## What it is
Readest is an open-source, cross-platform ebook reader built with Next.js and Tauri v2, supporting EPUB, PDF, MOBI, AZW3, FB2, CBZ, and more. It offers annotations, split-screen parallel reading, text-to-speech, translation, OPDS/Calibre integration, and cross-device sync of progress and highlights.

## Use cases
- read epub and pdf books on all my devices
- listen to ebooks with text-to-speech
- read two books side by side for translation study
- sync reading progress and highlights across devices
- connect an ebook reader to my calibre library or OPDS catalog
- export highlights to readwise
- translate passages while reading without leaving the app

## When to choose
- you want one modern ebook reader across desktop, mobile, and web
- you need annotations, TTS, translation, and sync in a single app
- you want an open-source Foliate successor with OPDS and Calibre support

## When to avoid
- you need DRM-protected Kindle store books (only unprotected formats are supported)
- you prefer a minimal reader without cloud sync or extra features
- you need an e-ink-optimized reader like Koreader on dedicated devices
