About
Live Captions is Apple's native macOS accessibility tool that automatically transcribes spoken audio into readable captions in real time. Integrated directly into macOS (available from macOS Ventura onward), it requires no third-party software, no subscriptions, and no internet connection — all speech recognition runs entirely on-device, ensuring user privacy. The feature works universally across applications: video calls on FaceTime or third-party platforms like Zoom and Teams, streaming services, podcasts, YouTube videos, and even in-person conversations when using an external microphone. A floating, resizable caption window overlays your screen and can be repositioned to suit your workflow. Live Captions is especially valuable for users who are deaf or hard of hearing, those in noisy environments, non-native speakers who benefit from reading along, or professionals who need to follow along during fast-paced meetings. Because it integrates at the system level, it requires no per-app setup and activates from System Settings under Accessibility. The tool supports multiple languages (dependent on macOS version and region), offers adjustable text size and caption window appearance, and works seamlessly alongside other macOS accessibility features like VoiceOver. As a free, built-in feature of macOS, it provides a low-barrier entry to real-time transcription for any Mac user.
