Readwise Reader

Best For:
Power readers, researchers, and anyone building a personal knowledge library.
Cost:
Free trial available. Subscription required for full access ($8.99/mo).
Readwise Reader is for people who don’t just read a lot, but also want to keep what they read in one place. It’s built like a Swiss Army knife so that articles, RSS posts, newsletters, PDFs, and saved highlights can all live in one place.
The reason power readers love it is that it makes handling your reading list incredibly easy. You can organize your files, export them, and actually build a personal knowledge library instead of losing ideas to the void.
It’s not the simplest app on this list, but that’s the point. If you want something basic, Instapaper is easier. If you want a reading command center, Readwise Reader is the kind of app you set up once and then wonder how you ever managed without it.
