Automate Content Research with Reddit Scraping, AI Analysis, and Google Sheets

This n8n workflow automates the process of gathering content ideas from Reddit, analyzing them with AI, and storing the results in Google Sheets for further use. It simplifies content research by automatically identifying trending topics and extracting key insights.

What it does

This workflow performs the following steps:

  1. Triggers on a Schedule: The workflow starts automatically at predefined intervals (e.g., daily, weekly).
  2. Scrapes Reddit: It connects to Reddit to fetch posts from specified subreddits or based on certain keywords.
  3. Analyzes with AI: The retrieved Reddit posts are then sent to an AI agent (powered by OpenAI) for analysis. The AI agent extracts relevant information, such as content themes, sentiment, or key takeaways.
  4. Parses AI Output: A structured output parser ensures that the AI's response is formatted consistently, making it easy to process.
  5. Edits Fields: Data is transformed and cleaned to prepare it for storage.
  6. Merges Data: Combines the original Reddit data with the AI-analyzed insights.
  7. Stores in Google Sheets: The final, enriched data is then appended to a Google Sheet, creating a centralized repository for content ideas.

Prerequisites/Requirements

To use this workflow, you will need:

  • n8n Instance: A running n8n instance (cloud or self-hosted).
  • Reddit Account & API Credentials: To scrape Reddit posts.
  • OpenAI API Key: For the AI Agent and Chat Model to analyze content.
  • Google Account: With access to Google Sheets to store the research data.

Setup/Usage

  1. Import the Workflow: Download the provided JSON and import it into your n8n instance.
  2. Configure Credentials:
    • Reddit: Set up your Reddit OAuth2 or API credentials in n8n.
    • OpenAI: Add your OpenAI API Key as a credential.
    • Google Sheets: Authenticate your Google account to allow n8n to access your Google Sheets.
  3. Customize Nodes:
    • Schedule Trigger: Adjust the schedule to your preferred frequency for running the research.
    • Reddit Node: Configure the subreddits, keywords, or other filters for the posts you want to scrape.
    • AI Agent Node: Refine the prompt for the AI agent to guide its analysis (e.g., "Summarize the main content idea and identify potential angles for a blog post").
    • Google Sheets Node: Specify the Spreadsheet ID and Sheet Name where you want to store the data. Ensure the sheet has appropriate headers matching the data output.
  4. Activate the Workflow: Once configured, activate the workflow. It will now run automatically based on your defined schedule.

The Telegram bot (created with BotFather) connects directly to your n8n instance. Demo Guidance The RAG agent and instructor guide the user step-by-step through the demo. Instructions and responses are dynamically generated based on user input. Workflow Execution When the user triggers an action (e.g., testing the email demo), n8n runs the workflow. The workflow collects website data using Crawl4AI or standard HTTP requests. Email Demo The system personalizes and sends a demo email through SparkPost, showing the automation’s capability. Logging and Control Each user interaction is logged in your database using their name and id. The workflow checks limits to prevent misuse or spam. Error Handling If a low-CPU scraping method fails, the workflow automatically escalates to a higher-CPU method. ⚙️ Requirements Before setting up, make sure you have the following: n8n — Automation platform to run the workflow Docker — Required to run Crawl4AI Crawl4AI — For intelligent website crawling Telegram Account — To create your Telegram bot via BotFather SparkPost Account — To send personalized demo emails A database (e.g., PostgreSQL, MySQL, or SQLite) — To store log data such as user name and ID 🚀 Features Telegram interface using the BotFather API Instructor and RAG agent to guide prospects through the demo Flow generation limits per user ID to prevent abuse Low-cost yet powerful web scraping, escalating from low- to high-CPU flows if earlier ones fail --- 💡 Development Ideas Replace the RAG logic with your own query-answering and guidance method Remove the flow limit if you’re confident the demo can’t be misused Swap the personalized email demo with any other workflow you want to showcase --- 🧠 Technical Notes Telegram bot created with BotFather Website crawl process: Extract sub-links via /sitemap.xml, sitemap_index.xml, or standard HTTP requests Fall back to Crawl4AI if normal requests fail Fetch sub-link content via HTTPS or Crawl4AI as backup SparkPost used for sending demo emails --- ⚙️ Setup Instructions Create a Telegram Bot Use BotFather on Telegram to create your bot and get the API token.
