Zhihu Direct Answer

Zhihu Direct Answers is a feature of ZhihuAI searchA knowledge-based reading tool that answers questions by combining content from Zhihu, online resources, and expert sources, and supports further research based on documents or knowledge bases. It is ideal for researching the background of a question, comparing different viewpoints, and organizing materials already collected on a specific topic.

From Searching to Selective Reading

You can type in your question and ask follow-up questions, or you can upload files to read through the specified materials. For tasks that require more specific evidence, specialized searches, in-depth reading of individual articles, and Q&A based on designated sources can narrow the scope of discussion and reduce the need to repeatedly search through large amounts of irrelevant material.

When using this tool, you can first ask for the overall conclusion, then follow up by asking about the evidence supporting the conclusion, differing viewpoints, or unresolved issues. It is important to distinguish between the source material and the generated answer: the author’s views and research findings in the source may not necessarily be on the same level as the AI’s inferences.

Personal Knowledge Base

The knowledge base can organize personal files, webpages added via browser extensions, and synchronized Zhihu bookmarks. When asking a question, you can choose either the professional knowledge base or your personal knowledge base as the search scope, allowing answers to be based on existing information.

The public knowledge base page provides a “Ask a Question in This Knowledge Base” link, and the Q&A feature supports files such as PDFs, Word documents, PowerPoint presentations, spreadsheets, and text files. A knowledge base is well-suited for the long-term accumulation of information on a specific topic; however, users are still responsible for ensuring that the content remains complete, up-to-date, and free of contradictions.

Zhihu content can offer insights and perspectives, while professional sources provide leads for further research; AI synthesis does not automatically eliminate bias in sources. When dealing with research citations or important decisions, you should refer back to the original text to verify the timing, context, and evidence, and avoid relying solely on the generated conclusions.
