你需要

n8n · serpapi · perplexity · autype · google-drive

步骤

1. 前置准备：配置表单与数据获取

   在 n8n 中导入工作流模板。配置 Market Research Form 节点：表单自动收集 productName（产品名称）、industry（行业）、productDescription（产品描述）、language（报告语言，下拉选项：English/German/French/Spanish）。同时准备三个并行数据源的凭证：Google Trends 节点与 Search Competitors 节点共用 SerpAPI credential；Download Markdown Syntax 节点为 HTTP Request，无需额外凭证，自动获取 https://autype.com/llm-resources/markdown-syntax.md。

2. 合并研究上下文

   Prepare Research Context（Code 节点）将表单数据、Google Trends 近 6 个月兴趣数据、竞品搜索结果（取前 10 条）、Autype Markdown 语法参考合并为单一 JSON 对象，包含 productName、industry、productDescription、language、trendsSummary、competitorSearchResults、markdownSyntax。

   const items = $input.all();
   const form = $('Market Research Form').first().json;
   
   // Extract Google Trends data
   let trendsSummary = 'No Google Trends data available.';
   for (const item of items) {
     const d = item.json;
     if (d.interest_over_time?.timeline_data) {
       const timeline = d.interest_over_time.timeline_data;
       const latest = timeline.slice(-6);
       trendsSummary = 'Google Trends interest (last 6 months):\n';
       for (const point of latest) {
         const value = point.values?.[0]?.extracted_value || 0;
         trendsSummary += `- ${point.date}: ${value}/100\n`;
       }
       break;
     }
   }
   
   // Extract competitor search results
   let competitorSearchResults = '';
   for (const item of items) {
     const d = item.json;
     if (d.organic_results) {
       competitorSearchResults = d.organic_results
         .slice(0, 10)
         .map((r, i) => `${i + 1}. ${r.title}\n   ${r.snippet || ''}\n   ${r.link}`)
         .join('\n');
       break;
     }
   }
   
   // Extract markdown syntax
   let markdownSyntax = '';
   for (const item of items) {
     const d = item.json;
     if (d.data && typeof d.data === 'string' && d.data.includes('Markdown')) {
       markdownSyntax = d.data;
       break;
     }
   }
   
   return [{
     json: {
       productName: form.productName,
       industry: form.industry,
       productDescription: form.productDescription,
       language: form.language || 'English',
       trendsSummary,
       competitorSearchResults,
       markdownSyntax
     }
   }];

3. AI 深度市场研究

   AI Research Agent（AI Agent 节点）调用 OpenRouter Perplexity（模型 perplexity/sonar-pro）。该节点接收合并后的上下文，执行深度市场与竞品分析。需将 OpenRouter Perplexity 子节点连接至 AI Research Agent 的 ai_languageModel 接口。

   =Conduct deep market research for the following product:
   
   **Product:** {{ $json.productName }}
   **Industry:** {{ $json.industry }}
   **Description:** {{ $json.productDescription }}
   
   Here are Google Search results about competitors in this market:
   {{ $json.competitorSearchResults }}
   
   Here is Google Trends data for this industry:
   {{ $json.trendsSummary }}
   
   Based on this data and your real-time web knowledge, provide:
   1. A comprehensive market overview (market size, growth rate, key drivers, challenges)
   2. Identify the top 5-8 competitors and for each: name, website, key features, pricing model, target audience, strengths, weaknesses
   3. Current market trends and predictions for the next 2 years
   4. Where the user's product ({{ $json.productName }}) fits in this landscape
   
   Be specific and factual. Include numbers, percentages, and dates where possible.
   Write in: {{ $json.language }}

4. 准备报告输入

   Prepare Report Input（Code 节点）将 AI Research Agent 的输出（researchOutput）与表单数据、语言、趋势摘要、Markdown 语法参考重新组合，传递给 AI Report Writer。

     }
   }];

5. AI 撰写报告

   AI Report Writer（AI Agent 节点）调用 OpenRouter Anthropic Claude（模型 anthropic/claude-sonnet-4.6）。该节点根据研究数据、趋势数据、Markdown 语法参考及标题页模板，生成 Autype Extended Markdown 格式的结构化市场研究报告。需将 OpenRouter Anthropic Claude 子节点连接至 AI Report Writer 的 ai_languageModel 接口。

   =You are a senior market research analyst writing professional reports.
   
   You MUST write the report using Autype Extended Markdown syntax. Here is the full syntax reference:
   
   {{ $json.markdownSyntax }}
   
   ---
   
   IMPORTANT RENDERING CONSTRAINTS:
   - NEVER use   -- they cannot be processed by the renderer.
   - Page breaks before h1 and h2 headings are inserted AUTOMATICALLY by the rendering engine via the defaults. Do NOT insert manual page breaks (---) before headings.
   - For blockquotes (> syntax), you may ONLY set `color` and `borderColor` as inline attributes. Example: `> {color=#1e40af borderColor=#3b82f6} Key takeaway text here`. Do not set background, padding, indent, or other blockquote attributes.
   - Use standard Markdown horizontal rules (---) ONLY for visual separation where no heading follows, since headings already force page breaks.
   
   Report structure (use these exact sections with ## headings):
   1. Executive Summary
   2. Market Overview (size, growth rate, key drivers)
   3. Trend Analysis (include Google Trends data interpretation)
   4. Competitive Landscape (table comparing competitors)
   5. SWOT Analysis (use a table for the user's product)
   6. Key Findings & Recommendations
   7. Sources
   
   Formatting rules:
   - Use ## for main sections, ### for subsections
   - Use tables (with :::table wrapper for styling) for competitor comparisons and SWOT analysis
   - Use **bold** for key metrics and findings
   - Use > blockquotes for key takeaways (only with color and borderColor attributes)
   - Use numbered lists for recommendations
   - Keep the report between 1500 and 3000 words
   - Be factual and specific -- include numbers, percentages, and dates
   - Do NOT wrap the output in markdown code fences
   - Output ONLY the markdown content, nothing else

6. 渲染 PDF 与输出

   Prepare Render Payload（Code 节点）清理 AI 输出（去除代码围栏），生成文件名格式为 market-research-{slug}-{YYYY-MM-DD}.pdf。Render Report PDF（Autype 节点）使用 Open Sans 字体、专业标题层级（h1 28pt/h2 22pt/h3 18pt）、自动分页、图表配色、页眉页脚等默认样式将 Markdown 渲染为 PDF。最后 Save Report to Drive 节点上传至 Google Drive；需将 folderId 从 YOUR_FOLDER_ID 改为实际目标文件夹 ID。

你是一个 n8n 工作流搭建助手。用户想复现「自动生成 AI 市场研究报告」模板。请按以下顺序协助：
1. 确认用户拥有自托管 n8n 实例（社区节点必需）；
2. 检查已安装 n8n-nodes-autype 与 n8n-nodes-serpapi；
3. 引导创建四个凭证：SerpAPI、OpenRouter（两份，可同 key）、Autype API key、Google Drive OAuth2；
4. 导入 workflow JSON 后，逐节点检查凭证分配；
5. 提醒将 Save Report to Drive 节点的 YOUR_FOLDER_ID 替换为实际文件夹 ID；
6. 建议首次运行前用测试数据验证各节点输出。
