Not bad，I like it.
Turns My Kindle Books Into Audiobooks
CastReader works great with Kindle and Google Play Books. It can read my books aloud and basically turn my entire library into audiobooks. Super convenient and easy to use — highly recommended!
Explain is more useful than I expected
The Ai explanation is good when a paragraph is dense. I like that it marks the original instead of replacing it with a generic summary 👍
Won’t replace audible but good for books with no audiobook version
The app is a big buggy and stumbles over contractions and place names. However, it’s way better than having Alexa or Siri read.
It’s obvious it’s AI and it pauses at the end of pages, but it’s usable. For some reason I have not been able to read books when I used to read several a week so audio books are my only option.
Cast reader has allowed me to listen to old favorites without cringing (I have aphantasia so sound quality is extremely important to me without visual images to distract me.)

Kindle sync could be easier
The voices and highlighting are good.
First time Kindle setup was a little confusing though.

Amazing!
I’ve been looking for an app that would help me listen to kindle books FOR YEARS. It works great! A+++
Finally, PDFs that are easy to follow
I used to send every PDF to my Kindle, but with dyslexia I still struggled to keep my place. CastReader’s read-aloud highlighting makes long documents much easier to follow without feeling cluttered. Simple, focused, and genuinely useful.
Finally, a better way to finish Kindle books
I’ve been a Kindle user for years, and CastReader fills a gap I’ve always wanted: a smooth way to listen to my Kindle books while still staying connected to the original text. The synced highlighting makes it easy to follow along, and the resume experience is great for walks, commutes, or when I just want to rest my eyes.
The AI Explain feature is what really makes it stand out. For dense passages, unfamiliar terms, or books that are a bit harder to follow, it doesn’t just read the words aloud — it helps me understand them. It feels like having a reading companion for long-form books.
If you use Kindle a lot and want to actually finish more books, CastReader is absolutely worth trying.
