Opening excerpt (first ~120 words) tap to expand
Kami Subs ✨ Live AI-generated subtitles, overlaid on any browser video, translated into any language — running locally on your machine. Captures the audio of whatever's playing in your browser tab, transcribes it with faster-whisper, translates the output, and overlays it on the video. No cloud, no API keys, no per-minute fees. Works on anything that isn't DRM-protected — YouTube, Twitch, podcasts, lectures, vimeo embeds, news streams. Why this exists Chrome's built-in Live Caption is English-only and doesn't translate. Whisper desktop apps work on files, not live audio. Most "translate any video" tools are paid SaaS that don't work on private content. There's no good free option for "live subs, your language, any video, running on your own GPU." This is that.
