Deep research agent - automated research & Notion report builder

# Deep Research Agent - Automated Research & Notion Report Builder

This n8n workflow automates the process of conducting deep research on a given topic and compiling the findings into a structured report within Notion. It leverages AI agents to perform the research, summarize information, and generate a comprehensive output, streamlining the knowledge acquisition and documentation process.

## What it does

1.  **Receives Research Request**: Listens for an incoming webhook trigger, which is expected to contain the research topic.
2.  **Initial Data Preparation**: Processes the incoming request to set up the necessary fields for the AI agent.
3.  **Initiates AI Research Agent**: Calls an AI Agent (likely powered by LangChain and an LLM like OpenAI or Google Gemini) to perform deep research on the specified topic.
4.  **Extracts Structured Output**: Utilizes a Structured Output Parser to extract key information from the AI agent's response in a defined format.
5.  **Generates Markdown Report**: Converts the extracted research findings into a well-formatted Markdown report.
6.  **Creates Notion Page**: Creates a new page in Notion, using the generated Markdown content as the body of the report.
7.  **Responds to Webhook**: Sends a response back to the triggering webhook, indicating the completion of the research and Notion page creation.

## Prerequisites/Requirements

To use this workflow, you will need:

*   **n8n Instance**: A running n8n instance.
*   **Webhook Trigger**: An external system or application to send research requests via a webhook.
*   **AI Agent Credentials**:
    *   **OpenAI API Key** OR
    *   **Google Gemini API Key** OR
    *   **OpenRouter API Key** (depending on which LLM is configured in the "AI Agent" and "Chat Model" nodes).
*   **Notion Integration**: A Notion integration with appropriate permissions to create pages in your desired database or workspace. You will need to configure a Notion credential in n8n.

## Setup/Usage

1.  **Import the Workflow**:
    *   Download the provided JSON file.
    *   In your n8n instance, go to "Workflows" and click "New".
    *   Click the three dots menu (`...`) and select "Import from JSON".
    *   Paste the workflow JSON or upload the file.
2.  **Configure Credentials**:
    *   Locate the "AI Agent" node and its associated "Chat Model" node (e.g., "OpenAI", "Google Gemini Chat Model", or "OpenRouter Chat Model"). Configure the necessary API key credentials for your chosen Large Language Model.
    *   Locate the "Notion" node. Configure your Notion API key credential, ensuring it has access to the Notion database or page where you want to create reports.
3.  **Activate the Webhook**:
    *   The "Webhook" node is the trigger for this workflow. Once the workflow is active, it will provide a unique URL. Copy this URL.
4.  **Send Research Requests**:
    *   Send POST requests to the copied Webhook URL with a JSON body containing the research topic. For example:
        ```json
        {
          "topic": "The impact of AI on customer service in 2024"
        }
        ```
5.  **Run the Workflow**:
    *   Ensure the workflow is activated in n8n.
    *   Upon receiving a webhook request, the workflow will execute, conduct the research, and create a Notion page.
