This workflow automates the entire lifecycle of collecting, filtering, summarizing, and delivering the most important daily news in technology, artificial intelligence, cybersecurity, and the digital industry . It functions as a fully autonomous editorial engine , combining dozens of RSS feeds, structured data processing, and an LLM (Google Gemini) to transform a large volume of raw articles into a concise, high–value daily briefing delivered straight to your inbox. Read: Full setup Guide ✅ 1. Scheduled Automation The workflow begins with a Schedule Trigger , which runs at predefined intervals. Every execution generates a fresh briefing that reflects the most relevant news from the past 24 hours . ✅ 2. Massive Multi-Source RSS Collection The workflow gathers content from over 25 curated RSS feeds covering: 🔐 Cybersecurity (The Hacker News, Krebs on Security, SANS, CVE feeds, Google Cloud Threat Intelligence, Cisco Talos, etc.) 🤖 Artificial Intelligence (Google Research, MIT News, AI News, OpenAI News) 💻 Technology & Digital Industry (Il Sole 24 Ore, Cybersecurity360, Graham Cluley, and more) ⚙️ Nvidia Ecosystem (Nvidia Newsroom, Nvidia Developer Blog, Nvidia Blog) Each RSS feed is handled by a dedicated node , which ensures: source isolation easier debugging no single point of failure The feeds are grouped using category-specific Merge nodes (Cyber1/2/3, AI, Nvidia), enabling modular scalability. ✅ 3. Unified Feed Aggregation All category merges feed into the Merge_All node, creating a single combined dataset of articles from every source. ✅ 4. Intelligent Filtering (last 24 hours only) The Filter node removes: articles older than 24 hours (based on isoDate ) invalid items duplicated or redundant entries This keeps the briefing strictly relevant to the current day. ✅ 5. Chronological Sorting The Sort – Articles by Date node orders all remaining items in descending date order. More recent or time-sensitive news is therefore prioritized. ✅ 6. Data Normalization (JavaScript Code) A dedicated Code node transforms all incoming items into one clean JSON object : { "articles": [ { "title": "...", "content": "...", "link": "...", "isoDate": "..." } ] } This standardized structure becomes the input for the LLM summarization stage. ✅ 7. AI Editorial Processing – Google Gemini The node LLM – News Summarizer is the workflow’s editorial brain. A complex prompt instructs Gemini to behave like the editor-in-chief of a major tech newspaper , enforcing strict rules: Selection rules: choose only 8–10 truly important stories ignore low-value content (minor product releases, clickbait, rumors…) Relevance criteria: AI research & foundation models Big Tech developments cybersecurity incidents regulation and digital policy semiconductors, cloud, and infrastructure digital rights, governance, sovereignty Deduplication: If multiple feeds report the same story, only one version is kept. Output format: Gemini must output a valid JSON object containing: subject : the email subject line html : a fully structured HTML body grouped into categories Each news item ends with a clickable HTML source link , NEVER plaintext URLs. This step condenses dozens of articles into a polished, editorial-grade briefing . ✅ 8. HTML Newsletter Assembly (Code Node) The Build Final Newsletter HTML node: safely parses the JSON from the LLM cleans any ```json fences or extra text validates subject and html fields embeds the content into a modern, responsive HTML email template The output is a single item containing: the final email subject the final HTML body Ready to be sent. ✅ 9. Automatic Email Delivery The Send Final Digest Email (Gmail node): uses the generated subject sends the curated HTML newsletter delivers it to the configured recipient(s) uses a custom sender name (“n8n News”) The result is a fully automated Tech & AI Daily Briefing delivered with zero manual effort. In Summary: What This Workflow Achieves ✔ Collects news from 25+ high-quality RSS sources ✔ Normalizes, filters, and sorts all items automatically ✔ Uses Google Gemini to select only the stories that truly matter ✔ Generates a coherent, readable, professional-looking HTML newsletter ✔ Sends the result via email every day Perfect for: daily executive briefings technology and cybersecurity monitoring automated newsletter production internal knowledge distribution competitive intelligence workflows
