Readwise Reader is the only tool on this site that directly attacks forgetting: it stores what you highlighted and pushes it back at you later, on a schedule, without you remembering to look.
What it does
Articles, PDFs, EPUBs, newsletters, RSS feeds, and YouTube transcripts land in one inbox. You read them in a clean, adjustable surface, or listen to any of them with built-in text-to-speech. Highlights sync into the Readwise system, which mails or shows you a small selection of your old highlights on a spaced schedule, and exports cleanly into note apps if you keep one.
Where it earns its score
Retention support, by a wide margin — this is the highest score any tool has taken in that criterion here. For a reader who finishes a great chapter and has lost it by Thursday, resurfacing is not a bonus feature, it is the entire reason to use software at all. Format fit is the second strength: sending a PDF, a newsletter, and a saved article to the same queue removes a startling amount of daily friction. Text-to-speech on everything means the queue can be cleared while walking.
Where it loses points
Start friction. Reader is dense — multiple views, keyboard shortcuts, filters, and a genuine learning curve before it feels calm. The price is a real subscription rather than a token one, and the app can enable a specific failure mode in this audience: a beautifully organised backlog that functions as a hoard. Cap the queue deliberately, because the app will happily hold a thousand things.
Who should use it
People who read to use what they read — students, researchers, writers, anyone whose complaint is "I know I read something about this". Also anyone drowning in newsletters.
Who should not
Readers who mainly want a peaceful place to read one article at a time should try Matter, which does less on purpose and is calmer for it. Reader vs Matter →
