Download FAQ
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. If your reading happens in websites such as Google Docs, Claude, ChatGPT, or Kindle Cloud Reader, start with the browser extension.
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.
