SubLocal — Offline Subtitles
SubLocal is an offline video/audio subtitle generator. It runs AI speech recognition entirely on your device to produce SRT subtitles for your videos and audio files — no account, no upload, no internet needed after the one-time model download.
Why do I need to download a model first?
All speech recognition runs on your device for privacy. The recognition model for your chosen language is downloaded once and cached; everything works fully offline afterwards.
Which languages are supported?
Chinese, English, Japanese, Korean, Cantonese, and 25 European languages (model availability varies by language).
Why is my language unavailable on this device?
High-accuracy models for some European languages need devices with more memory (5GB+ RAM).
Where are my subtitles stored?
Only in the app's local storage (History tab). Nothing is uploaded. Exported files stay where you saved or shared them.
