LinguaLens: AI Video Translate

LinguaLens turns any video into translated subtitles and natural sounding
voiceover fast, accurate, and privacy minded. It even translates live: a
floating bubble shows instant subtitles for audio playing in any app, in real time.

Video transcription runs on-device, so your video's audio never leaves your
phone. Translation and voice synthesis use secure cloud services over encrypted
HTTPS to deliver human quality results.
