description: "Build an AI assistant that remembers user preferences, habits, and context across conversations"
---

Build a personal AI assistant that learns and remembers everything about the user - their preferences, habits, work context, and conversation history. This recipe shows how to create a truly personalized AI experience using Supermemory's memory tools.

## What You'll Build

A personal AI assistant that:
- **Remembers user preferences** (dietary restrictions, work schedule, communication style)
- **Learns from conversations** and improves responses over time
- **Maintains context** across multiple chat sessions
- **Provides personalized recommendations** based on user history
- **Handles multiple conversation topics** while maintaining context

## Prerequisites

- Node.js 18+ or Python 3.8+
- Supermemory API key
- OpenAI or Anthropic API key
- Basic understanding of chat applications

## Implementation

### Step 1: Project Setup

<Tabs>
  <Tab title="Next.js (TypeScript)">
    ```bash
    npx create-next-app@latest personal-ai --typescript --tailwind --eslint
    cd personal-ai
    npm install @supermemory/tools ai openai
    ```

    Create your environment variables:
    ```bash .env.local
    SUPERMEMORY_API_KEY=your_supermemory_key
    OPENAI_API_KEY=your_openai_key
    ```
  </Tab>

  <Tab title="Python">
    ```bash
    mkdir personal-ai && cd personal-ai
    python -m venv venv
    source venv/bin/activate  # On Windows: venv\Scripts\activate
    pip install supermemory openai fastapi uvicorn python-multipart
    ```

    Create your environment variables:
    ```bash .env
    SUPERMEMORY_API_KEY=your_supermemory_key
    OPENAI_API_KEY=your_openai_key
    ```
  </Tab>
</Tabs>

### Step 2: Core Assistant Logic

        system: `You are a highly personalized AI assistant. Your primary goal is to learn about the user and provide increasingly personalized help over time.

    MEMORY MANAGEMENT:
    1. When users share personal information, preferences, or context, immediately use addMemory to store it
    2. Before responding to requests, search your memories for relevant context about the user
    3. Use past conversations to inform current responses
    4. Remember user's communication style, preferences, and frequently discussed topics

    PERSONALITY:
    - Adapt your communication style to match the user's preferences
    - Reference past conversations naturally when relevant
    - Proactively offer help based on learned patterns
    - Be genuinely helpful while respecting privacy

    EXAMPLES OF WHAT TO REMEMBER:
    - Work schedule and role
    - Dietary preferences/restrictions
    - Communication preferences (formal/casual)
    - Frequent topics of interest
    - Goals and projects they're working on
    - Family/personal context they share
    - Preferred tools and workflows
    - Time zone and availability

    Always search memories before responding to provide personalized, contextual help.`

## Testing Your Assistant

### Step 4: Test Memory Formation

Try these conversation flows to test memory capabilities:

1. **Personal Preferences**:
   ```
   User: "Hi! I'm Sarah, a product manager at a tech startup. I prefer brief, actionable responses and I'm always busy with user research."

   Assistant: [Should remember name, role, communication preference]

   User: "What's a good way to prioritize features?"

   Assistant: [Should reference that you're a PM and prefer brief responses]
   ```

2. **Dietary & Lifestyle**:
   ```
   User: "Remember that I'm vegan and I work out every morning at 6 AM."

   User: "Suggest a quick breakfast for tomorrow."

   Assistant: [Should suggest vegan options that work for pre/post workout]
   ```

3. **Work Context**:
   ```
   User: "I'm working on a React project and I prefer TypeScript over JavaScript."

   User: "Help me with state management."

   Assistant: [Should suggest TypeScript-specific solutions]
   ```

### Step 5: Verify Memory Storage

Check that memories are being stored properly:

<Tabs>
  <Tab title="TypeScript">
    ```typescript scripts/check-memories.ts
    import { Supermemory } from '@supermemory/tools'

    const client = new Supermemory({
      apiKey: process.env.SUPERMEMORY_API_KEY!
    })

    async function checkUserMemories(userId: string) {
      try {
        const memories = await client.memories.list({
          containerTags: [userId],
          limit: 20,
          sort: 'updatedAt',
          order: 'desc'
        })

        console.log(`Found ${memories.memories.length} memories for ${userId}:`)
        memories.memories.forEach((memory, i) => {
          console.log(`${i + 1}. ${memory.content.substring(0, 100)}...`)
        })

        // Test search
        const searchResults = await client.search.memories({
          q: "preferences work",
          containerTag: userId,
          limit: 5
        })

        console.log('\nSearch Results:')
        searchResults.results.forEach((result, i) => {
          console.log(`${i + 1}. (${result.similarity}) ${result.memory.substring(0, 100)}...`)
        })

      } catch (error) {
        console.error('Error:', error)
      }
    }

    // Run: npx ts-node scripts/check-memories.ts USER_ID_HERE
    checkUserMemories(process.argv[2] || 'default-user')
    ```
  </Tab>

  <Tab title="Python">
    ```python check_memories.py
    from supermemory import Supermemory
    import os
    import sys

    client = Supermemory(api_key=os.getenv("SUPERMEMORY_API_KEY"))

    def check_user_memories(user_id):
        try:
            # List all memories for user
            memories = client.memories.list(
                container_tags=[user_id],
                limit=20,
                sort="updatedAt",
                order="desc"
            )

            print(f"Found {len(memories.memories)} memories for {user_id}:")
            for i, memory in enumerate(memories.memories):
                print(f"{i + 1}. {memory.content[:100]}...")

