VidLingo: Video Subtitles dubb

A video translator with subtitle translation, bilingual subtitles, offline subtitles, and video captions in one private, on-device AI app.

Transcribe video to text, generate captions instantly, and export subtitled clips — no uploads, no account, fully offline after model download.

Most translator apps only work off existing captions. We translate live and let you search in your language, with results titled in your language — closing the loop from discovery to understanding.

AI Dubbing

Natural voice-over in 100+ languages. Hear any video in your tongue — movies, courses, Reels, TikToks. Premium neural voices sound human, not robotic. Adjust speed, pitch, emotion. Perfect for blind and sight-impaired users who need audio access to visual content. Tap to play dubbed audio alongside original track. AI dubbing video works on every clip you import.

On-Device AI & Privacy

Transcription runs locally on your device using on-device AI models. Your video and audio never leave your phone — no cloud uploads, no server processing, no tracking. No accounts, no ads, no analytics SDKs. Works completely offline once compact language models download. Your data stays yours.

Offline subtitles

Download models once and generate offline subtitles anywhere — flights, remote areas, roaming-free travel. Language learners review saved lessons on the subway; travelers read local transit videos without data; creators batch-translate entire playlists offline. No connection required after initial setup.

Bilingual subtitles

Students compare structures in real time; polyglots build parallel corpora; deaf and hard-of-hearing viewers get full context without switching tracks. Supports 100+ language pairs.
