title: "Customer Support Bot"
description: "Build an intelligent support system that remembers customer history and provides personalized help"
---

Create a customer support system that remembers every interaction, tracks issues across conversations, and provides personalized support based on customer history and preferences.

## What You'll Build

A customer support bot that:
- **Remembers customer history** across all conversations and channels
- **Tracks ongoing issues** and follows up automatically
- **Provides personalized responses** based on customer tier and preferences
- **Escalates complex issues** to human agents with full context
- **Learns from resolutions** to improve future responses

## Prerequisites

- Node.js 18+ or Python 3.8+
- Supermemory API key
- OpenAI API key
- Customer database or CRM integration
- Basic understanding of customer support workflows

## Implementation

SUPPORT GUIDELINES:
1. **Personalization**: Address the customer by name and reference their tier/history when relevant
2. **Context Awareness**: Use previous interactions to inform your response
3. **Tier-Specific Service**:
   - Free: Standard support, guide to self-service resources
   - Pro: Priority support, detailed explanations, proactive suggestions
   - Enterprise: White-glove service, immediate escalation path, dedicated attention

4. **Issue Tracking**: If this is a new issue, categorize it (billing, technical, account, product)
5. **Escalation**: ${needsEscalation ? 'This interaction may need human agent escalation - provide helpful response but prepare escalation summary' : 'Handle directly unless customer specifically requests human agent'}

RESPONSE STYLE:
- Professional but friendly
- Reference specific details from customer history when relevant
- Provide actionable next steps
- Include relevant links or resources for their tier level

If you cannot resolve the issue completely, prepare a clear summary for escalation to human agents.`

SUPPORT GUIDELINES:
1. **Personalization**: Address the customer by name and reference their tier/history when relevant
2. **Context Awareness**: Use previous interactions to inform your response
3. **Tier-Specific Service**:
   - Free: Standard support, guide to self-service resources
   - Pro: Priority support, detailed explanations, proactive suggestions
   - Enterprise: White-glove service, immediate escalation path, dedicated attention

4. **Issue Tracking**: If this is a new issue, categorize it (billing, technical, account, product)
5. **Escalation**: {'This interaction may need human agent escalation - provide helpful response but prepare escalation summary' if needs_escalation else 'Handle directly unless customer specifically requests human agent'}

RESPONSE STYLE:
- Professional but friendly
- Reference specific details from customer history when relevant
- Provide actionable next steps
- Include relevant links or resources for their tier level

If you cannot resolve the issue completely, prepare a clear summary for escalation to human agents."""

   - Enterprise: White-glove service, escalation readiness

2. **Test Memory & Context**:
   - Ask about a previous issue
   - Reference customer preferences
   - Follow up on unresolved tickets

3. **Test Escalation Triggers**:
   - Use keywords like "angry", "manager", "refund"
   - Test enterprise customer automatic escalation
