Reddit Q&A Chatbot with GPT-4o & Reddit API

This n8n workflow creates a powerful Q&A chatbot for Reddit content, integrating the Reddit API to fetch posts from specified subreddits and GPT-4o for processing and responding to user queries. When a chat message is received, the workflow retrieves relevant posts (e.g., from r/n8n), feeds them into an OpenAI Agent, and generates concise, context-aware answers with citations to original Reddit sources.

Key features include easy credential setup for OpenAI and Reddit OAuth2, customizable subreddit targeting, and seamless chat interface. It handles summarization, question-answering, and context retention, making Reddit data instantly accessible via natural language.

Benefits: Saves hours of manual scrolling through Reddit threads, provides AI-powered insights for faster research, reduces misinformation by grounding responses in real posts, and scales for multiple subreddits. Ideal for businesses monitoring communities or individuals exploring topics.

Use cases: Market researchers analyzing subreddit trends, content creators sourcing ideas from discussions, support teams gauging user sentiment, educators building topic explorers, or developers prototyping AI chat tools. Customizable for filtering posts by keywords, dates, or scores.
