What's New in Sandbook

1.1.2

November 1, 2026

Select any text to look up a word or translate it, and export a book's bookmarks as a text or Markdown file. Word highlighting is more reliable, and a scene break at the end of a chapter now moves straight on to the next one. If something goes wrong, Settings › Copy Diagnostic Info helps us fix it.

Best really free AI ebook reader

Using the same AI voice generator as most other Al readers (Kokoro), Sandbook is a really free and very nice reader.
It is stable, it does the job fairly well regarding the AI voice generator model.

Edit : even better now it continue reading in the background (locked screen)

Response from developer

Thank you! You're right, it's Kokoro underneath; my part is making it run well on the phone itself. The new version, 1.0.9, keeps reading when you lock your phone and is about half the download size. And if you also read in French, the French voice is in the voice list under Français.

This just made multiple apps irrelevant

This app is a complete game changer. Upload your books in any format and it becomes an audio book platform that allows you to listen and read along anywhere. I flew through 2 books in 2 days just because I can just continue listening where I left off reading while driving or doing other things. Made 3 of my main book apps instantly irrelevant.

Response from developer

Thank you! Listening in the car and picking up exactly where you stopped reading is what I hoped Sandbook would do, so this made my day. Enjoy the next books!

Best app for audio book lovers

Really enjoyed the app, I love to hear the audio book instead of reading, and it’s highlighting feature is good, able to track where we are in that page, one bug is sometimes it lost high lighting features need improvements, and in future version make the overlay or something to make notes or annotate over the pdf or text source it will be helpful,apart from that, it’s is really helpful and I enjoyed it

I ADORE this app

Has been a lifesaver in terms of studying. Made less interesting subjects much easier to get through, nice voice selection and FREE which I appreciate so so much especially with everything being so expensive, this app has really helped.

Response from developer

Update: since version 1.0.9, Sandbook keeps reading when you lock your phone, so there's no chapter to prepare anymore. Just press play and lock it. I'm so glad it's helping you study; good luck with your courses!
