AI reading, for Mac

The reading app that learns how you read.

resage reads alongside you — anchored to your own books, building a picture of how you think, so every explanation fits you better than the last.

Meditations — Marcus Aurelius
Book II

Begin each day by telling yourself: today I shall meet with meddling, ingratitude, and insolence.

They arise from ignorance of what is good and evil. But I have seen the nature of the good, that it is beautiful — and of the bad, that it is ugly.

Nor can any of them injure me, for no one can involve me in what is degrading.

Chat-ready
What does he mean by "good and evil" here?
In this line it's not moral right vs wrong — it's Stoic: the only real good is a well-ordered mind. Last week you asked about prohairesis — this is the same idea, applied to your morning.

The problem

AI can answer anything. It just doesn't remember you.

Knowledge stays fragmented.

You read across a dozen books and papers, but nothing connects. Every new chat starts from zero, with no sense of what you already understand.

Lose your place when the chat resets.

Drop a PDF into a chatbot and the moment the conversation ends, your progress is gone. Re-upload, re-explain, re-attach the file, start over.

Day one

A calm reader, with someone to think alongside.

Not a chatbot with a file attached. A real, full-page ebook you read yourself — with help that stays out of the way until you want it.

Reads alongside you

Turn the pages yourself, like any good ebook. Ask about the page you're on from the bar at the bottom — no commands, no menus to learn.

Anchored to your book

Answers are grounded in the actual text in front of you — not a model's vague memory of it. When it isn't sure, it says so instead of making things up. It matters most with the classics.

One tap to go deeper

A faint ✦ at the end of a line is the only mark on the page. Tap it to open a discussion about exactly that sentence. Quiet, and never interrupting your reading.

Why it gets better

The more you read, the better it fits you.

Generic assistants treat every session as a stranger. resage keeps a private learner model — what you understand, where you got stuck, which explanations actually landed — and it compounds. Day 30 doesn't feel like day 1.

This is the part a general-purpose assistant won't build: a picture of how you learn. To them it's noise. To your reading, it's everything.

Everything it infers lives on one page you can read and edit. Facts it's sure of stay; guesses fade if they aren't borne out. You never manage it — but it's never a black box.

Let resage read the whole book first.

Tap Read full book and resage does a complete read-through on your Mac — scanned pages recognized automatically, no OCR tools to fiddle with.

After that, turn to any page and discuss the entire book, not just what's on screen. A green ✦ marks the books it has read.

The read-through runs locally on your Mac. Your book is never uploaded.

Your books never leave your device.

Your files stay on your Mac and in your own iCloud. Search and read-through run on-device; only the few passages needed to answer a question are ever sent — and used only to answer.

We never train models on your books. Ever.

Private by architecture, not just by policy.

How it compares

Built for reading, not for one-off answers.

Questions

Frequently asked

What is resage?

resage is a Mac reading app with an AI reading companion that learns how you read. You read your own books; it reads alongside you, anchored to the text, and gets more useful the more you use it.

How is it different from ChatGPT or NotebookLM?

Those answer questions statelessly and forget you between sessions. resage keeps a private learner model that compounds across books, and grounds every answer in your actual book instead of the model's general memory of it.

Does it work with my own PDFs and EPUBs?

Yes. Import your own PDF, EPUB, TXT, Markdown or Word files. PDFs keep their original layout; other formats reflow like an ebook.

Are my books private?

Your books stay on your Mac and your own iCloud. We never upload the whole book, and never train models on your content.

What about scanned PDFs?

resage recognizes the text on your Mac automatically, as part of the read-through — no buttons, no tools to fiddle with. It'll flag a scanned page as recognized text, so you know when to double-check.

What languages does it support?

The interface ships in English and Chinese, with more to come. You can discuss books in whatever language you write in.

Does it need my Mac?

Version one is a Mac app. The full read-through — and recognizing scanned pages — runs locally on your Mac. iPhone is coming next.

How much does it cost?

Free to start, with a daily discussion allowance. resage Plus removes the limit. [pricing to be confirmed]
