+
+You can create a personalised AI Companion using Mem0. This guide will walk you through the necessary steps and provide the complete code to get you started.
+
+## Overview
+
+The Personalized AI Companion leverages Mem0 to retain information across interactions, enabling a tailored learning experience. It creates separate memories for both the user and the companion. By integrating with OpenAI's GPT-4 model, the companion can provide detailed and context-aware responses to user queries.
+
+## Setup
+Before you begin, ensure you have the required dependencies installed. You can install the necessary packages using pip:
+
+```bash
+pip install openai mem0ai
+```
+
+## Full Code Example
+
+Below is the complete code to create and interact with an AI Companion using Mem0:
+
+```python
+from openai import OpenAI
+from mem0 import Memory
+import os
+
+# Set the OpenAI API key
+os.environ['OPENAI_API_KEY'] = 'sk-xxx'
+
+# Initialize the OpenAI client
+client = OpenAI()

+ai_companion = Companion(user_id, companion_id)
+
+# Ask a question
+ai_companion.ask("Ive been missing you. What have you been up to off late?")
+```
+
+### Fetching Memories
+
+You can fetch all the memories at any point in time using the following code:
+
+```python
+def print_memories(user_id, label):
+    print(f"\n{label} Memories:")
+    memories = ai_companion.get_memories(user_id=user_id)
+    if memories:
+        for m in memories:
+            print(f"- {m['text']}")
+    else:
+        print("No memories found.")
+
+# Print user memories
+print_memories(user_id, "User")
+
+# Print companion memories
+print_memories(companion_id, "Companion")
+```
+
+### Key Points
+
+- **Initialization**: The Companion class is initialized with the necessary memory configuration and OpenAI client setup.
+- **Asking Questions**: The ask method sends a question to the AI and stores the relevant information in memory.
+- **Retrieving Memories**: The get_memories method fetches all stored memories associated with a user.
+
+### Conclusion
+
+As the conversation progresses, Mem0's memory automatically updates based on the interactions, providing a continuously improving personalized experience. This setup ensures that the AI Companion can offer contextually relevant and accurate responses, enhancing the user's experience.
