CastReader

CastReader is an app that reads content out loud. It handles web pages, PDFs, and Kindle books, and it highlights the text as it speaks so you can follow along. Nine languages are supported, and the app runs on iOS, iPadOS, Android, Chrome, Edge, and Firefox, so the same material can move between your phone, your tablet, and your browser. The listing is clear that it is a standalone product and is not associated with Amazon or Kindle, even though it can read Kindle books. There is a free version and a paid Pro version, so you can try the reading experience before deciding whether the extra features are worth paying for.

- Listen to a web page while doing something else

- Follow a PDF with highlighting as it reads

- Use it as reading assistance when text is hard to read

- Switch between the nine supported languages

- Commuters who want to listen instead of reading on a small screen

- Readers who like audio paired with visual highlighting

- People who need reading assistance for long documents

Only nine languages are supported, so coverage is limited if you read in something else. Some features sit behind the paid Pro version, which means the free tier is an entry point rather than the full product. Because it runs across phones, tablets, and several browsers, behaviour can differ between them, so test it on the device you plan to use most. Free tier rules and pricing can change, and since the app is independent of Amazon, any Kindle support is handled separately from Amazon's own services.
