Hi Product Hunt! 👋 I'm Joey, slave speaker of Caption.im. Super excited to finally share this with you all today. Caption.im started from a very simple frustration: watching videos, online courses, or meetings in different languages is still painful. Subtitles are often missing, translations are slow, and many tools require uploading your audio to the cloud. We thought: what if captions could simply appear everywhere on your screen — instantly? So we built Caption.im, an AI caption window for macOS that can generate real-time subtitles and translations for any audio on your computer. A few things that make it different: ✨ Works across any app — YouTube, Zoom, podcasts, meetings, online courses, etc. 🪟 Floating subtitle window — clean, transparent, and designed to feel native to macOS ⚡ Optimized for Apple Silicon — fast and smooth with very low latency 🔒 Privacy-first — audio can be processed locally with on-device AI models Our goal is simple: make everything on your screen understandable in any language. We’re currently opening the first macOS beta and would love your feedback from the Product Hunt community. 👉 Try it here: https://caption.im Happy to answer any questions about the tech, roadmap, or future plans! 🚀
