HearSub

Description

HearSub is a Chrome extension designed to enhance the viewing experience on YouTube by offering live subtitle translation and AI dubbing. It supports 13 target languages, including English, Chinese, Japanese, and more, with automatic source language detection. The extension translates subtitles in real-time, providing bilingual captions and synchronized dubbing without the need to upload the entire video. HearSub is optimized for YouTube, ensuring minimal interruption to video playback by preparing and buffering translations and dubbing ahead of time.

Privacy is a priority for HearSub, as it processes only necessary data for caption translation and AI dubbing. Users need only an email address to sign in, and personal data is not sold. The extension runs on Chrome, Edge, Brave, and other Chromium-based browsers, with a Firefox version available. Safari is not supported at this time.

HearSub is currently free for personal use with no usage cap, making it accessible for users looking to enhance their understanding of foreign-language videos. It is particularly useful for open courses, coding tutorials, interviews, podcasts, and news videos, allowing users to grasp key ideas quickly across languages. While HearSub is focused on YouTube, support for additional video platforms is in progress.

The extension does not work offline, as it requires an internet connection for caption translation and AI dubbing. Users can contact support through the feedback feature in the extension, providing details such as video URL and browser version. HearSub continues to improve its translation accuracy by refining its handling of terminology, long sentences, and multi-speaker conversations.
