Utilizing OpenAI Embeddings technology, our smart document retrieval system offers you a one-stop school information search service. Whether it's regulations, course descriptions, or class selection information, you can quickly find what you need with just one click, without the hassle of searching on various platforms.
Regulations, Campus Information, Available Anytime
Using Embeddings technology, we convert school documents and user queries into numerical vectors, then perform fast and accurate information retrieval in vector space based on semantic similarity.

If you have other questions, feel free to ask us
Why can't I find the content I'm looking for?
BDFZ AI builds a text index from school-related documents in the database, so if the content related to your question is not explicitly stated in school documents, it cannot return accurate answers. Additionally, you can try changing the way you ask your question, for example, use 'Academy activity room' instead of 'Book activities'. If you still can't find an answer, you can click the button to submit feedback.
Why can't I find some content about Dalton College?
Most of Dalton College's documents, including course manuals and course selection guides, are in English. Therefore, based on actual testing, asking questions in English usually yields better results than in Chinese.
Is BDFZ AI free?
BDFZ AI is free for school teachers and students who have an @i.pkuschool.edu.cn email address. There are no plans to open it to the public in the beta version.
How do I search for specific files or documents?
You can search for specific files by clearly stating the file name in your question. When asking, please be as specific as possible about the content you want to search for and use relevant keywords to help the system accurately match your needs.
Can BDFZ AI guarantee the accuracy of search results?
BDFZ AI strives to provide accurate search results by building text indices and using advanced semantic matching technology. However, due to updates and changes in school documents, we cannot guarantee that all information is up-to-date and complete. We recommend verifying important information again and referring to official channels.
