Readwise helps you read more. ZeroMark helps you finish.
Readwise Reader is the best reading and highlighting stack in the category, and it is built to grow a library. ZeroMark is built to empty one: every save read and summarized before you see it, one key per decision, the count only going down.
Who it's for: people paying for Readwise who rarely open it.
What problem: more reading surface makes a backlog easier to keep, not easier to end.
Why different: a library grows. A queue reaches zero.
The model. Readwise Reader: grow a library of articles, PDFs, newsletters and highlights, with spaced repetition on top. ZeroMark: empty a queue: every save decided, the open count only goes down.
What ranks the pile. Readwise Reader: you do, by hand. ZeroMark: your own finish rate, so the saves you actually complete come first.
Deciding. Readwise Reader: click through a list. ZeroMark: one key per save: done, let go, snooze.
AI on your saves. Readwise Reader: Ghostreader answers questions and summarizes any document you open. ZeroMark: a summary before you see the save, and chat over what you kept.
Where keeps go. Readwise Reader: Notion and Obsidian. ZeroMark: Notion and Obsidian.
Hearing what you kept. Readwise Reader: no podcast. ZeroMark: a two-host podcast from the last 30 days of keeps, made in the app.
Price. Readwise Reader: $9.99 a month billed annually, $12.99 a month billed monthly, a 30-day trial and no free tier. ZeroMark: $4.99 a month or $39 a year, 7-day trial.

Questions people ask
Is ZeroMark a Readwise Reader alternative?
For the backlog, yes. For highlights and spaced repetition, no: Readwise is better at that, and we do not pretend otherwise. Many people keep both, one to read, one to reach zero.
Can I use both?
Yes. ZeroMark reads and clears your bookmarks; what you keep can leave for Notion or Obsidian, where Readwise already reads. Nothing on is touched.
