Readwise Reader

Readwise Reader is a read-later and reading management app that unifies articles, newsletters, PDFs, ebooks, and YouTube videos into a single inbox, then uses AI to help you process and retain what you read. The defining feature is the Readwise highlight review system: every highlight you make resurfaces on a daily spaced-repetition schedule so you actually remember what you read. At $7.99/month, it is the best-value tool for serious readers who want to extract lasting knowledge from their reading.

What It Does

Reader functions as a read-later app (like Pocket or Instapaper) plus an AI research assistant plus a long-term memory system for your reading:

Ingestion: Save articles via browser extension, subscribe newsletters directly to a Reader inbox, import PDFs, sync Kindle highlights, add YouTube videos for AI-generated transcripts.

Reading experience: Clean distraction-free reader with adjustable typography, offline access, text-to-speech for listening while commuting, and inline highlighting with tagging.

AI features:

• Ghostreader: ask questions about any document in Reader (“what is the author’s main argument?”, “give me 5 key takeaways”)
• Document summarization: one-click AI summary of any saved article or PDF
• AI tagging: automatically suggests tags based on document content
• Highlight extraction: AI identifies the most important sentences in a document if you are time-pressed

Spaced repetition: Highlights automatically queue into a daily review. Readwise’s algorithm surfaces highlights at scientifically optimal intervals to move them into long-term memory — the same principle used by Anki flashcard learners.

Export: Highlights and notes sync to Notion, Obsidian, Roam Research, Logseq, and Evernote. Every highlight becomes a potential note in your knowledge management system.

Who It’s For

• Heavy readers processing 10+ articles, newsletters, or papers per week who need an organized inbox
• Researchers and students who highlight academic PDFs and need those highlights accessible later
• Knowledge workers building a personal knowledge base in Obsidian, Notion, or Roam
• Podcast and YouTube consumers who want searchable AI-generated transcripts
• Anyone who finishes books without remembering them — the spaced repetition system directly addresses this

Not a fit for: casual readers, anyone wanting a simple read-later app without the complexity, or teams (Reader is a solo tool).

Pricing

Prices verified 2026-04-14. Annual billing available at ~$6.66/month. No free tier after trial — subscription required.

The pricing model is notable: $7.99/month covers both the Reader read-later app and the Readwise highlight review system. There is no stripped-down free plan after the trial ends.

Key Features

• Unified reading inbox: articles, newsletters, PDFs, ebooks, and YouTube all in one place
• Text-to-speech: listen to any saved content at variable speed; good for commutes
• Ghostreader AI: ask questions about any document using GPT-4 under the hood
• Spaced repetition review: daily highlight review queue with quiz and cloze deletion modes
• Highlight sync: exports to Obsidian, Notion, Roam, Logseq, Readwise API
• Offline reading: full offline support on iOS and Android
• RSS reader built in: replace Feedly or Inoreader; subscribe to any feed directly in Reader
• Newsletter inbox: subscribe newsletters directly to a @readwise.io email address

Limitations

• No free tier after trial — $7.99/month is required; the 60-day trial is generous but the pricing cliff is a hard stop for budget users
• AI features use credits — Ghostreader queries consume credits; heavy AI users hit limits on the standard plan
• No team or collaboration features — fully individual; no shared workspaces or reading groups
• Kindle sync requires workarounds — Kindle highlights sync via the Kindle API but requires periodic manual re-authentication
• Mobile app polish lags desktop — the web/desktop experience is superior; mobile is functional but not as refined
• No native book purchasing — you must get ebooks from elsewhere and import them; Reader is not a bookstore

Bottom Line

Readwise Reader is the best tool available for serious readers who want to actually retain what they consume. The value proposition is clear: $7.99/month for a read-later app, AI research assistant, highlight export, and memory system is exceptional. The AI summarization and Ghostreader features are genuinely useful, not tacked-on. The spaced repetition system is the most underrated feature in the PKM tool space — most people highlight things and never see them again; Readwise solves this. The no-free-tier policy is the only real friction point.

FAQ

Is Readwise Reader free? Readwise offers a 60-day full-featured free trial, after which a subscription of $7.99/month is required. There is no ongoing free tier. The trial is long enough to evaluate the product thoroughly.

What is the difference between Readwise and Readwise Reader? Readwise (the original product) is the spaced repetition highlight review system — it resurfaces your highlights from Kindle, articles, and other sources on a daily review schedule. Readwise Reader is the full reading app that includes the original Readwise system plus a read-later inbox, AI features, and newsletter support. The $7.99/month plan includes both.

Does Readwise work with Obsidian? Yes. Readwise has a first-party Obsidian plugin that syncs all highlights and notes directly into your vault as Markdown files. New highlights appear in Obsidian automatically. This makes Readwise the standard bridge between reading and Obsidian-based PKM systems.
