What Readwise does best

Readwise automatically imports highlights from Kindle, Apple Books, articles, and PDFs, then resurfaces them via spaced repetition. The companion Reader app is a full read-later + highlighting powerhouse.

Who it's for: Remember everything you read. Sync highlights everywhere.
