Build an Interactive AI Agent with Chat Interface and Tools
Overview
This workflow enables you to create a fully functional AI Agent with a live chat interface, memory, and access to multiple real-time tools. Unlike a basic chatbot, this agent can perform actions like calculations, content retrieval, and information lookup—giving users a rich, interactive experience. Perfect for teams exploring AI-powered assistants, internal tools, or customer-facing support agents.
How It Works
-
Chat Interface (Chat Trigger):
Users interact with a styled, public-facing chat window that serves as the front-end for the AI Agent. -
AI Agent Node (The Brain):
This node acts as the core processor. It analyzes the user's message, interprets the intent, and determines which connected tool to trigger. The agent's behavior and tone are guided by a detailed system prompt. -
Tool Nodes (Superpowers):
Each tool gives the agent a specific ability. Included tools:
-> Fetch a random joke
-> Search and summarize Wikipedia articles
-> Calculate future dates
-> Generate secure passwords
-> Estimate monthly loan payments
-> Get the latest articles from the n8n blog -
Memory Node (Context Awareness)
Stores recent conversation history so the agent can respond with context and continuity across messages. -
Memory Node (Context Awareness)
Stores recent conversation history so the agent can respond with context and continuity across messages. -
Response Generation
After using a tool, the agent composes a helpful reply and sends it back through the chat interface.
Setup Instructions
Estimated Setup Time: 3–5 minutes
-
Step 1: Configure AI Credentials
Use either OpenAI (ChatGPT) or Google Gemini by enabling the corresponding node in your workflow. Only one LLM node should be active. -
Step 2: Customize Tools
Modify existing tool nodes or add your own to tailor the agent’s capabilities. - Step 3: Launch and Test
Activate the workflow
Copy the public URL from the Chat Interface node
Start chatting with your AI Agent
Example prompts to try:
“Tell me a joke.”

“What’s the monthly payment for a $300,000 loan over 30 years at 5%?”
“What are the latest blog posts on n8n.io?”
