Try NowWhat is Celyn?
Celyn is a real-time translation application designed specifically for macOS that integrates directly into the system's notch for a seamless user experience. Developed to provide invisible subtitles, it allows users to understand audio from Zoom calls, YouTube videos, podcasts, or in-person conversations without cluttered windows. The tool solves the problem of language barriers in digital and physical environments by providing instant, on-device translation across 19 different languages. Because it uses Apple's built-in speech and translation frameworks, all processing happens locally, ensuring that audio never leaves the user's Mac. It is ideal for professionals, students, and language learners who require a private, offline, and unobtrusive translation solution. The workflow is simplified to a single hotkey, making it accessible for anyone needing immediate linguistic assistance.
