EasyLect
Read full descriptionHide full description
Follow English-taught lectures with live English transcription and Chinese translation. Review the same class with bilingual notes, audio playback and AI summaries. Follow the lecture as it happens • See English speech transcribed sentence by sentence, with a Chinese translation alongside it. Read the original wording when a technical term matters, and use the translation when you need help keeping up. • Completed sentences stay in the classroom view, so you can look back at the context of something you missed. Adjust the translation text size for a comfortable reading pace. • Pause and resume the class recording as needed. Keep your attention on the lesson, knowing you can revisit the audio afterward. Make sense of key ideas during class • Open the live AI summary to follow the concepts and examples being discussed. Use it to see how the current part of the lecture fits together. • Use question assistance to review a question, its key points and a suggested answer. Switch between the original wording and a translation when that helps you understand what was asked. Review your lesson afterward • Open a saved class from History to browse its English and Chinese transcript along a bilingual timeline. Replay the recording while you review the parts you want to hear again. • Copy and correct transcript text. Export a bilingual, Chinese-only or English-only version of the class notes, or share the audio recording. • Return to saved AI summaries and answers to organize the ideas you want to remember before your next class. EasyLect is made for students studying abroad, university lectures and courses taught in English. It brings the live lecture, the words you heard and your after-class review together, so you can study from the same source instead of reconstructing a lesson from scattered notes. Continued lecture use requires a subscription. Saved class history remains available to read, replay and export. Lecture audio and related text are sent to third-party AI services for processing. Lecture history, recordings and diagnostic data are uploaded to EasyLect's Alibaba Cloud services. Read the Privacy Policy for details.
