anyone used or built any alternatives? While the features I listed above are nice, the only ones I would really want are:

• The ability to quickly look up and add a book to my "want to read", and to keep track of books I have read
• The ability to leave notes or reviews on books (not necessarily visible to others).

I've started to keep a reading log in Notion which satisfies the second point above, but there's no easy way to search through a data base of books and add a book to one of my lists. It would be nice to be able to do so on the fly as I browse books at the store. So Tildeños, what solutions have you all come up with to track your reading?
