## Description

Turn any article, ebook, or PDF into natural speech. 53 neural voices across 9 languages — fully on-device. No cloud, no tracking, no subscriptions.

KO Reader turns web articles, ebooks, and PDFs into natural-sounding speech — entirely on your device. No cloud, no tracking, no subscriptions.
Paste a URL or open an EPUB or PDF, and KO Reader reads it aloud with a neural AI voice. Everything runs locally, so your reading stays private and works anywhere — on the train, on a plane, or off-grid.  Export your favorite articles or books to m4a or m4b files. 

WHAT YOU CAN READ

 • Web articles — Wikipedia, news sites, blogs, and Substack
 • Fanfiction — Archive of Our Own, Royal Road, and Wattpad, with chapter detection
 • EPUB ebooks with full chapter navigation
 • PDF documents
 • Plain text — paste or type any content
 • Safari Share Extension — send articles to KO Reader with one tap

 NATURAL AI VOICES

 • Preview any voice before selecting it
 • Mark favorites for quick access
 • Playback speed from 0.5x to 2.0x
 • Smart heteronym resolution — the voice knows the difference between "lead" (the metal) and "lead" (to guide), "wound" (injury) and "wound" (past of wind)

 PRIVACY FIRST
