n8n Social Listening Chat Agent w/ OpenAI & API Direct

Turn questions into cited social & web research—automatically

This n8n workflow builds a chat-based social listening research assistant that uses an OpenAI chat model plus API Direct search tools to find fresh answers from Twitter/X, Reddit, TikTok, and Google web search, then returns a consolidated, sourced summary.

What this workflow does

• Receives your question through an n8n Chat trigger.
• Passes the question to an OpenAI-powered agent (via n8n LangChain agent tooling) with instructions to use external search when needed and cite sources.
• The agent generates search queries, then fetches relevant results from:
  • Twitter/X using an API Direct tool
  • Reddit using an API Direct tool
  • TikTok using an API Direct tool
  • Google web search using an API Direct tool
• Returns a single response that references the links used and notes which platform each finding came from.

Use cases

• Get rapid, cited summaries of brand or product mentions across Twitter/X, Reddit, and TikTok.
• Research competitors by asking targeted questions and receiving platform-specific sources.
• Monitor emerging topics using fresh Google web search results alongside social sources.
• Support SaaS operations with an always-available “ask and summarize” research chat in n8n.
