Create and send tech news digests with RSS, Gemini AI and Gmail

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.
