}
```

### **API Endpoints**
```http
# Chat with Memory
POST /api/chat/ollama
GET /api/chat/ollama

# Knowledge Base Management
GET /api/knowledge-base
POST /api/knowledge-base

PATCH /api/knowledge-base/{id}
DELETE /api/knowledge-base/{id}
```

### **Enhanced AI Context**
```typescript
const systemPrompt = `You are a helpful AI assistant for a university portal.

${personalizedContext}        // User role and profile
${universityContext}          // University-specific knowledge base
${conversationHistory}        // Previous 10 messages

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