Word Hunter

Browser extension that highlights the English words you don't know on any webpage or video.

Browser extensionfree

Word Hunter is a browser extension that highlights English words a learner doesn't yet know on any webpage or YouTube video's subtitles, letting them mark words as 'known' over time so only genuinely unfamiliar words stay highlighted. It's built for English learners who want vocabulary study grounded in what they naturally encounter while browsing, rather than a separate study list.
