TivraX turns any PDF or EPUB on your device into a high-quality audiobook with read-along page sync. Free during the launch window. No uploads. No tracking. Everything happens on-device. WHAT TIVRAX DOES Bring your own book, and TivraX reads it. • Import any PDF or EPUB from Files, iCloud Drive, or the share sheet • High-quality on-device narration: every system voice already on your device works instantly, and a free, optional model download adds neural voices for 12 Indian languages (Hindi, Tamil, Telugu, Kannada, Malayalam, Bengali, Marathi, Gujarati, Punjabi, Assamese, Odia, Nepali) via Parler and natural English via Kokoro • Translate as you listen: read the source page, hear it in your chosen language. Apple Translation works out of the box, and a free on-device AI model (Gemma) adds translation into 30+ languages, including the Indian languages. All on-device, nothing uploaded • Sentence-level highlight tracks the narrator as it reads • Continue where you left off across every Apple device you own CROSS-DEVICE BY DESIGN Render once on your Mac. Listen anywhere. • Mac renders the audio with the highest-quality voices and translation • iCloud Drive syncs everything: books, audio, progress, bookmarks • iPad shows the page and the narration side by side • iPhone for on-the-go listening, in your pocket • Apple Watch for standalone playback: AirPods route automatically, the Digital Crown adjusts volume, and a sleep timer covers bedtime PRIVATE BY DEFAULT TivraX has no servers that store your books. Nothing about your reading is sent anywhere. We can't see what you read because there's nothing to see. • On-device translation via Apple Translation and an optional on-device AI model (Gemma), so your text never leaves your device • On-device speech synthesis, so your text never leaves your device • Sync uses your private iCloud container, not ours • No analytics, no ads, no tracking PERFECT FOR • Long-form technical reading you'd rather listen to during a commute • Language learners: read in one language, hear in another • Anyone with a backlog of PDFs that should really be audiobooks • Readers with vision differences or who prefer audio • Books that exist only as PDFs (textbooks, papers, samizdat fiction) GETTING STARTED 1.
