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!

**RC Slate — the browser that opens your documents, built for people who work with AI.** Tap a document link while browsing — Markdown, DOCX (Word), PDF, JSON, YAML, images — and it opens right there, rendered as a clean page. No downloading, no switching to another app, no wondering what a file looks like before you can see it. **Convert anything to Markdown for AI** Turn documents and web pages into clean, token-efficient Markdown — the same content in a fraction of the prompt size. DOCX converts through the app's own parser; web pages by pulling out the article text. Need the images too? Embed them into a single self-contained Markdown file, with quality presets and a live token estimate. Export any view as PDF, PNG, or HTML. (Markdown conversion is not lossless; full page layout is not preserved.) **Read your Obsidian vault** Add a vault folder and read it as it was written — wikilinks between notes and embedded images. Links resolve inside the folder you added, so a note opens the note it points to. And a vault note leaves as one piece: export it as a single self-contained Markdown file with its images embedded, or as HTML, PNG, or PDF — ready to hand to an AI. Reading only; RC Slate never edits or syncs your vault. **A real browser underneath** Documents are grouped by the site they came from. Switch any article to Reader Mode for a clean, distraction-free reading layout with dark mode. iPhone and iPad layouts, with a sidebar and tab strip on iPad. **Clean pages for every format** - Markdown with tables, syntax highlighting, Mermaid diagrams, and LaTeX math - JSON and YAML: colour-coded, with their keys in the table of contents so you can jump straight to one - DOCX (Word) page by page, view-only (the document's own fonts are not included) - PDF and images **Open files from anywhere** Files on your device open from the Files app — or send a file from any app through the share menu, straight to RC Slate. SelfDrop syncs a file across your devices (up to 20 MB per file). **Works offline** Viewing local files works offline on your device.
