Workflow Logic

1. Schedule Trigger

Kicks off the automation every 4 hours to avoid rate limits.

2. Define Subreddits

Iterates through your custom list (e.g., r/SaaS, r/Entrepreneur).

3. Get Posts & Clean Data

Fetches the raw data and extracts Title, Content, URL, and Upvotes.

4. AI Classifier (The Brain)

GPT-4o-mini analyzes the context. It routes the data into 3 branches based on intent.

5. Logging & Alerting

Qualified leads are saved to Sheets. High-priority alerts go to Slack.

Setup Steps

Step 1: Import Workflow

Download the JSON file below and import it into your n8n instance.

Download JSON

Step 2: Customize Subreddits

Locate the node named Edit Fields1. Replace the JSON array with your niche targets.

JSON Configuration 
{
 "subreddit": [
 "Entrepreneur",
 "SaaS",
 "smallbusiness",
 "Zapier",
 "nocode"
 ]
}

Step 3: Update AI Prompts (Optional)

The system message in the OpenAI node controls the quality. Here is the logic for "Automation Requests":

System Prompt 
Analyze reddit post from user requesting an AI automation system.
- Summarize the exact system they want built
- Assign relevancy score (0.05-0.95)
- Assign detail score (0.9+ = enough info to recreate in n8n)

Optimization Tips

Best Practices

Schedule Frequency

Keep it at 4 hours. If you go below 2 hours, Reddit might rate-limit your IP address.

Volume Control

Increase "Limit" in the Reddit node from 20 to 50 if you are targeting very active subreddits like r/ChatGPT.
