Turn any PDF or EPUB into a full-cast audiobook — a different AI voice for every character.

Lyraboo is an AI audiobook reader and text-to-speech (TTS) app. Upload your own book and listen: it reads the story, works out who is speaking, and casts a distinct voice for each character — so dialogue sounds like a conversation, not one flat robotic narrator. Or start listening straight away with 1000+ public domain classics built in.

★ FULL-CAST NARRATION, NOT ONE ROBOT VOICE
Lyraboo understands context, emotion and dialogue. Every character gets their own voice, so you never lose track of who is talking. Closer to an audio drama than to standard text-to-speech.

★ PDF TO AUDIOBOOK, EPUB & TXT TO AUDIO
Upload your own ebooks, novels, fanfiction, web serials, documents or study material — PDF, EPUB and TXT — and let the AI narrator read them aloud. Convert PDF to audiobook, PDF to speech and EPUB to audio in minutes — automatic, hands-free, no setup. The first chapter is ready in a minute or two; the rest are made while you listen.

★ A PLAYER LIKE A MUSIC APP, TEXT LIKE SONG LYRICS
Chapters, speed from 0.25x to 3x, background playback with lock-screen controls, and it picks up exactly where you stopped. Under the player the book scrolls with the voice like lyrics: words light up as they are spoken, each line shows who is speaking, and tapping any word jumps there.

★ 1000+ CLASSICS BUILT IN
No files of your own? Dive into a library of public domain classics — Edgar Allan Poe, Jane Austen, Arthur Conan Doyle. Mystery, romance, horror, historical fiction and timeless adventure. No books to buy.

★ MADE FOR LISTENING, NOT SKIMMING
Great for commutes, walks, chores and the gym. Popular with fanfiction and web serial readers, with students working through course material, with readers who have dyslexia or find long documents tiring, and with anyone who takes a story in better by ear than by eye.
