Your bookmarks are your desktop.
Kyo.is is a personal web portal where links become your operating system. In a world where CLI and AI compress every entry point—where Notion, Figma, ChatGPT are all just URLs—you don't need to download anything anymore. You just need a place to put them.
No installation needed. Works on any device with a browser.
Native desktop experience with automatic updates.
- ✅ Signed & Notarized - No security warnings
- ✅ Universal Binary - Intel & Apple Silicon
- ✅ Auto-updates - Always loads the latest version from kyo.is
- ✅ System integration - Opens external links in your default browser
Note: The desktop app is a lightweight shell that loads kyo.is. When we update the website, your app automatically gets the new features—no need to download a new DMG!
The moment you open your browser should feel like coming home, not clocking in. Kyo.is embraces blur, stillness, and negative space. It's not a productivity dashboard. It's a room you live in.
A link can hold anything—a tool, a document, a video, an AI assistant. When everything becomes a link, the browser becomes the OS, and your homepage becomes your desktop.
Information doesn't enter your mind through compression and retrieval. It grows through organizing, using, and wanting. Your desire to save a link is the meaning of that link.
