Daily tech & cyber security brief with RSS, OpenAI GPT-4o, and Gmail

What this workflow does --------------------------- - Pulls free security/tech headlines from multiple RSS feeds (e.g., CISA, BleepingComputer, Krebs, SecurityWeek, Ars Technica, TechCrunch, Hacker News). - De-duplicates stories, keeps only the last 24 hours, and limits to a manageable number. - Uses OpenAI to write a concise brief with sections and "Why it matters." - Sends a clean HTML email via Gmail. Category: Security / News\ Time to set up: 10--15 minutes\ Difficulty: Beginner--Intermediate\ Cost: Mostly free (OpenAI tokens + Gmail) What you'll need -------------------- - n8n (recent version) - OpenAI credentials - Gmail (or SMTP) credentials - A few free RSS feed URLs (swap in/out as you like) Set up steps ---------------- - Trigger -- Add a Cron to run daily (pick your time and timezone). - Fetch -- Add one RSS Read node per source and connect all to a Merge (append). - De-duplicate (this run) -- Add Remove Duplicates and compare on a stable key (prefer the article URL). - Freshness -- Add an IF to pass only items published in the last 24 hours. - Limit -- Add Limit to cap the total items (e.g., 25). - Summarize -- Add OpenAI → Message a model to produce a JSON brief with subject + HTML body. - Email -- Add Gmail → Send to deliver the brief to your inbox. Tips & troubleshooting -------------------------- - If everything gets discarded at de-dup e while testing, switch to "within current input" or reset the node's stored values. - If no items pass the IF, widen the date window temporarily (some feeds publish late). - If the email arrives blank, ensure Gmail email type is set to HTML and the subject/body fields map to the model's output. Sources you can start with (swap freely) -------------------------------------------- CISA, BleepingComputer, KrebsOnSecurity, SecurityWeek, Ars Technica (Security), TechCrunch (Security), Hacker News (front page).
