This workflow collects your Google Alerts, reads the articles for you, and compiles a single, clean AI-summarized briefing.\n\nUse cases: Create daily executive briefings on competitors, track industry trends without reading clickbait, or monitor brand mentions efficiently.\n\n### How it works\n* **Ingestion:** The workflow fetches unread \"Google Alerts\" emails from your Gmail account.\n* **Extraction:** It aggregates the emails and uses a custom Code Node to extract the specific article links and topics, filtering out Google's tracking redirects.\n* **Scraping & Cleaning:** It visits every article link to retrieve the content. A smart \"Cleaning\" node strips away ads, scripts, and unnecessary HTML to ensure high-quality data and reduce AI token costs.\n* **AI Analysis:** Google Gemini reads the cleaned text and generates a concise 2-4 sentence summary for each article.\n* **Reporting:** The workflow compiles all summaries into a professional, responsive HTML table, sorted alphabetically by Topic.\n* **Delivery:** You receive **one** single digest email containing all the news.\n* **Cleanup:** The original Google Alert emails are automatically marked as \"read\" to keep your inbox zero.\n\n### How to use\n* **Setup Trigger:** The template uses a Manual Trigger for testing. For production, replace this with a **Schedule Trigger** (e.g., every morning at 7 AM) or a **Cron Trigger**.\n* **Gmail Configuration:** Ensure the `Get many messages` node is set to filter for `sender:googlealerts-noreply@google.com`.\n* **Prompt Customization:** You can adjust the system prompt in the AI Agent node if you prefer bullet points or a specific language for your summaries.\n\n### Requirements\n* **Google Gemini API Key:** To power the AI summarization (using the `gemini-2.5-pro` or similar model).\n* **Gmail Account (OAuth2):** Required for both reading the alerts and sending the final digest.\n\n### Need Help?\nreach me under [berni@zindel.digital](mailto:berni@zindel.digital?subject=N8N%20Google%20Alerts%20Template)" }, "typeVersion": 1 }, { "id": "600eef50-d2c1-42c2-8545-2ffee2009542", "name": "Sticky Note10", "type": "n8n-nodes-base.stickyNote", "position": [ -400, 368 ], "parameters": { "color": 4, "width": 1024, "height": 544, "content": "# 1.
