📅 AGENT OF THE WEEK

Agent Overview: This guide walks you through building a research agent that tracks only relevant AI agent news everyday. Using n8n and Perplexity, you’ll automate daily updates so you always know what’s actually new in the agent world.

Step-by-Step:

  1. Open up n8n and create a new workflow (free account lasts 2 weeks)

  2. Drop in your preferred LLM model (GPT-4, Claude, etc.) — I used GPT 4.1

  3. Add in the Perplexity node to your agent and choose the “Sonar-pro” model for live, complex internet searches

  4. Set the rules: Use a clear prompt (like ours) that only allows gathers news on your topic, skipping all generic or aggregator posts

  5. Define your output: Each result gives you headline, source, link, date, category, and a one liner summary that’s perfect for reading each morning

Bonus: We’ve put together a detailed video walkthrough and the exact n8n workflow. Access both in our Building AI Agents Community here!
