This n8n template automates complaint mining from unstructured text sources and turns raw user feedback into clear, actionable insights.
It uses AI to identify recurring complaints, pain points, and themes, helping teams understand what users are unhappy about and why.

Who’s it for

• Product managers identifying recurring user pain points
• Customer support and success teams
• Founders validating product-market fit issues
• UX researchers analyzing qualitative feedback

How it works / What it does

1. Trigger

   • The workflow starts with a manual trigger, form submission, or imported text source containing user complaints.

2. Data Preparation

   • Raw complaint text is cleaned, normalized, and split into individual complaint entries.
   • Ensures consistent input for AI processing.

3. AI Complaint Analysis

   • An AI model analyzes each complaint to identify:
     • Core issue
     • Complaint category
     • Emotional tone
     • Severity or urgency

4. Pattern Detection

   • Complaints are grouped by similarity to uncover recurring issues and themes.
   • Highlights the most frequent and impactful problems.

5. Insight Extraction

   • AI summarizes key insights such as:
     • Top recurring complaints
     • Root causes
     • Suggested improvement areas

6. Structured Output

   • Results are converted into structured data fields.
   • Ready to be stored, visualized, or shared with stakeholders.

7. Storage & Reporting

   • Extracted complaints and insights are saved to a table or sheet for easy review and analysis.

This workflow transforms unstructured complaint data into a clear feedback loop you can act on.