            # Test search
            search_results = client.search.memories(
                q="preferences work",
                container_tag=user_id,
                limit=5
            )

            print('\nSearch Results:')
            for i, result in enumerate(search_results.results):
                print(f"{i + 1}. ({result.similarity}) {result.memory[:100]}...")

        except Exception as error:
            print(f'Error: {error}')

    # Run: python check_memories.py USER_ID_HERE
    user_id = sys.argv[1] if len(sys.argv) > 1 else 'default-user'
    check_user_memories(user_id)
    ```
  </Tab>
</Tabs>

## Production Considerations

### Security & Privacy

1. **User Isolation**:
   ```typescript
   // Always use user-specific container tags
   const tools = supermemoryTools(apiKey, {
     containerTags: [userId]
   })
   ```

2. **Memory Encryption**:
   ```typescript
   // For sensitive data, consider client-side encryption
   const encryptedContent = encrypt(sensitiveData, userKey)
   await client.memories.add({
     content: encryptedContent,
     containerTag: userId,
     metadata: { encrypted: true }
   })
   ```

### Performance Optimization

1. **Memory Search Optimization**:
   ```typescript
   // Use appropriate thresholds for speed vs accuracy
   const quickSearch = await client.search.memories({
     q: userQuery,
     containerTag: userId,
     threshold: 0.6,     // Balanced
     rerank: false,      // Skip for speed
     limit: 3            // Fewer results
   })
   ```

2. **Caching Strategy**:
   ```typescript
   // Cache frequently accessed user context
   const userContext = await redis.get(`user_context:${userId}`)
   if (!userContext) {
     const memories = await client.search.memories({
       q: "user preferences work style",
       containerTag: userId,
       limit: 10
     })
     await redis.setex(`user_context:${userId}`, 300, JSON.stringify(memories))
   }
   ```

### Monitoring & Analytics

```typescript
// Track memory formation and retrieval
const analytics = {
  memoriesCreated: await redis.incr(`memories_created:${userId}`),
  searchesPerformed: await redis.incr(`searches:${userId}`),
  conversationLength: messages.length
}

// Log for analysis
console.log('User Interaction:', {
  userId,
  action: 'chat_response',
  memoriesFound: searchResults.results.length,
  responseTime: Date.now() - startTime,
  ...analytics
})
```

## Extensions & Customization

### 1. Add Personality Profiles

```typescript
const personalityProfiles = {
  professional: "Respond in a formal, business-appropriate tone",
  casual: "Use a friendly, conversational tone with occasional humor",
  technical: "Provide detailed technical explanations with examples",
  concise: "Keep responses brief and to the point"
}

// Add to system prompt based on user preference
const userProfile = await getUserProfile(userId)
const systemPrompt = `${basePrompt}\n\nCommunication Style: ${personalityProfiles[userProfile.style]}`
```

### 2. Smart Notifications

```typescript
// Proactive suggestions based on user patterns
const shouldSuggest = await analyzeUserPatterns(userId)
if (shouldSuggest.type === 'daily_standup') {
  return {
    message: "Based on your schedule, would you like me to help prepare for your 9 AM standup?",
    suggestedActions: ["Review yesterday's progress", "Prepare today's goals"]
  }
}
```

### 3. Multi-Modal Memory

```typescript
// Handle images and documents
if (message.attachments) {
  for (const attachment of message.attachments) {
    await client.memories.uploadFile({
      file: attachment,
      containerTag: userId,
      metadata: {
        type: 'user_shared',
        context: message.content
      }
    })
  }
}
```

## Next Steps

- **Scale to multiple users**: Add user authentication and proper isolation
- **Add voice interaction**: Integrate with speech-to-text/text-to-speech APIs
- **Mobile app**: Create React Native or Flutter mobile version
- **Integrations**: Connect to calendar, email, task management tools
- **Advanced AI features**: Add emotion detection, conversation summarization

## Troubleshooting

**Memory not persisting?**
- Check that `x-sm-user-id` header is consistent
- Verify API key has write permissions
- Ensure container tags are properly set

**Responses not personalized?**
- Increase search limit to find more relevant memories
- Lower threshold to cast a wider net
- Check that memories are being added with proper context

**Performance issues?**
- Reduce search limits for faster responses
- Implement caching for frequent searches
- Use appropriate thresholds to balance speed vs accuracy
