What is a Tribook?
A Tribook is your ebook, audiobook, and physical book perfectly synchronized. Switch between reading, listening, or both - your progress stays aligned.

Read your ebook with a customizable reading experience
Listen

Scan
Point your camera at any page to instantly sync to that location

AI narration for any ebook
No audiobook? Generate a synthetic narrator that stays locked to your text — the same read-along experience as a synced Tribook. Choose the voice depth that fits the book and your credits.
