About this app

ZI² Books is a quiet, beautiful reader for the editions you own. Open a book and it reads like print. Real pages turn under your thumb, the type bends to what your eyes want, and your place is waiting on every device you sign in to.

What you can do:

Read page by page, the way a book is meant to be read, never an endless scroll.
Shape the page to you: size, typeface, weight, line spacing, margins, and justification.
Switch between day and night, let it follow the clock, and trim the brightness without leaving the page.
Highlight in four colors, write a note beside a passage, and export everything you marked.
Listen. Read-aloud carries the text at a speed and pitch you choose.
Find any word inside a book, bookmark a chapter, and jump straight from the table of contents.
Pick up where you left off. Your position, highlights, and settings travel across phone, tablet, and desktop.
Watch your habit grow with a daily streak, time read, and a reading goal you set.

Sign in with your ZI² account to open the editions you own.
