Aya Reader: A Cross-Language Swiss Army Knife for ReadersAya Reader: The Cross-Language "Swiss Army Knife" for Readers In an era of information equity, great ideas should not be constrained by language barriers. As e-readers become increasingly bloated and digital bookshelves grow more ornate, Aya Reader chooses to step back. We offer no flamboyant flourishes or crowded decorations. Aya is a pure "Swiss Army Knife" built for a singular purpose: removing the two biggest obstacles in reading—language boundaries and eye fatigue. 1. Global Original Works, Rendered in Your Native Tongue We believe translation should not be an interruption; it should be an extension of cognition. Bridge the Language Gap: No matter the source language, Aya Reader brings it into your native tongue with translation that is always within reach. Full-Chapter Semantic Flow: Leave fragmented word lookups behind. Our deep, full-chapter processing preserves paragraph logic and reading rhythm, allowing you to absorb global knowledge as fluently as a native text. 2. Natural, Life-like Narration (TTS) To liberate your eyes, we have refined the Text-to-Speech experience with obsessive care. Top-Tier Voice Engines: Integrated with EdgeTTS and native iOS voices, Aya provides a natural, "breathable" listening experience that remains stable and pleasant over long sessions. Viewport-Level Precision: A unique "Non-Auto-Flip" logic and a "Return to Current Position" button ensure your eyes always stay in perfect sync with the audio. True Background Playback: With deep support for Audio and AirPlay, your reading continues seamlessly during commutes or moments of rest, even with the screen off. 3. A Pure Tooling Foundation Universal Format Support: Gracefully handles EPUB, PDF, and TXT to cover your primary reading workflow. System-Level Integration: Forget heavy file shuffling. Aya respects your storage and instincts—simply tap a file in any app to launch it directly via the system "Open" action. The Beauty of Detail: From panel translucency to precise speech-rate increments and sleep timers, every UI adjustment exists to make the tool disappear and let the text emerge. Product Manifesto Aya Reader does not want to change how you read. It simply wants to smooth out the boundaries of language and stay with you through those hours of deep, uninterrupted focus. If you are tired of complex setups and redundant features—if you only want to finish a book with undivided attention or quietly listen through a translated chapter—then this "Swiss Army Knife" was made for you.If you are tired of complex setup and redundant features, and you only want to finish a book with undivided attention or quietly read through a translated chapter, then this Swiss Army knife was made for you.

Cadence helps you stay with what you're reading. The page fills in word by word at the pace you set, so your eyes always know where to go, and there's never a wall of words waiting. STAY FOCUSED The words arrive in the order you read them, at a steady pace. Your eyes follow along, and the pace carries you on when your mind would wander. Tap anywhere to pause. NEVER OVERWHELMED Each page starts empty and fills as you read. Only the words you've reached are on the screen, so there's nothing ahead to skim and no place to lose. When you'd rather see it all, the full text is a tap away. A PAGE THAT SUITS YOU Tell Cadence what makes reading harder, if anything, and it suggests a font, size and background that some people find easier. Choose your own pace, in light or dark, and change any of it whenever you like. STAY WITH IT Set a daily reading goal, get a gentle reminder if you'd like one, and watch your week fill with the books you read. Highlight what you want to keep, and find it again later.
