About Readwise
Readwise solves a universal problem: you read great books and articles, highlight important passages, and then never see those highlights again. It aggregates highlights from every reading source and uses spaced repetition to resurface them daily.
Readwise Full ($8.99/month) includes highlight sync and daily review. Reader (included with Full, or $8.99/month standalone) is a read-it-later app for articles, PDFs, newsletters, YouTube, and Twitter threads. Combined: $13.99/month for both.
Highlight sources include: Kindle, Apple Books, Google Play Books, physical books (via OCR), web articles (via browser extension), PDFs, podcasts (via Snipd), and YouTube transcripts. Everything flows into one searchable library.
Daily review emails present 5-15 past highlights with spaced repetition timing. Research shows this dramatically improves retention — you actually remember what you read months later. Reviews take 2-3 minutes and become a beloved daily ritual.
Reader deserves special mention: it's a gorgeous read-it-later app that handles articles, newsletters, RSS feeds, PDFs, EPUBs, and YouTube transcripts. Highlights made in Reader automatically sync to Readwise. It's replaced Pocket/Instapaper for most users who try it.
For knowledge-focused solo founders, Readwise is the connective tissue between reading and thinking. Highlights flow from books to Readwise to Obsidian/Notion, building a searchable knowledge base over time.
Limitations: the combined subscription adds up ($13.99/month), casual readers won't see enough value, the system requires building a daily review habit, and some highlight sync sources (physical books, certain apps) have friction.
