Libretto Audiobook reader with synced text for Mac

Listen to the audiobook.
Read the book.

Your audiobook and the ebook’s own text, in sync, sentence by sentence. On your Mac, from your own files.

Library

Audiobook apps play audio. Reading apps show text. Libretto brings them together.

Libretto is a native audiobook player that shows the book’s original text, the actual ebook, so you follow along with the narration.

Features

Minimal, yet powerful

The book’s original text

Drop in the digital book and Libretto aligns its text to the audiobook.

Two ways to read

One flowing column that scrolls itself, or a typeset spread you turn by hand.

The ink follows the voice

The sentence being read holds the full ink, its neighbours sit a step lighter, and the rest of the page fades as far as you like.

Set the way you read

Any font on your Mac, at the size, measure and spacing you choose. Light, Dark, Sepia, Night — and Zen, for nothing but the text.

Always find your place

Search the whole book. Navigate through your highlights, notes, and bookmarks. Switch between reading and listening without losing your place.

Private by design

Everything happens locally on your Mac.
