AI Subtitle Translation & Captions

Translate subtitle files in 100+ languages with context-aware AI, or turn audio and video into editable captions.

In plain English

This tool translates subtitle files into many languages while trying to keep the meaning of each line, and it can also turn audio or video into captions you can edit. A fresh spoken voice can be added, with the timing kept so the words still match the picture. Creators, teachers, and businesses pay by the length of the media or with monthly credits, because typing and translating every line is slow. The AI does most of the writing, the translation, and the billing. The unnamed person running it still checks quality, helps customers, and handles unusual cases.
