Follow these steps:
- Open your preferred AI tool.
- Start a new conversation or create a new research notebook.
- Click the attachment or upload button.
- Select your PDF file.
- Wait for the tool to process the document.
操作步骤如下：
- 打开你选择的 AI 工具。
- 新建对话或创建研究笔记本。
- 点击附件或上传按钮。
- 选择需要总结的 PDF 文件。
- 等待 AI 完成文档处理。
Before uploading, check the document type. Text-based PDFs are generally easier to process. Scanned PDFs may require OCR (optical character recognition) to convert images of text into machine-readable content.
上传前请检查文档类型。 含有可选择文本的 PDF 通常更容易处理。扫描版 PDF 可能需要 OCR（光学字符识别）技术，将文字图片转换为机器可读取的文本。
For confidential documents, review the AI provider’s privacy and data-retention settings before uploading.
对于包含机密信息的文档，上传前应检查 AI 服务商的隐私政策和数据保留设置。
3. Write an Effective AI Prompt
3. 编写有效的 AI 提示词
Uploading a PDF is only the beginning. The quality of your summary depends heavily on how you instruct the AI.
上传 PDF 只是第一步。摘要的质量在很大程度上取决于你如何向 AI 提出要求。
Here is a reusable prompt you can copy and paste.
下面是一段可以直接复制使用的通用提示词。
PDF Summary Prompt / PDF 总结提示词
Copy Prompt
English prompt

- Verifiable references / 可验证的引用： Page numbers make it easier to check important claims.
4. Generate Different Types of Summaries
4. 生成不同类型的摘要
Not every PDF needs the same summary. Choose the format according to your goal.
不同的 PDF 文档需要不同的总结方式。你可以根据自己的目标选择摘要类型。
Summary format / 摘要类型Executive summary / 执行摘要Key points / 核心要点Study notes / 学习笔记Detailed chapter summary / 逐章总结Critical analysis / 批判性分析
Output language / 输出语言English only / 仅英文中文Bilingual / 中英双语
Copy customized prompt / 复制定制提示词
Examples of when to use each format:
- Executive summary: quickly understand a business report.
- Key points: review a long article in a few minutes.
- Study notes: prepare for exams or presentations.
- Chapter-by-chapter summary: understand a book or manual systematically.
- Critical analysis: evaluate the author’s arguments, evidence, and limitations.
不同类型的摘要适用场景如下：
- 执行摘要：快速了解商业报告。
- 核心要点：在几分钟内掌握长篇文章的重点。
- 学习笔记：备考或准备演示文稿。
- 逐章总结：系统理解书籍或技术手册。
- 批判性分析：评估作者的论点、证据和局限性。
5. Ask Follow-Up Questions
5. 继续提问，深入理解文档
One of the biggest advantages of AI is that you can ask questions after generating the initial summary.
AI 的一大优势是，你可以在生成初步摘要后继续提问。
Try these examples:
你可以尝试以下问题：
| English prompt | 中文提示词 |
|---|---|
| What are the three most important conclusions? | 最重要的三个结论是什么？ |
| Explain this document as if I were a beginner. | 请用初学者能够理解的方式解释这份文档。 |
| What evidence supports the author’s main argument? | 哪些证据支持作者的主要论点？ |
| List all important statistics and their page numbers. | 列出所有重要统计数据及其所在页码。 |
| What information is missing from this report? | 这份报告还缺少哪些重要信息？ |
| Create 10 quiz questions based on the PDF. | 根据这份 PDF 创建 10 道测验题。 |
Pro tip: Ask the AI to identify the relevant page numbers and quote short passages when possible. Then check the original document to confirm that the answer reflects the source accurately.
实用技巧： 尽量要求 AI 标注相关页码，并在适当情况下引用简短原文。随后检查原始文档，确认答案是否准确反映了原文内容。
6. Verify the Summary for Accuracy
6. 检查摘要的准确性
AI summaries can contain errors, omit important details, or misunderstand charts and tables. Always verify critical information before relying on the results.
AI 摘要可能出现错误、遗漏重要细节，或误解图表和表格。在依赖总结结果之前，务必核实关键信息。
Use this checklist:
使用以下检查清单：
Accuracy checklist / 准确性检查清单
0/5Confirm names, dates, figures, and statistics against the original PDF.Check important claims against the cited pages.Review charts, tables, footnotes, and appendices separately.Make sure the summary preserves the author’s original meaning.Identify missing context, uncertainty, and conflicting evidence.
For academic, legal, medical, or financial documents, use AI as a reading assistant rather than a substitute for professional judgment or the original source.
对于学术、法律、医疗或金融文档，应将 AI 视为阅读辅助工具，而不是专业判断或原始资料的替代品。
7. Handle Long or Scanned PDFs
7. 处理超长或扫描版 PDF
Some documents require a different workflow.
某些文档需要采用不同的处理流程。
For long PDFs / 对于超长 PDF：
- Ask the AI to create a document outline.
- Summarize each chapter or section separately.
- Combine the section summaries into one overall summary.
- Ask the AI to check for contradictions or missing topics.
- 先让 AI 生成文档目录和结构概览。
- 分别总结每一章或每个章节。
- 将各部分摘要整合成一份完整总结。
- 让 AI 检查内容之间是否存在矛盾或遗漏。
For scanned PDFs / 对于扫描版 PDF：
- Run OCR if the text is not selectable.
- Check whether the extracted text contains recognition errors.
- Pay special attention to tables, mathematical formulas, and diagrams.
- Upload the processed document and repeat the summarization workflow.
- 如果文本无法选择，先执行 OCR。
- 检查提取的文字是否存在识别错误。
- 特别检查表格、数学公式和示意图。
- 上传处理后的文档，再执行总结流程。
If the PDF contains many images or complex diagrams, ask the AI to analyze those elements separately instead of relying only on extracted text.
如果 PDF 包含大量图片或复杂图表，可以要求 AI 单独分析这些内容，而不是仅依赖提取出的文本。
