About Subtitle Translator
Blazing-fast batch subtitle translation for 120+ languages — powered by AI Paste a subtitle file into a general-purpose translator and two things go wrong: the model rewrites your timecodes, and you're doing it one file at a time. Subtitle Translator strips the timing out locally and sends only the dialogue to the engine — the timeline physically cannot be touched — then does a whole season in one drop.
