LiveCap: Caption & Translate

Turn any sound on your Mac—or your voice on iPhone—into live, translated captions. Runs on device, stays private, and works offline.

LiveCap turns audio into live, readable captions—and translates them in real time.

On your Mac, LiveCap captures the system audio from any app: video calls, online meetings, streaming video, podcasts, lectures, and games. On your iPhone, it captures in-person conversations through the microphone. Either way, you get instant captions you can actually follow.

EVERYTHING ON DEVICE Speech recognition and translation run entirely on your device using Apple's built-in engines. Nothing is uploaded, nothing is kept on a server, and it keeps working offline.

KEY FEATURES • Real-time captions for any sound on your Mac (system audio) or your voice on iPhone (microphone) • Instant translation shown next to the original text • On-device and offline — private by design • Floating overlay keeps captions visible over any app (Mac) • Export transcripts to Word, Markdown, or Notion • Optional AI summaries of what was said • Interface in English, Japanese, and Spanish, with a UI language you can switch independently

GREAT FOR • Following meetings and calls in another language • Watching videos, podcasts, and lectures with captions • In-person conversations and travel • Accessibility and note-taking

ONE PURCHASE, ALL YOUR DEVICES Try it free. Unlock unlimited use with a single one-time purchase that works on both iPhone and Mac (Universal Purchase). No subscription.

Capturing system audio on Mac uses ScreenCaptureKit and asks for Screen Recording permission. Microphone capture asks for microphone access. Captions are generated on device.
