Librera

Librera is a lightweight reading app that helps you import ebooks and novels in a wide range of formats. It also lets you bring in text by scanning, so you can build a personal offline reading library that fits your needs.

To find what you want, you can search by keyword or narrow results by author, genre, or publication date. Once you’ve found a title, you can start reading right away.

Librera also includes an audiobook-style mode powered by an advanced text-to-speech (TTS) engine. You can pick from different voice styles and have the app read content aloud—whenever and wherever you want.
