## Overview

- **Who it's for**: Readers who juggle books, PDFs, and documents across many formats — students, professionals, language learners, and casual book enthusiasts who want one app instead of several.
- **What you get**: A free, ad-free reader supporting EPUB, PDF, MOBI, AZW3, FB2, DOC/DOCX, RTF, ODT, TXT, DjVu, and comic formats (CBR/CBZ). It organizes large libraries into custom collections with author/series grouping, and adds bookmarks, highlights with notes, full-text search, dictionary and translation lookups, adjustable fonts and themes (day/night/sepia), and text-to-speech. Works fully offline with automatic reading-progress sync.
- **How it works**: Point ReadEra at your device storage (or import files) and it auto-detects and catalogs your e-books and documents into a searchable library; open any file to read, annotate, and pick up where you left off across sessions.
