AI-Powered Reddit Engagement & Moderation with Ollama
detail.loadingPreview
Automate your Reddit engagement and content moderation with this powerful n8n workflow. It leverages a local AI model (Ollama) to analyze new Reddit posts for relevance, logs insights to Google Sheets, and automatically responds to relevant discussions.
About This Workflow
This n8n workflow provides a robust solution for intelligent Reddit monitoring and interaction. Triggered manually, it fetches recent posts from specified subreddits and intelligently filters out duplicates by comparing them against a log in Google Sheets. The core of the workflow is its integration with Ollama via Langchain, enabling a local AI to perform advanced relevance analysis on each new post. Based on the AI's decision, the workflow either logs the post as irrelevant, or marks it as relevant, records it in Google Sheets, and then posts a pre-defined comment directly back to the Reddit thread, ensuring timely and context-aware engagement.
Key Features
- AI-Driven Relevance Analysis: Utilizes a local Ollama AI model via Langchain to intelligently assess the relevance of Reddit posts.
- Automated Duplicate Filtering: Prevents repetitive processing by cross-referencing new posts against a Google Sheet log of previously handled content.
- Conditional Engagement: Automatically posts comments on Reddit only for posts identified as highly relevant by the AI.
- Comprehensive Logging: Maintains a detailed record of all processed posts, both relevant and irrelevant, in Google Sheets for auditing and insights.
- Seamless Reddit Integration: Connects directly to Reddit to fetch posts and publish automated comments.
