Translate YouTube titles, descriptions, hashtags and subtitles into 100+ languages in one click
Translate titles, descriptions and hashtags into over 100 languages — including regional variants like Latin-American Spanish and Brazilian Portuguese — in a single job that runs in the background.
Translations publish as YouTube localizations, so each viewer sees your title and description in their own language. Your original text is never changed; links, timestamps, @handles and brand hashtags are preserved.
VidAI enables YouTube's own auto-translate for every language you pick, so subtitle translation costs 0 credits, provided the video already has subtitles in its source language.
AI Council drafts title options with several models and a judge model picks the strongest; one click generates descriptions, tags, hashtags, keywords and chapters; AI comment replies are drafted in the viewer's language without leaving Studio.
