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.

---

✅ 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.
