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

// 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

-- 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)
}

• Programs: Course information, requirements, career paths
• Campus Life: Facilities, events, student services
• Financial Aid: Scholarships, fees, payment options
• Research: Research opportunities, facilities, publications

3. Priority System

• High Priority: Critical information (admissions, deadlines)
• Medium Priority: Important information (programs, services)
• Low Priority: General information (campus life, events)

AI Context Building

System Prompt Enhancement

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

const messages: ChatMessage[] = [
  { role: 'system', content: systemPrompt },
  ...conversationHistory,  // Previous 10 messages
  { role: 'user', content: message }
];
