Lectern is an offline eBook reader for EPUB, EPUB3, PDF, MOBI, AZW, AZW3, FB2 and comics. Read books, listen with text-to-speech, and follow along with synchronized text highlighting. No account, no subscription, and no unnecessary clutter. Just open a book and start reading.

Your library, reading progress and settings stay on your device. Lectern works completely offline unless you choose to connect a sync folder or OPDS catalog yourself.

📚 One eBook reader for every format

Open EPUB, EPUB3, MOBI, AZW, AZW3, FB2, FBZ, TXT and PDF files in a single reading app. Read comics through CBZ and CBR archives. PDFs can be viewed in their original layout, reflowed for easier reading, or listened to with text-to-speech.

🎧 Text-to-speech with synchronized highlighting

Turn any book into an audiobook with built-in text-to-speech support. Follow every sentence with synchronized text highlighting while listening. Control playback from your lock screen, notification panel or Bluetooth headphones. A sleep timer can automatically stop playback at the end of a chapter.

Install natural sounding offline Piper voices in English, Dutch, German, French, Spanish and Italian.

✍️ Comfortable reading for everyone

Customize margins, line spacing, paragraph spacing, font weight, hyphenation and drop caps. Import your own fonts or choose one of the built-in reading profiles:
