Create a personalized AI Travel Assistant using Deja Vu. This guide provides step-by-step instructions and the complete code to get you started.

## Overview

The Personalized AI Travel Assistant uses Deja Vu to store and retrieve information across interactions, enabling a tailored travel planning experience. It integrates with OpenAI's GPT-4 model to provide detailed and context-aware responses to user queries.

## Setup

Install the required dependencies using pip:

```bash
pip install openai dejavu-memory
```

## Full Code Example

Here's the complete code to create and interact with a Personalized AI Travel Assistant using Deja Vu:

</CodeGroup>


## Key Components

- **Initialization**: The `PersonalTravelAssistant` class is initialized with the OpenAI client and Deja Vu memory setup.
- **Asking Questions**: The `ask_question` method sends a question to the AI, incorporates previous memories, and stores new information.
- **Memory Management**: The `get_memories` and search_memories methods handle retrieval and searching of stored memories.

## Usage

1. Set your OpenAI API key in the environment variable.
2. Instantiate the `PersonalTravelAssistant`.
3. Use the `main()` function to interact with the assistant in a loop.

## Conclusion

This Personalized AI Travel Assistant leverages Deja Vu's memory capabilities to provide context-aware responses. As you interact with it, the assistant learns and improves, offering increasingly personalized travel advice and information.
