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 reads PDF, EPUB, Word (DOCX), TXT, Markdown, and Kindle files (MOBI, AZW3). PDFs keep their original layout; other formats reflow to fit your screen, with adjustable fonts and sizing.

Yes. You can use our open-source Open in Resage Calibre plugin to send books directly into Resage with one click from your Calibre toolbar or context menu. You can download the plugin (.zip) and load it via Calibre Preferences → Plugins.

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.

On Mac, iPhone, and iPad, newly imported books are uploaded for cloud preparation after you agree to AI data processing. There is no separate cloud-processing switch or local Digest option. Temporary uploaded originals are deleted when processing finishes, or within seven days if it cannot complete. Without AI consent, you can read with lightweight local parsing and no cloud-preparation upload. Existing books are not reprocessed automatically. Once cloud preparation is 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it will state its doubt directly rather than inventing facts, which is especially critical when reading classics or historical documents.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: Find within the current file
• ⌘G / ⇧⌘G: Find next / previous match
• ⌘+ / ⌘- / ⌘0: Zoom in, zoom out, or reset font size
• ⌘L: Focus on the discussion input box
• Tab: Collapse or expand the discussion panel
• ⌘D: Toggle bookmark
• ⌘[: Return to the library
• ⌥⌘T: Toggle the table of contents
• Space / Shift+Space: Page down or page up

Resage remembers what you have read, what you talked about and how you like things explained, across files and conversations, so its explanations fit you better over time.

Your discussions with the AI companion (your questions and the answers), the passages from your files that those discussions quote, and short notes the AI keeps about you. This is stored in your account on our servers until you clear it, delete the file it came from, or delete your account.

Go to Settings → Memory. Turn off Remember My Reading and nothing new is remembered; what was kept before stays until you clear it. Tap Clear All Memory to delete everything Resage keeps about you on the server. On Mac, you can also tick Also clear what Resage remembers about this file when you delete a file. Resage does not currently show you the remembered content itself.

On Mac, iPhone, and iPad, newly imported books are uploaded for cloud preparation after you agree to AI data processing. There is no separate cloud-processing switch or local Digest option. Temporary uploaded originals are deleted when processing finishes, or within seven days if it cannot complete. Without AI consent, you can read with lightweight local parsing and no cloud-preparation upload. Existing books are not reprocessed automatically. Cloud preparation and account cloud sync are separate; disabling account sync does not revoke AI consent. Completed reading bundles and synced books follow the retention controls in our Privacy Policy.

Resage only sends a minimal set of relevant text snippets (the current page or passages found by searching your prepared book) to our AI inference provider. This data is processed transiently to generate the response and is discarded immediately.

Scanned pages are recognized during cloud preparation after AI consent. Recognition and discussion support depend on the language and document; preparation requires an internet connection.

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, with a limited weekly discussion allowance. Resage Plus is US$9.99/month or US$99.99/year and gives you more discussions; Resage Pro is US$29.99/month or US$299.99/year and gives you 3x the Plus allowances. Reading is not charged; discussions, cloud preparation and scanned-page text recognition each have their own allowance.

Only discussions draw on your allowance — importing, reading, read-through and text recognition never do. And not every discussion costs the same: it depends on how much work the AI does to answer you. A quick question about the current page or sentence uses the least. Questions that make the AI search across a whole chapter, the entire file, or several files for evidence — or that require it to enumerate and cross-check carefully (these more complex questions automatically switch to a stronger model) — use a bit more. The AI decides this automatically for each question, so you never have to choose, and normal reading and discussion is nothing to worry about.

Open Settings → Subscription in the app. A progress bar shows how much of your question quota is left, with the time it next resets. The quota resets every week for every account, counted from the day you signed up or subscribed. Cloud read-throughs, cloud storage and device counts are fixed numbers shown on the same page.

Resage requires an account, and signing in is free. There are two ways to sign in. Sign in with Apple supports private email relay, so we never receive your real email address. Or sign in with an email verification code: enter your address, we email you a six-digit code, and you enter it — no password to create or forget. Either way, your account is what keeps your library and subscription when you move to another Mac, iPhone or iPad.

Subscriptions are always purchased inside the macOS app, never on the website. If you use the direct download (.dmg), payment is handled by Paddle, our merchant of record — manage or cancel it from the link in your Paddle receipt email, or email hello@resage.app. If you use the Mac App Store version, manage it in your Apple ID subscription settings. Plus follows your Resage account, so it applies on whichever build you sign in to.

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

Resage reads PDF, EPUB, Word (DOCX), TXT, Markdown, and Kindle (MOBI, AZW3) files. If a file won't import, it may be password-protected, DRM-protected, or corrupted — try re-exporting it without protection, then import again. If it still fails, email us the file details at support@resage.app.

Digest runs in the cloud after AI consent, so larger files may take some time. You can continue reading while preparation runs.

Please verify that both devices are signed in to the same Resage account and that account cloud sync is on in Settings.

Open resage.app/redeem in a browser, sign in with your email, and enter the code. Plus is added to your account and shows up on all your devices. The direct Mac download also has a redeem box under Settings → Subscription. If you already have a paid subscription, a Resage code is declined and stays unused, so you can keep it for later or give it to a friend.

Your allowance refreshes automatically — you can see what you have left and the next refresh time in the app under Settings → Subscription. If you want more discussions, you can upgrade to Resage Plus.
