Overview

Unlock Instant Answers with this AI Agent

This n8n workflow transforms your Notion workspace into an intelligent, conversational knowledge base. It acts as an AI Agent, powered by OpenAI's GPT-4o and Langchain, allowing you to chat directly with your Notion data. Ask questions in natural language, and the agent will search your specified Notion database, retrieve relevant page content, and provide concise answers or summaries. It even remembers the context of your conversation for follow-up questions.

  • AI-Powered Search: Leverages OpenAI (GPT-4o) to understand queries and intelligently search your Notion database using keywords or tags.
  • Deep Content Retrieval: Can fetch and process the content within specific Notion pages to provide comprehensive answers.
  • Dynamic Tag Awareness: Automatically pulls the latest tag options from your Notion database to refine search capabilities.
  • Contextual Memory: Remembers previous turns in the conversation for more natural and relevant follow-ups.

  • Notion API credentials (Internal Integration Token).
  • A Notion database you want to query, shared with your Notion integration.

Setup Instructions

  1. Download the n8n workflow JSON file.
  2. Import the workflow into your n8n instance.
  3. Configure your Notion API credentials in the 'Get database details', 'Search notion database', and 'Search inside database record' nodes.
  4. Configure your OpenAI API Key in the 'OpenAI Chat Model' node. (The template is pre-configured for GPT-4o but can be adapted).
  5. In the 'Get database details' node, select your target Notion Database ID from the dropdown list. Ensure this database is shared with your Notion integration.
  6. Review the system prompt in the 'AI Agent' node (under 'Options') and customize it to refine the agent's behavior and knowledge about your specific Notion database structure if needed.
