Browser extensionunknownglobal

ThreadIn is a Chrome extension that helps non-native English speakers learn English directly from the comments, posts, and subtitles they already read, translating slang and hidden meaning and tracking vocabulary they've saved. It targets language learners who want to learn from real online content instead of a separate study app.
