FAQ
Fenly translates the video's own caption track, which covers the large majority of YouTube videos. If a video has no caption track at all, there's nothing to translate yet, so a small number of caption-less uploads aren't supported.
Only the video's existing caption text is sent to Google Gemini for translation - never your audio or video. The caption text and its translation are not stored on our servers.
