Unknown app

Unknown turns dense reading into listening. Your Mac creates a natural narration for any PDF or EPUB, and this app puts that narration in your pocket. LISTEN ANYWHERE Every book and paper you process in Unknown for Mac appears on your iPhone automatically, with the same lifelike voice. READ ALONG ON THE REAL PAGES The actual pages render on screen while the current paragraph lights up in sync with the audio. Swipe to a page and the audio follows. YOUR WHOLE LIBRARY, IN SYNC Progress, bookmarks, notes and mind maps sync both ways through your own iCloud. Pause on the Mac, resume on your iPhone. FIND PAPERS ON ARXIV Search arXiv from the app, read any paper instantly, or queue it so your Mac narrates it for you. MIND MAPS Maps generated on your Mac arrive with each book: the whole argument at a glance. PRIVATE BY DESIGN Your books sync through your own iCloud. No servers of ours ever see them. BUILT FOR LISTENING Background audio with lock screen controls, adjustable speed, 15 second skips, and paragraph by paragraph highlighting. Unknown for iPhone includes a sample book so you can try the experience right away. Creating audio for your own books requires the Unknown app for Mac (unknown.ac).
