Download on the Mac App Store
  1. 1

    Install and open the Mac app

    Install CastReader for Safari from the Mac App Store, then open it from Applications.

  2. 2

    Turn on the extension

    In the app, open Safari Settings. In Extensions, select the checkbox beside CastReader. The Mac app helps with setup; reading happens in Safari.

  3. 3

    Allow the page you want to read

    Open an article in Safari and click the orange CastReader toolbar icon. When Safari asks, allow access to this website. Refresh a page that was already open.

  4. 4

    Press play and follow the words

    Click the headphones button on the right edge of the article. Keep the page in view: hear the voice, follow the highlights, and use pause or speed controls whenever you need.

Start with a short article and a free voice. Sign-in is optional for your first read; use Settings → Sign in to restore an existing account.

Something missing?

I cannot see CastReader in Safari

Open the installed Mac app once, then check Safari → Settings → Extensions. If the extension is on but the icon is hidden, use View → Customize Toolbar to add it.

The extension is on, but nothing appears on the page

Allow access to the current website and refresh the tab. Try an ordinary article first; Safari Start Page, browser settings, and protected pages cannot be read.

The page is silent

Click play yourself, check the volume and tab mute setting, and keep the article visible. Check the on-page message for a connection or usage-limit issue.

Help choosing a version

The apps share a product and Pro entitlement, but each surface solves a different extraction and listening problem. Start with the one that matches your source.

Listen to documents and books on a Mac · CastReader for Mac · App Store

Listen to Kindle on Your Phone or Tablet · iPhone, iPad, Android phones and tablets
CastReader is available on iPad and Android tablets, with layouts adapted for a larger reading screen.
Read a webpage, Google Doc, or AI answer in place · Browser extension
The extension works where the page is rendered and can preserve in-page extraction and highlighting on supported sources.
Open a PDF, DOCX, EPUB, image, or copied text · Mobile or upload workflow
Use a document-friendly surface instead of forcing a local file through an ordinary webpage reader.
Use Pro on more than one supported surface · Same login email
Pro entitlement follows the login email. File libraries and reading progress can still vary by workflow and are not promised as universal sync.

I need Google Docs or webpages read aloud

Install the browser extension so CastReader can read the page where it lives.

I want a quick online text reader

Paste text into the Read This to Me tool for instant audio.

I need difficult text read and explained

Use Read & Explain for source-linked guidance at overview, standard, or deep depth.

Sign in with the same email to keep your CastReader Pro status aligned across supported surfaces. Anonymous device allowances do not become a synced Pro account, and content or progress availability can vary by workflow.

Questions about downloading

Is the Mac app the same as the Safari extension?

No. CastReader for Mac is a standalone reading app from the App Store for macOS 14.6 or later. Import documents or open your reading content in the app. CastReader for Safari is a separate extension for reading supported pages inside Safari. Download each from its own card above. The Mac app is free to start, with in-app purchases; it does not promise system-wide selected-text reading.

Does CastReader support iPad and Android tablets?

Yes. The iPad and Android tablet apps are available now. Use the App Store for iPhone and iPad, or Google Play for Android phones and tablets. Check the store listing for current system requirements.

Which CastReader app should I install first?

If your main goal is listening to Kindle books on your phone, start with the iOS or Android app. For supported pages in Safari on a Mac, install CastReader for Safari from the Mac App Store. Chrome, Edge, and Firefox have their own extensions.

Is CastReader available on Android?

Yes. CastReader is available on Google Play for Android and supports mobile read-aloud workflows such as Kindle listening, highlighting, background playback, and AI explanations.

Do I need both the mobile app and browser extension?

Not always. Use the mobile app for phone-first reading and use the extension for browser pages that need in-page extraction and highlighting. Many users install both because they read across devices.

Is CastReader affiliated with Amazon or Kindle?

No. CastReader is not affiliated with Amazon or Kindle. Amazon and Kindle are trademarks of Amazon.com, Inc. or its affiliates.

Can I listen to the voices before installing?

Yes. The CastReader reading voice library uses the same versioned public catalog as supported mobile clients and includes real samples, language status, and Free or Pro tier.
