Audio Captions — Private AI Captions

Live Caption adds accurate, private captions to any browser tab — video calls, lecture platforms, YouTube, Netflix, Udemy, and plain audio/video files — without sending your audio anywhere by default. How it works - Existing captions first: if the page already exposes subtitles (YouTube, Netflix, Udemy, DASH streams), Live Caption reads them directly — free and instant, no account needed. - Local transcription: when no subtitles exist, the free Desktop Companion app transcribes tab audio entirely on your device. Nothing leaves your computer. - Cloud fallback (optional): on machines that can't run the Companion, an entitled Pro/Cloud Pro plan can route short audio chunks through a metered cloud speech engine — clearly labeled in the interface, never chosen silently over the private option. Features - Sidebar caption panel that stays open across tabs - Automatic engine selection: page subtitles → Desktop Companion → cloud, in that order, always visible to you - Local transcript library (up to 50 documents) with search - Optional account sync across devices - On-device translation, plus optional premium translation on paid plans - Works with YouTube, Netflix, Udemy, and generic HTML5 video/audio Privacy Transcription runs locally by default via the free Desktop Companion. Cloud transcription is opt-in, entitlement-gated, and metered — audio is not stored after processing.

Pro (€8/mo) and Cloud Pro (€15/mo) add higher usage caps, translation, and cloud fallback minutes. See https://audiocaptions.com for current pricing.
