Choose the video to localize and the subtitle/dubbing language you want.
Use the Windows one-click installer, clone the repo, or build the Docker image.
Set the LLM, ASR and TTS providers and keys in the configuration before the first run.
Start the app, drop in the video, and let it cut, translate, align and optionally dub.
Splits subtitles at natural sentence boundaries for readable, Netflix-style timing.
Translates subtitles and aligns them to the audio so lines land where they are spoken.
Adds dubbed audio, with voice-cloning demos based on CosyVoice and GPT-SoVITS.
Can produce dual-language subtitle output for language-learning and accessibility use.
Lets you choose among multiple LLM, ASR and TTS providers in configuration.
An API mode (start.py --api) replaces the old Excel batch mode for automation.
Get the source code from GitHub and enter the project directory.

Yes - VideoLingo is Apache-2.0 licensed and free to use.
It orchestrates LLM, ASR and TTS providers; cloud providers need your own API keys, while local options can avoid per-call costs.
Compared with basic auto-subtitle tools, VideoLingo focuses on the full craft - cutting, translation quality, alignment and dubbing - rather than just raw transcription.
Clone the repo, run uv run start.py (or the one-click installer on Windows), configure your providers, and process a short video first.
