Duowei Shijie is an AI platform for turning courses, podcasts, meeting recordings, and foreign-language videos into structured material that can be searched, reviewed, or repurposed. It accepts local audio and video files as well as online links from supported services including Bilibili, Douyin, Kuaishou, Xiaohongshu, Weibo, Zhihu, and Xiaoyuzhou. Results can combine a transcript with chapter summaries, translation, mind maps, and information detected in video frames.
The platform is designed for students, meeting participants, researchers, and media creators, with flashcards, quizzes, meeting templates, and content-conversion tools serving different workflows. A user may start from an official analysis template or define a custom template and prompt that specifies the topics and output structure to extract. Analysis requires registration and either an uploaded local file or a supported public link, while link retrieval and processing depend on the accessibility of the source platform and original media.
