Overview

HushBook is a mobile application designed to enhance the audiobook listening experience by providing synchronized word-by-word text. Unlike traditional audiobook players that only stream audio, HushBook transcribes the spoken words in real-time on the user's device, allowing them to read along as they listen. This feature aims to improve focus, retention, and overall comprehension, especially for those who find it easy to get distracted by audio-only content.

The app supports importing various audio formats, including MP3, M4B, FLAC, and OGG, enabling users to bring their existing audiobook libraries. It also offers a built-in catalog of free public domain audiobooks from sources like LibriVox and the Internet Archive. A key aspect of HushBook is its commitment to privacy; all transcription processes occur natively on the user's phone, ensuring that audio, transcripts, notes, and personal data never leave the device or are uploaded to a cloud server.

HushBook also includes customizable reading profiles to cater to different needs, such as specific fonts (e.g., OpenDyslexic, Atkinson Hyperlegible), color overlays, contrast themes, and adjustable text sizes for users with dyslexia, ADHD, or visual impairments. Users can highlight and save quotes directly from the synchronized text, which are then collected by book and can be shared as formatted cards. The app also offers basic analytics on reading habits, calculated locally on the device, with an optional Pro upgrade for more in-depth insights.
