AI Video Translator in the Browser

Captioner is an AI video translator for your videos. Upload your videos and translate right on your browser.

In plain English

Simon Liang's Captioner translates a video inside the browser. You upload the file and the translation happens there, with no separate program to install. The AI writes down the speech, translates it, and can speak the new language while keeping the words in time with the picture. Creators, teachers, and businesses pay by the minute or with monthly credits. The AI does most of that work and the billing, while Simon checks quality, helps users, and handles unusual cases.
