Morph is the reading app that shapes itself to you. Read, listen, or do both — it adapts to however you want to experience your books. READ WITH FOCUS Import any EPUB and read in a clean, distraction-free reader. Customize your font, theme, and spacing. Highlight passages with smooth, marker-style highlights and save quotes as you go. LISTEN WITH NATURAL AI VOICES Turn any book into an audiobook with AI-powered text-to-speech. Follow along with word-level highlighting that keeps you in sync. Play in the background while you cook, commute, or work out. READ AND LISTEN AT THE SAME TIME Studies show you retain significantly more when you read and listen simultaneously. Morph makes it effortless — just tap play and follow along. Focus mode highlights the current word as it's spoken, so your eyes follow naturally without strain. Less effort, more retention. RSVP (Rapid Serial Visual Presentation) The First RSVP paired with audio to allow you to not only read faster, but have better comprehension, memory and focus! BROWSE THE MORPH STORE Explore hundreds of public domain classics — from Austen to Dostoevsky — curated into collections and ready to download with one tap. Search by title or author, browse by genre, and build your library without leaving the app. New users get a free book to start reading immediately. ASK YOUR BOOKS QUESTIONS Stuck on a concept? Curious about a character? The AI assistant reads along with you and answers any questions about what you're reading, right from the page. TRACK YOUR READING LIFE Set daily goals, build streaks, and see your reading stats over time. Watch your habits transform. YOUR LIBRARY, EVERYWHERE Sync your books, highlights, and progress across all your devices. Pick up exactly where you left off. BUILT FOR READERS, NOT JUST LISTENERS Most TTS apps treat reading as an afterthought — they strip the book down to an audio feed and call it done. Morph was built the other way around. Reading comes first. The text is always beautiful, always yours. TTS is there when you want it, gone when you don't. Switch between reading, listening, or both with a single tap. No mode feels like a compromise. WORKS 100% OFFLINE Morph runs a local AI voice model directly on your device. No internet needed, no streaming delays, no buffering. Import a book, close your wifi, and listen. It just works. MORPH EXCLUSIVE VOICES Custom-built voices you won't find anywhere else. Warm, natural, and designed specifically for long-form reading. Choose from multiple voices or switch to whisper mode — soft, slowed ASMR-style narration perfect for winding down before sleep. IMPORT ANYTHING EPUBs from your device, articles from the web, PDFs — if you can read it, you can Morph it. Import by file, URL, or share sheet. DESIGNED FOR YOUR LIFE Set a sleep timer and drift off to a book. Listen in the background while you drive, cook, or work out. Seamlessly switch between reading and listening without losing your place. Morph fits around your day, not the other way around.
