ODYSY is a mobile web browser optimized for deep reading through hypertexts. * The main feature of ODYSY is hyperlink preview. After finishing an article, tap the ‘NeXT’ button to explore other articles among hyperlink previews — without leaving your flow. * ODYSY remembers where you paused reading and brings you back to the exact page and spot — just like a bookmark, making it ideal for reading long articles over time. * To share an article, simply swipe left on it in the History list. * You can also highlight impressive phrases of a document. (The most recent highlight on each page will also appear in the history list.) * It’s strongly recommended for reading articles saved in your Safari Reading List or discovered on Twitter, Facebook, and other social media. ODYSY create a space of focus, calm, and intellectual leisure as you read slowly, not hurriedly. It is also suitable for students and lifelong learners who want to explore academic articles, humanities, or even career paths. There are tons of great online media that provide insightful articles. Wikipedia tunneling is also a powerful way to explore the web, discover the world, and feed your intellectual curiosity. Examples of outstanding media: Aeon, Atlantic, Axios, Big Think, Bloomberg, Business Insider, Guardian, Medium, NPR, New York Times, New Yorker, Noema Magazine, ProPublica, Quartz, Rest of World, Reuters, Space.com, TechCrunch, Time, Verge, Vox, The Washington Post, WIRED, and more. However, mainstream browsers like Chrome, Edge, Firefox, Opera, and Safari often provide a distracting experience — not suitable for focused, long-form reading. This is partly due to the inherently scattered nature of hypertext. While hyperlinks offer the advantage of infinite knowledge connectivity, they also make it hard to stay immersed in a single article or topic. That’s why ODYSY is designed to provide a calm, distraction-free reading experience. Unlike traditional browsers, ODYSY is built to support and protect deep reading habits in the digital age. It provides an optimized experience for deep reading of web documents and learning deeply about any topic. It helps you read slowly and deeply within the hypertext environment — enhancing your literacy and preserving your intellectual curiosity. Intellectual curiosity is a core human trait — a driver of creativity, learning, and progress. Reading habits deeply influence how that curiosity grows. Writers and scholars like Maryanne Wolf, David Levy, Ian Leslie, and Nicholas Carr have raised concerns about how digital distractions impair our attention and literacy. They advocate for deeper reading habits in the age of the internet. The web is a sea of knowledge — a vast, endless book, and the most exciting magazine on Earth. Make the best use of it with ODYSY. We support your intellectual journey. Enjoy your deep reading odyssey with ODYSY!
