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
• 53 neural voices across 9 languages: American and British English, Spanish, French, Italian, Portuguese, Japanese, Mandarin, and Hindi
• 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)
• Custom pronunciation dictionary — teach the reader how to say names, jargon, or anything you like
READ YOUR WAY

PRIVACY FIRST
