You finish a chapter, feel like you understood it, and a month later almost nothing is left. That is the normal outcome of reading, not a personal failing. Reading is passive: the text goes in, feels clear, and leaves no trace you can retrieve. Deepen makes it active, and it takes about a minute. HOW IT WORKS 1. Log the pages you read. Your progress bar moves. 2. Deepen asks you one open question. "What was the author actually arguing there?" or "What did you disagree with?" 3. You answer out loud, in your own words, for about a minute. 4. Your answer comes back as concepts, connections, and the questions you still have. 5. Those concepts join a map of everything you have ever read. Speaking an idea back in your own words is retrieval practice, which is the best-evidenced way to turn reading into memory. Almost nobody does it, because writing notes is work. Talking for a minute is not. THE MAP IS THE POINT Every concept you articulate becomes a node. When the same idea shows up in a second book, Deepen links them without being asked. Over a few months you stop having a pile of separate books and start having one connected body of reading. Read something about legitimacy in a history book, meet it again in a book about organizations, and the map shows you the two are talking to each other. ASK YOUR OWN LIBRARY Ask a question in plain language and get an answer built only from what you have said about the books you have actually read. Not the internet. Your own words, with the notes they came from listed underneath. NOTHING IS EVER SCORED Deepen does not test you chapter by chapter. Nobody wants to be graded on their evening. The questions after each session are open and never scored, because the point is to make you think, not to make you correct. When you finish a book, it asks once more: what will you still be thinking about in a year? Your answer joins the map like any other. It is a lap of honour, not an exam. ALSO IN THE APP - Keep the words you had to look up, with the book you met them in - Keep the passages worth remembering, and share one as a sticker - Scan a barcode to add a book, or import your Goodreads shelves - A home screen widget showing the book you are on WORKS WITH PAPER Deepen never asks what you are reading on. Paper, library copy, hardback, secondhand, an ebook, a PDF. You talk, so it does not matter. Nothing to sync, no highlights to export, no cable. BUILT TO BE PRIVATE Your notes and your map live on your iPhone. The map is computed on the device, so it works with no signal at all. There is no account and no sign-up. FOR PEOPLE WHO READ ON PURPOSE Deepen is for nonfiction readers who want the reading to stick: students, researchers, people working through a field, anyone who has ever finished a good book and been unable to say what it argued. DEEPEN PRO Deepen is free to try. Pro unlocks unlimited recaps, the map across every book, and Ask. - Monthly: $5.99 - Annual: $49.99 with a 7-day free trial Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period.

Verdict
The clearest difference is rating: Deepen at 5.0 against Bookmarks's 4.4. Deepen also leads on review sentiment (100% vs 67%). Bookmarks's advantage is ratings volume (8 vs 1). On price, update cadence, ads and in-app purchases there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Bookmarks sells 1 one-off in-app purchase and Deepen sells 3 in-app purchases, starting at $6.99 per 7 days. Whichever you choose, the download price is not the number that matters.
Deepen holds the better App Store score, 5.0 against 4.4. That said, the two scores are not equally well evidenced: Bookmarks has 8 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 67% of Bookmarks's written reviews are positive against 100% of Deepen's.
Bookmarks ships an update weekly, Deepen every 5 days. The most recent releases landed on October 24, 2026 and October 23, 2026 respectively.
