Collects your reading highlights and resurfaces them for review
Readwise gathers highlights and annotations from ebooks, articles, podcasts, PDFs and paper pages into one searchable library, then sends a daily email or app reminder with a selection to review. Reader, its read-it-later app, adds a reading queue with annotation tools and an AI assistant called Ghostreader, which can summarise a document, define a term or answer questions about a highlighted passage. The spaced review loop is the point: highlights that would otherwise stay buried in a Kindle or a folder return until they stick. It is a paid subscription for individuals, with a student discount.
