Hearken
Offline AI audiobooks from your own books and documents
Hearken is an audiobook-style reader that turns your own books and documents into audio using on-device text-to-speech. Import EPUBs, PDFs, Markdown, HTML, FB2, or text files, download a voice model once, and listen offline anywhere — even on a plane. Because narration runs locally on your phone, your books and documents do not need to be uploaded to a cloud TTS service.
Top comment
The main idea is that it works without an internet connection after setup. You download the voice model once, import your book or document, and then the narration runs fully on-device. That means you can listen on a plane, while traveling, or anywhere with no signal.
