What are Readwise and Study Junkie each for?
Readwise describes itself as a tool “to help you retain and organize the most valuable insights from your reading.” In practice it collects the highlights you make on Kindle, Apple Books, Kobo, Pocket and other sources, then brings them back in a Daily Review. Its companion app, Reader, is where you read EPUBs, PDFs, articles, newsletters and feeds, and listen to them with text-to-speech.
Study Junkie starts somewhere else. You upload one book or document (PDF, EPUB, DOCX and several other formats, up to 100 MB) and it becomes a course of chapters built from the full text, without summarizing or shortening anything. Each chapter can have AI narration, a tutor chat grounded in that book, problems set from the chapter, and scheduled recall questions if you switch them on.
So the real difference is the raw material. Readwise works on what you chose to save. Study Junkie works on the whole book. If you didn’t highlight a passage, Readwise has no way to bring it back.
A note on scope: plenty of people look for a Readwise replacement because they want a read-it-later app or an RSS reader. Study Junkie is neither, so this page only covers remembering and learning from books.
When is Readwise the better choice?
Your highlights already live there. If you’ve read on a Kindle for years, Readwise syncs those highlights automatically. Study Junkie doesn’t import highlights at all.
It covers your whole reading life. Daily Review draws from every book and article you’ve highlighted. Study Junkie is one course per upload, which suits deep work on a single book and does nothing for the rest of your reading.
It’s a full reading app. Reader handles EPUBs, PDFs and web content, and its text-to-speech reads the original text with adjustable speed, across iOS, Android, web, Mac, Windows and an e-ink mode. Study Junkie runs in the browser, which works on phones and tablets, but there is no native app.
Choosing what to highlight is itself learning. Deciding what matters is active work, and Readwise respects that.
It’s cheap if resurfacing is all you need. Readwise Lite is $5.59 a month billed annually, after a 30-day free trial.
When is Study Junkie the better Readwise alternative?
When the goal is to understand a book well enough to use it, not to see a handful of its sentences again.
Highlights capture sentences. They rarely capture an argument, especially in dense non-fiction or a textbook, where the point is spread across pages you didn’t mark. Study Junkie keeps the whole text and builds its questions from the chapter itself.
The questions are written for you. In Readwise, Mastery is “active recall and spaced repetition applied to the notes and highlights you take”, and you write each Q&A or cloze card yourself, with Ghostreader able to help draft them. In Study Junkie, recall questions and problems are generated from the chapter.
There’s also a practice step that Readwise doesn’t have. You can ask for problems on a chapter, work through them with a tutor chat that hints without handing over the answer, and get AI feedback on your written solutions. Recall stays simple: once you switch it on, marking a chapter read schedules sessions on days 1, 3 and 7 by default, and you check your own answer against the one it reveals. It isn’t graded.
The background on why questions beat rereading is in how to remember what you read without taking notes and spaced repetition for books without flashcards.
Pricing works differently too. Readwise is a subscription, from $67.08 to $155.88 a year depending on plan and billing. Study Junkie gives 1,500 free credits after email verification, enough for a book outline plus two chapters with problems and recall, one of them narrated. After that you buy one-time packs that never expire. Details are on the pricing section.
Can you use Readwise and Study Junkie together?
Yes, and for many readers that’s the right answer. Keep Readwise for the long tail: every book and article you read, highlighted and resurfaced for years. Bring the one or two books a year you want to master to Study Junkie, where the full text becomes chapters you can practice on and recall.
The two don’t compete for the same hour. Readwise keeps a broad library from fading. Study Junkie is for going deep on one book. See how Study Junkie works for the full loop from upload to recall.
