Readwise
Readwise is a digital reading utility that aggregates highlights from platforms like Kindle, Instapaper, Apple Books, and more into a single, searchable library. It applies spaced repetition algorithms to resurface your best highlights daily via email and a dedicated app, actively combating the natural forgetting curve. Targeted at avid readers, knowledge workers, and lifelong learners, it includes tools for tagging, note-taking, and exporting highlights to note-taking apps like Notion and Obsidian. Core capabilities include automated highlight syncing, daily review curation, and integration with various reading apps and note-taking systems. A more advanced feature is "Chat With Highlights," allowing AI-powered exploration of your highlight library for new insights. It's a paid service with a free trial, designed to transform passive reading into an active, retained knowledge base.
