Readwise Reviews

  1. Great help to review books

    I imported my kindle highlights, as many others. Now I daily review some highlights (thanks to a dashboard, I am motivated). And where I didn't create highlights, as I only listened to the audiobooks, I get the highlights from others. It also allows to create beautiful quotes. It adds the book cover and matches quote and background with colours found on the book title! Really nice!
