Key features

Captions that keep up
with the conversation

Whether it's a foreign-language video, an international podcast, or a multilingual meeting, LiveSTT turns speech into readable text the moment it's spoken.

01

Floating subtitle window — always on top

Subtitles appear in a picture-in-picture overlay that floats above all other apps. Scroll your social feed, listen to a podcast, or watch a video — LiveSTT quietly works in the background, streaming transcriptions and translations without interrupting your flow.

02

Powerful offline AI — no API bills

Speech recognition and translation run entirely on your device, powered by Apple Translation language packs.

  • Zero token fees — no hidden subscriptions or third-party AI bills.

Your audio notes and recordings never leave your phone. No internet required, no ongoing API costs — just fast, private, dependable voice-to-text.
