Monitor brand reputation for negative PR on Reddit with Gemini + LangChain + Sheets

🎥 Watch the Full Execution on YouTube Workflow Description (in-depth): This workflow automates the entire process of monitoring online reputation by scanning Reddit posts for negative sentiment about your company, filtering only the relevant criticism, and logging it directly into Google Sheets for easy tracking. 🔑 Key Features: Automated Triggering: Runs on a schedule so you never miss new discussions about your brand. Smart Data Fetching: Uses Reddit API to pull the latest posts matching your chosen keywords (e.g., “Notion”). Post Processing: Breaks down bulk Reddit responses into individual posts for analysis. AI-Powered Filtering: A custom-built AI agent reviews the content and extracts only genuine negative PR (complaints, bad experiences, harmful mentions). Neutral or positive posts are ignored. Structured Parsing: AI responses are enforced into a clean JSON schema (ID, Title, URL, NegativeContent).... ensuring compatibility with downstream nodes. Noise Reduction: A code node ensures only posts with meaningful content are passed forward. Centralized Logging: Captures critical information (post title, negative excerpt, URL, ID) into Google Sheets.... giving teams a live dashboard of issues to address. Customizable & Scalable: Swap out “Notion” for your own brand, or expand to other platforms.... the flow adapts without extra overhead. 🚀 Why This Matters: In 2025, a single Reddit thread can shape brand reputation overnight. Manually monitoring is inefficient, and traditional social listening tools generate too much noise. This workflow gives you a lean, automated, AI-powered system to stay ahead of potential PR risks. 🛠️ Tech Stack: n8n for automation Reddit API for data fetching LangChain AI Agent + Google Vertex Model for sentiment & context analysis Google Sheets for reporting & tracking
