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

• Plain text — paste or type any content
