BridgeSub
Bilingual subtitles for the films you already own.
Two languages, one track.
Merge two subtitle tracks by timing or by meaning, compare both results side by side, and keep the better one.
Timed to the dialogue.
BridgeSub listens to the soundtrack with speech recognition that runs on your Mac, and lines the subtitles up with it. Your film and its audio never leave your Mac.
Fill in the missing language.
Translate with Ollama, or with any OpenAI-compatible service. Your key stays in the macOS Keychain, and nothing is sent until you confirm.
Catch problems before you export.
BridgeSub scores the alignment and the translation, so weak spots show up before you save.
Ready for the way you watch.
Save SRT, WebVTT, or ASS files, or build a new MKV or WebM with the subtitles inside. Your original file is never touched.
