Monitor Reddit for Negative Brand PR with AI & Google Sheets

This n8n workflow monitors your brand's online reputation by automatically fetching recent Reddit posts matching keywords like your company name (e.g., 'Notion'). It uses the Reddit API on a schedule to pull data, processes bulk responses into individual posts, and employs an AI agent powered by Gemini and LangChain to analyze sentiment. Only genuine negative PR—such as complaints or harmful mentions—is extracted, ignoring neutral or positive content, with results structured into clean JSON (ID, Title, URL, NegativeContent).

A code node further reduces noise by filtering posts with meaningful content, ensuring efficiency. The workflow then logs key details (title, negative excerpt, URL, post ID) directly into Google Sheets, creating a live dashboard for teams to monitor and respond to issues promptly.

Benefits include time-saving automation over manual monitoring, reduced noise from traditional tools, and scalability—easily swap brands or expand to other platforms. Ideal for marketing teams, PR managers, or any business protecting reputation in 2025's fast-moving social landscape, preventing small threads from escalating into crises.
