步骤

1. 配置定时触发

   在 n8n 工作流中添加 Schedule Trigger 节点（或从模板导入），设置每 24 小时执行一次。该节点将作为整个自动化的时间入口。

2. 添加 RSS 订阅源

   配置三个 RSS Feed Read 节点，分别读取 VentureBeat AI、TechCrunch AI 和 OpenAI Blog 的 RSS 地址。模板已提供默认 URL，可替换为其他 AI 相关源。

3. 合并并过滤文章

   使用 Merge 节点将三个 RSS 源输出合并，再通过 Code 节点运行 JavaScript：筛选近 48 小时内发布、标题或摘要包含 AI 关键词的文章，去重后按时间排序，最多保留 10 篇。

   // Filter articles from last 48 hours and relevant to AI
   const now = new Date();
   const twoDaysAgo = new Date(now.getTime() - (48 * 60 * 60 * 1000));
   
   // Create a Set to track unique articles (by title or link)
   const uniqueArticles = new Map();
   
   items.forEach(item => {
     const articleDate = new Date(item.json.pubDate || item.json.date);
     const isRecent = articleDate >= twoDaysAgo;
     
     const title = (item.json.title || '').toLowerCase();
     const description = (item.json.description || '').toLowerCase();
     
     const aiKeywords = ['ai', 'artificial intelligence', 'machine learning', 'ml', 'neural', 'gpt', 'llm', 'chatbot', 'automation', 'deep learning', 'agentic ai'];
     const isAIRelated = aiKeywords.some(keyword => 
       title.includes(keyword) || description.includes(keyword)
     );
     
     // Only add if recent, AI-related, and not already added
     if (isRecent && isAIRelated) {
       const uniqueKey = item.json.link || item.json.title;
       if (!uniqueArticles.has(uniqueKey)) {
         uniqueArticles.set(uniqueKey, {
           title: item.json.title,
           description: item.json.description,
           link: item.json.link,
           pubDate: item.json.pubDate || item.json.date,
           source: item.json.source || 'RSS Feed',
           dateObj: articleDate // Keep for sorting
         });
       }
     }
   });
   
   // Convert Map to array, sort by date (newest first) and limit to top 10
   const sortedItems = Array.from(uniqueArticles.values())
     .sort((a, b) => b.dateObj - a.dateObj)
     .slice(0, 10);
   
   // Return formatted items without dateObj
   return sortedItems.map(item => ({
     json: {
       title: item.title,
       description: item.description,
       link: item.link,
       pubDate: item.pubDate,
       source: item.source
     }
   }));

4. 准备文章并检查存在性

   通过 Code 节点将过滤后的文章格式化为单一字符串，包含标题、摘要、来源、日期和链接。随后用 If 节点检查 articleCount 是否大于 0，决定后续走向。

   // Combine all articles into a single string for summarization
   const articles = items.map(item => {
     return `Title: ${item.json.title}\nDescription: ${item.json.description}\nSource: ${item.json.source}\nDate: ${item.json.pubDate}\nLink: ${item.json.link}\n---`;
   }).join('\n\n');
   
   return [{
     json: {
       articles: articles,
       articleCount: items.length,
       processedAt: new Date().toISOString()
     }
   }];

5. AI 摘要生成

   将准备好的文章文本传入 OpenAI 节点（默认 gpt-4.1-mini），使用系统提示词让模型分析多篇 AI 新闻，提取最重要的 2-3 条发展，写成 80-120 词的摘要，适合 LinkedIn 专业人士阅读。

   Now analyze these AI news articles and create a summary covering the most important developments:
   
   {{ $json.articles }}
   
   Focus particularly on major funding rounds, significant product launches, and industry-changing developments from the list above.

6. 生成 LinkedIn 帖子

   将上一步的摘要传入第二个 OpenAI 节点（默认 gpt-4.1-mini），使用系统提示词生成包含钩子、正文、行动号召和话题标签的 LinkedIn 帖子，长度控制在 250-300 词，适合移动端阅读。

7. 邮件发送审阅

   使用 Gmail 节点将生成的帖子以纯文本邮件发送给自己，主题为 'LinkedIn AI Post Ready for Review'。若当天无匹配文章，则走另一分支发送 'No AI News Found Today' 通知。需在节点中配置收件人邮箱地址。

请根据以下材料在 n8n 中搭建工作流：先确认已拥有 OpenAI API 密钥和 Gmail OAuth2 凭证，然后导入模板或按节点清单手动创建。重点检查 RSS 源地址、过滤代码中的时间窗口与关键词、两个 OpenAI 节点的模型选择，以及 Gmail 节点的收件人地址。先用样例数据手动执行一次，确认文章过滤、摘要和帖子生成符合预期后再启用定时触发。
