BookFab

BookFab AudioBook Creator is a modern AI-powered text-to-speech software designed for Windows users who want to transform written content into natural-sounding audiobooks.



The application focuses on high-quality voice synthesis, EPUB-to-audiobook conversion, and flexible narration controls, making it suitable for authors, educators, content creators, and accessibility users.

Unlike basic text-to-speech tools, BookFab for PC positions itself as a full audiobook production solution.

It allows users to import EPUB files, TXT documents, or pasted text and convert them into professionally structured audiobook formats such as M4B, MP3, or OPUS.

With lifelike AI voices, adjustable narration parameters, and a built-in library manager, the software bridges the gap between simple voice readers and professional audiobook tools.

The software operates on a cloud-based TTS engine, ensuring consistent voice quality and ongoing updates, while still providing a desktop-level workflow for organizing and managing audiobooks locally.

User Interface

BookFab AudioBook Creator features a clean, modern interface designed for both beginners and advanced users.



The layout is divided into clear sections, including Text to Audio, Audiobook Creator, and Library Management. Navigation is intuitive, with large buttons and logical workflows that guide users through each step of audiobook creation.

Text highlighting during playback improves usability, especially for learners and proof-listeners, while automatic scrolling ensures continuous reading without manual interaction.

Overall, the UI prioritizes clarity and productivity rather than overwhelming users with technical complexity.

Installation and Setup

Installing this program is straightforward and quick. After downloading the installer, the setup process guides users through standard installation steps without unnecessary bundled software.

Once installed, users must sign in to activate their license and access cloud-based text-to-speech services.

An active internet connection is required for audio generation, as voice processing is handled on BookFab’s servers.

Initial setup includes selecting default languages and exploring voice options, which can be adjusted later per project.

Highly recommended by the FileHorse review team as an excellent and reliable audiobook creation app.
