Automated research report generation with AI, Wiki, Search & Gmail/Telegram

Automated Research Report Generation with OpenAI, Wikipedia, Google Search, Gmail/Telegram and PDF Output

Description

What Problem Does This Solve? 🛠️

This workflow automates the process of generating professional research reports for researchers, students, and professionals. It eliminates manual research and report formatting by aggregating data, generating content with AI, and delivering the report as a PDF via Gmail or Telegram. Target audience: Researchers, students, educators, and professionals needing quick, formatted research reports.

What Does It Do? 🌟

• Aggregates research data from Wikipedia, Google Search, and SerpApi.
• Refines user queries and generates structured content using OpenAI.
• Converts the content into a professional HTML report, then to PDF.
• Sends the PDF report via Gmail or Telegram.

Key Features 📋

• Real-time data aggregation from multiple sources.
• AI-driven content generation with OpenAI.
• Automated HTML-to-PDF conversion for professional reports.
• Flexible delivery via Gmail or Telegram.
• Error handling for robust execution.

Setup Instructions

Prerequisites ⚙️

• n8n Instance: Self-hosted or cloud n8n instance.
• API Credentials:
  • OpenAI API: API key with GPT model access, stored in n8n credentials.
  • SerpApi (Google Search): API key from SerpApi, stored in n8n credentials (do not hardcode in nodes).
  • Gmail API: Credentials from Google Cloud Console with Gmail scope.
  • Telegram API: Bot token from BotFather on Telegram.

Installation Steps 📦

1. Import the Workflow:
   • Copy the workflow JSON from the "Template Code" section below.
   • Import it into n8n via "Import from File" or "Import from URL".
2. Configure Credentials:
   • Add API credentials in n8n’s Credentials section for OpenAI, SerpApi, Gmail, and Telegram.
   • Assign credentials to respective nodes. For example:
     • In the SerpApi Google Search node, use n8n credentials for SerpApi: api_key={{ $credentials.SerpApiKey }}.
     • In the Send Research PDF on Gmail node, use Gmail credentials.
     • In the Send PDF to Telegram node, use Telegram bot credentials.
3. Set Up Nodes:
   • OpenAI Nodes (Research AI Agent, OpenAI Chat Model, OpenAI Chat Middle Memory): Update the model (e.g., gpt-4o) and prompt as needed.
   • Input Validation (Input Validation node): Ensure your input query format matches the expected structure (e.g., topic: "AI ethics").
   • Delivery Options (Send Research PDF on Gmail, Send PDF to Telegram): Configure recipient email or Telegram chat ID.
4. Test the Workflow:
   • Run the workflow by clicking the "Test Workflow" node.
   • Verify that the research report PDF is generated and sent via Gmail or Telegram.
