AI PR AGENT N8N WORKFLOW

Node by Node Walkthrough

1. Schedule Trigger – kicks off my automation at regular intervals so I don’t need to manually run anything.
2. HTTP Request (Reddit Search) – fetches the freshest Reddit posts about Notion straight from the source.
3. Set Node – extracts only the key metadata from the Reddit API response.... keeps the workflow clean and lightweight.
4. SplitOut Node – breaks the bulk posts into individual items so each one can be analyzed separately.
5. AI Agent – my custom AI that checks each post and decides if it’s genuinely negative PR or just noise.... it only keeps the real criticism.
6. Code Node – filters out any empty or irrelevant results so the sheet doesn’t get cluttered.
7. Google Sheets Node – neatly logs the negative posts (title, content, link, and ID) into my sheet.... giving me a live dashboard of complaints.
8. Structured Output Parser + Vertex Model – ensures the AI output comes back in the exact format I want.... no messy responses, just structured data ready to use.
