步骤

1. 配置 Webhook 触发器与输入源

   在 n8n 中添加 Webhook 节点，方法设为 POST，路径设为 meeting-transcript。将生成的 URL 配置为 Zoom、Google Meet、Otter.ai 等服务的 webhook 端点，或创建手动提交表单。支持 JSON、form data 等多种输入格式。

2. 配置 OpenAI 分析节点

   添加 OpenAI 节点，选择 Chat 资源，配置 API 凭证。模型选 GPT-4 或 GPT-3.5-turbo，temperature 0.3，max tokens 1500。节点包含 system prompt 定义输出 JSON 结构，以及 user prompt 模板注入会议元数据与转录文本。

3. 配置智能合成与评分代码节点

   添加 Code 节点（Synthesize Intelligence），运行 JavaScript 计算行动项优先级分数（0-40 范围）和会议完整度评分（0-100）。代码解析 OpenAI 返回的 JSON，为每个行动项生成唯一 ID、排序，并标记未分配任务。可根据需要调整阈值。

   const meetingData = $('Parse Meeting Input').first().json;
   const aiResponse = JSON.parse($input.first().json.choices[0].message.content);
   
   // Calculate priority scores
   function calculatePriorityScore(actionItem) {
     const priorityScores = { 'High': 3, 'Medium': 2, 'Low': 1 };
     const hasOwner = actionItem.owner && actionItem.owner !== 'not specified' ? 1 : 0;
     const hasDueDate = actionItem.due_date && actionItem.due_date !== 'not specified' ? 1 : 0;
     return (priorityScores[actionItem.priority] || 2) * 10 + hasOwner * 5 + hasDueDate * 5;
   }
   
   // Enrich action items
   const enrichedActionItems = aiResponse.action_items.map((item, index) => ({
     id: `${Date.now()}-${index}`,
     task: item.task,
     owner: item.owner || 'Unassigned',
     due_date: item.due_date !== 'not specified' ? item.due_date : '',
     priority: item.priority,
     priority_score: calculatePriorityScore(item),
     status: 'Not Started',
     meeting_title: meetingData.title,
     meeting_date: meetingData.date,
     created_at: new Date().toISOString()
   }));
   
   // Sort by priority score
   enrichedActionItems.sort((a, b) => b.priority_score - a.priority_score);
   
   return {
     json: {
       // Meeting metadata
       meeting_id: `meeting-${Date.now()}`,

       completeness_score: calculateCompletenessScore(enrichedActionItems, aiResponse)
     }
   };
   
   function calculateCompletenessScore(actionItems, analysis) {
     let score = 50; // Base score
     
     // Penalties
     if (actionItems.length === 0) score -= 20;
     if (actionItems.filter(a => a.owner === 'Unassigned').length > 0) score -= 10;
     if (actionItems.filter(a => !a.due_date).length > 0) score -= 10;

     if (analysis.next_steps.length > 0) score += 10;
     if (actionItems.every(a => a.owner !== 'Unassigned')) score += 15;
     if (actionItems.every(a => a.due_date)) score += 10;
     
     return Math.max(0, Math.min(100, score));
   }

4. 配置 Slack 摘要推送

   添加 Slack 节点，认证方式选 OAuth2，创建 Slack app 并授予 chat:write 权限。将频道 ID 占位符替换为实际频道（如 #meeting-summaries）。消息模板使用 mrkdwn 格式，含会议摘要、决策、行动项和完整度评分。

   {{ $json.action_item_count > 5 ? `\n...and ${$json.action_item_count - 5} more` : '' }}
   
   {{ $json.has_unassigned_tasks ? '⚠️ *Warning:* Some tasks are unassigned' : '' }}
   {{ $json.recording_url ? '🎥 <' + $json.recording_url + '|Watch Recording>' : '' }}

5. 配置 Notion 数据库同步

   在 Notion 中创建两个数据库：Meeting Notes（字段：title, date, attendees, summary, action items, completeness, recording URL）和 Action Items（字段：title, assigned to, due date, priority, status, meeting relation）。共享给集成，添加 Notion token。配置 Create Meeting Note 和 Create Task in Notion 节点，填入数据库 page ID。

6. 配置邮件通知与日历提醒

   添加 Gmail 节点，配置 OAuth2 或 SMTP 凭证。邮件模板为 HTML，含优先级颜色标识和会议上下文。添加 Google Calendar 节点，启用 Calendar API，在行动项截止日期当天 9:00 创建提醒事件（可调整），将任务责任人添加为参与者。

   <hr>
   <p style="font-size: 12px; color: #666;">This action item was automatically extracted from the meeting transcript using AI.</p>

7. 配置分析追踪与测试验证

   创建 Google Sheet，列名：Meeting_ID, Title, Date, Attendees, Duration, Action_Items, High_Priority, Decisions, Completeness, Unassigned_Tasks, Follow_Up_Needed。配置 Google Sheets 节点追加数据。用 POST 发送样例转录文本测试，验证 Slack 消息、Notion 条目、邮件、日历事件和 Sheets 记录。
