# AI Conversation Memory & Knowledge Base Guide

## 🧠 **Conversation Memory Implementation**

### Overview
The university portal now features **intelligent conversation memory** that allows the AI to remember previous interactions and provide contextually relevant responses. This creates a more natural, human-like conversation experience.

### How It Works

#### 1. **Conversation Session Management**
```typescript
// Each chat session gets a unique conversation ID
const conversationId = `conv_${Date.now()}_${Math.random().toString(36).substr(2, 9)}`;
```

#### 2. **Message History Storage**
- **Database Storage**: All messages are stored in the `ChatMessage` table
- **Context Preservation**: Up to 10 previous messages are included in AI context
- **User Context**: User role and profile information is preserved

#### 3. **Memory Features**
- ✅ **Session Continuity**: AI remembers the entire conversation
- ✅ **Context Awareness**: References previous questions and answers
- ✅ **Personalization**: Adapts responses based on user role and history
- ✅ **Multi-University**: Each university has isolated conversation history

### Database Schema

```sql
-- Chat Message for conversation memory
model ChatMessage {
  id             String   @id @default(uuid())
  conversationId String
  role           String   // 'user' | 'assistant' | 'system'
  content        String
  universitySlug String?
  userContext    String?  // JSON string of user context
  createdAt      DateTime @default(now())

  // Relationships
  session ChatSession @relation(fields: [conversationId], references: [id], onDelete: Cascade)
}
```

      "name": "John Doe",
      "year": 2,
      "faculty": "Engineering"
    }
  }
}
```

#### **Knowledge Base Management**
```http
# Get all knowledge base items
GET /api/knowledge-base

# Create new item
POST /api/knowledge-base
{
  "category": "Admissions",
  "question": "What are the requirements?",
  "answer": "Detailed answer...",
  "priority": 2,
  "isActive": true
}

# Update item
PUT /api/knowledge-base/{id}
{
  "question": "Updated question",
  "answer": "Updated answer"
}

# Toggle active status
PATCH /api/knowledge-base/{id}
{
  "isActive": false
}

# Delete item
DELETE /api/knowledge-base/{id}
```

### AI Context Building

#### **System Prompt Enhancement**
```typescript
const systemPrompt = `You are a helpful AI assistant for a university portal.

${personalizedContext}
${universityContext}

Remember to maintain context from the conversation history and provide personalized responses based on the user's role and profile.`;
```

#### **Message History Integration**
```typescript
const messages: ChatMessage[] = [
  { role: 'system', content: systemPrompt },
  ...conversationHistory,  // Previous 10 messages
  { role: 'user', content: message }
];
```
