🧠 Implement mem0 User Memory System

Overview

Integrate mem0 for long-term user memory — the bot remembers conversations, preferences, and patterns for personalized support.

---

Goals

• Persistent memory across sessions
• User owns their memory
• Privacy-compliant storage
• Fast retrieval for real-time responses
• Cross-device synchronization

---

Memory Categories

Category	Examples	Retention
Preferences	Tone, frequency, avatar	Forever
Patterns	Check-in times, triggers	User-controlled
Conversations	Recent chat history	30-90 days
Milestones	Achievements celebrated	Forever
Coping strategies	What worked	User-controlled

---

Technical Integration

mem0 Setup

import { Memory } from '@mem0/vercel-ai-sdk';

const memory = new Memory({
  apiKey: process.env.MEM0_API_KEY,
  userId: hashedUserId,  // Anonymized
  encryption: true,
  retention: {
    conversations: '90d',
    patterns: '1y',
    preferences: 'forever'
  }
});

Memory Operations

// Store conversation
memory.add(message, { type: 'conversation', timestamp });

// Store learned pattern
memory.add(pattern, { type: 'pattern', confidence });

// Retrieve relevant context
const context = await memory.search(query, { limit: 5 });

// Get user preferences
const prefs = await memory.get('preferences');

Memory Architecture

Storage Layers

1. Local Cache — Recent conversations (fast access)
2. Encrypted Cloud — Full memory (sync across devices)
3. mem0 Service — Vector search, pattern matching

Sync Strategy

• Real-time for critical data (preferences)
• Batch for large data (conversation history)
• Conflict resolution: last-write-wins with merge

---

Privacy & Security

Encryption

• End-to-end encryption for all memories
• User-controlled encryption keys
• mem0 cannot access plaintext

Data Residency

• EU data stays in EU
• US data stays in US
• Configurable by deployment

User Control

• View all stored memories
• Delete specific memories
• Export all memories
• Set retention policies

---

Implementation Tasks

• Set up mem0 SDK integration
• Configure encryption
• Implement memory storage layer
• Build memory retrieval API
• Add memory search functionality
• Implement cross-device sync
• Create memory management UI
• Add memory export/delete
• Write memory integration tests

---

Acceptance Criteria

• Memories persist across sessions
• Retrieval < 500ms for real-time use
• Sync works across devices
• Encryption verified
• User can view/delete memories
• Export produces readable JSON
• No data loss during sync conflicts
