在 YouTube 语境中学习单词、词组和俚语，点击回看、记录笔记并回到原句复习。

Learn English from the YouTube videos you enjoy. EnglishHelper helps you discover useful words, phrases, slang, and idioms in context—and save them for practice later. • Personalized vocabulary: Get AI-powered recommendations based on your learning level, interests, and the expressions you already know. • Learn in context: See pronunciation guides, definitions, the original sentence, and Chinese translations. • Preview before watching: Review expressions one at a time before starting your video, while keeping the full list available in the sidebar. • Follow along: See vocabulary reminders on the video when an expression appears. Replay the relevant segment to hear it again. • Build your Notebook: Save expressions with their original video and timestamp. Jump back to the relevant moment whenever you want to review. • Practice your own sentences: Write a sentence—or use your computer’s voice typing—and receive AI feedback. Repeat the exercise as often as you like. • Keep recommendations relevant: Mark easy expressions as already known so future recommendations better match your needs. Sign in with Google to access your personal Notebook and known vocabulary across devices. EnglishHelper currently provides Chinese explanations and translations for English learners. An account is required, and new users need an invitation code from the administrator. Video analysis depends on available captions or supported transcription. Relevant transcript text and learning preferences are processed by the configured AI service to generate recommendations.
