How it works

This template launches your very first AI Agent —an AI-powered chatbot that can do more than just talk— it can take action using tools.

Think of an AI Agent as a smart assistant, and the tools are the apps on its phone. By connecting it to other nodes, you give your agent the ability to interact with real-world data and services, like checking the weather, fetching news, or even sending emails on your behalf.

This workflow is designed to be the perfect starting point:

  • The Chat Interface: A Chat Trigger node provides a simple, clean interface for you to talk to your agent.
  • The Brains: The AI Agent node receives your messages, intelligently decides which tool to use (if any), and formulates a helpful response. Its personality and instructions are fully customizable in the "System Message".
  • The Language Model: It uses Google Gemini to power its reasoning and conversation skills.
  • The Tools: It comes pre-equipped with two tools to demonstrate its capabilities:
    1. Get Weather: Fetches real-time weather forecasts.
    2. Get News: Reads any RSS feed to get the latest headlines.
  • The Memory: A Conversation Memory node allows the agent to remember the last few messages, enabling natural, follow-up conversations.

Set up steps

Setup time: ~2 minutes

You only need one thing to get started: a free Google AI API key.

  1. Get Your Google AI API Key:

  2. Add Your Credential in n8n:

    • On the workflow canvas, go to the Connect your model (Google Gemini) node.
    • Click the Credential dropdown and select + Create New Credential.
    • Paste your API key into the API Key field and click Save.

  3. Start Chatting!

    • Go to the Example Chat node.
    • Click the "Open Chat" button in its parameter panel.
    • Try asking it one of the example questions, like: "What's the weather in Paris?" or "Get me the latest tech news."

That's it! You now have a fully functional AI Agent. Try adding more tools (like Gmail or Google Calendar) to make it even more powerful.

AI Agent with Google Gemini Chat and Simple Memory

This n8n workflow demonstrates how to build a basic AI agent capable of engaging in conversational interactions using Google Gemini and maintaining a simple memory of the conversation. It provides a foundational setup for creating interactive AI assistants.

What it does

  1. Listens for Chat Messages: The workflow is triggered whenever a new chat message is received, acting as the input for the AI agent.
  2. Initializes Simple Memory: A Simple Memory component is used to store and retrieve past conversational turns, allowing the AI agent to maintain context throughout the interaction.
  3. Utilizes Google Gemini Chat Model: The Google Gemini Chat Model is configured as the underlying Large Language Model (LLM) for the AI agent, providing its conversational capabilities.
  4. Processes with AI Agent: The AI Agent node orchestrates the interaction, combining the input chat message, the conversational memory, and the Gemini chat model to generate a coherent and contextually relevant response.

Prerequisites/Requirements

  • n8n Instance: An active n8n instance to import and run the workflow.
  • Google Gemini API Key: You will need access to the Google Gemini API to use the Google Gemini Chat Model node. This typically involves setting up a Google Cloud project and enabling the Gemini API.
  • LangChain Nodes: Ensure you have the @n8n/n8n-nodes-langchain package installed in your n8n instance, as this workflow heavily relies on its nodes.

Setup/Usage

  1. Import the Workflow:
    • Download the provided JSON file for this workflow.
    • In your n8n instance, go to "Workflows" and click "New".
    • Click the "Import from JSON" button and paste the workflow JSON or upload the file.
  2. Configure Credentials:
    • Locate the Google Gemini Chat Model node.
    • You will need to configure the credentials for your Google Gemini API key within this node.
  3. Activate the Workflow:
    • Once configured, activate the workflow by toggling the "Active" switch in the top right corner of the workflow editor.
  4. Interact with the Agent:
    • The When chat message received trigger node will be listening for incoming messages. Depending on how this trigger is exposed (e.g., via a webhook or integration), you can send messages to it to start interacting with your AI agent.

Automated UGC video generator with Gemini images and SORA 2

This workflow automates the creation of user-generated-content-style product videos by combining Gemini's image generation with OpenAI's SORA 2 video generation. It accepts webhook requests with product descriptions, generates images and videos, stores them in Google Drive, and logs all outputs to Google Sheets for easy tracking. Main Use Cases Automate product video creation for e-commerce catalogs and social media. Generate UGC-style content at scale without manual design work. Create engaging video content from simple text prompts for marketing campaigns. Build a centralized library of product videos with automated tracking and storage. How it works The workflow operates as a webhook-triggered process, organized into these stages: Webhook Trigger & Input Accepts POST requests to the /create-ugc-video endpoint. Required payload includes: product prompt, video prompt, Gemini API key, and OpenAI API key. Image Generation (Gemini) Sends the product prompt to Google's Gemini 2.5 Flash Image model. Generates a product image based on the description provided. Data Extraction Code node extracts the base64 image data from Gemini's response. Preserves all prompts and API keys for subsequent steps. Video Generation (SORA 2) Sends the video prompt to OpenAI's SORA 2 API. Initiates video generation with specifications: 720x1280 resolution, 8 seconds duration. Returns a video generation job ID for polling. Video Status Polling Continuously checks video generation status via OpenAI API. If status is "completed": proceeds to download. If status is still processing: waits 1 minute and retries (polling loop). Video Download & Storage Downloads the completed video file from OpenAI. Uploads the MP4 file to Google Drive (root folder). Generates a shareable Google Drive link. Logging to Google Sheets Records all generation details in a tracking spreadsheet: Product description Video URL (Google Drive link) Generation status Timestamp Summary Flow: Webhook Request → Generate Product Image (Gemini) → Extract Image Data → Generate Video (SORA 2) → Poll Status → If Complete: Download Video → Upload to Google Drive → Log to Google Sheets → Return Response If Not Complete: Wait 1 Minute → Poll Status Again Benefits: Fully automated video creation pipeline from text to finished product. Scalable solution for generating multiple product videos on demand. Combines cutting-edge AI models (Gemini + SORA 2) for high-quality output. Centralized storage in Google Drive with automatic logging in Google Sheets. Flexible webhook interface allows integration with any application or service. Retry mechanism ensures videos are captured even with longer processing times. --- Created by Daniel Shashko
