How can we help?

Resage is a reading tool for macOS with an AI reading companion that learns how you read. You can import your own files, and the companion helps you read and discuss them, getting more useful the more you use it.

The first version of Resage is a macOS app. An iOS version for iPhone is currently in development.

Resage currently focuses on PDF files, preserving their original layout. Support for EPUB, Word, TXT, and Markdown is on the way.

You can read your documents just like a normal e-book. To start a discussion, use the input box at the bottom of the window to ask questions about the current page, or click the subtle ✦ icon at the end of any line to discuss that specific sentence.

When you click "Digest", Resage reads the document locally on your Mac (including automatic text recognition for scanned pages). Once complete, you can discuss and query the entire file from any page.

By default, discussions are anchored to the page you are currently reading. When needed, the AI companion automatically expands its context to the current chapter or the entire file, without requiring you to switch scope manually.

Answers are grounded in the actual text of your files, not the general, vague impressions of an AI model. If the companion is unsure or cannot find the answer, it will state its doubt directly rather than inventing facts, which is especially critical when reading classics or historical documents.

You can adjust the theme, reading background color, and fonts (such as Literata and LXGW WenKai) to make reading comfortable for your eyes.

Resage supports several keyboard shortcuts on macOS:

• ⌘F: Search within the current file
• ⌘+ / ⌘- / ⌘0: Zoom in, zoom out, or reset font size
• ⌘L: Focus on the discussion input box
• ⌘D: Toggle bookmark
• ⌘[: Return to the library
• ⌥⌘T: Toggle the table of contents
• Space / Shift+Space: Page down or page up

The learner model is a private profile representing how you read. It accumulates insights across your documents and files, making Resage increasingly tailormade for you over time.

You can access it by going to Settings → How Resage sees you. On this page, you can review inferred points, edit or delete individual entries, reset the model completely, or turn off memory.

Confirmed behaviors and facts are saved as solid traits. Things the AI guesses about your preferences will fade and drop off if they are not confirmed by your subsequent reading habits. You never have to manually maintain it, and it remains completely transparent.

Your files stay locally on your Mac and in your personal iCloud account if sync is enabled. We do not upload your full documents to our servers, nor do we store them.

Resage only sends a minimal set of relevant text snippets (the current page or passages retrieved by on-device search) to our AI inference provider. This data is processed transiently to generate the response and is discarded immediately.

OCR runs entirely on your Mac to recognize text (supporting over 30 languages). The reading and discussion features support approximately 100 languages.

No. We never use your files, notes, or questions to train any AI models. For more details, please view our full Privacy Policy.

You can start using Resage for free, which includes a daily allowance of discussions. Resage Plus removes this daily limit. Pricing details are [pricing to be confirmed].

You can start using the app anonymously without an account. If you choose to sign in, we support Sign in with Apple, which supports private email relay so we never receive your real email address.

Subscriptions are purchased inside the macOS app and managed through the App Store, where you can handle billing, cancellations, and restoring purchases.

You can delete your account and all associated server-side data at any time from within the app under Settings → Account → Delete Account.

Currently, Resage focuses primarily on PDF documents. Support for other formats is in active development.

Digest runs locally on your Mac, so larger files may take some time. You can let it run in the background and continue with other tasks.

Please verify that both devices are signed in to the same Apple Account and that iCloud Drive sync is enabled for Resage.

The daily allowance resets every day. To continue discussing without any limits, you can upgrade to Resage Plus.
