OraReader: PDF to Audiobook

Turn any document into a structured audiobook — in seconds.

OraReader converts any PDF, EPUB, or TXT into a fully structured book with automatic chapter detection, then reads it aloud with natural voices and word-by-word karaoke. Drop in a file and start listening before you've finished putting your headphones on.

EVERY VOICE FREE No subscription. No credits. No hourly caps. While other reading apps lock natural voices behind $100+/year, OraReader gives you high-quality neural voices at no cost. Listen all day.

FASTEST DOCUMENT PROCESSING Import a PDF, EPUB, or TXT and OraReader structures it into chapters in seconds — no manual splitting, no waiting. Your book is ready almost instantly.

AUTOMATIC CHAPTER DETECTION Most apps treat your files as one long wall of text. OraReader understands their structure — detecting chapters, titles, and content hierarchy automatically — so you get a real, navigable book instead of endless scrolling.

WORD-BY-WORD KARAOKE Every word lights up exactly as it's spoken — word-level, not sentence-level. Follow along with precision, or tap any word to start listening from there. Natural voices in 60+ languages.

BIONIC READING The first part of each word is bolded, creating visual anchors that pull your eyes through the text faster. Less fatigue, more focus — especially helpful for ADHD and dyslexia. Toggle it on or off anytime.
