## **Introduction**

Aspose.Slides is a powerful API for programmatically managing PowerPoint presentations. In addition to creating, editing, and converting slides, it offers AI-driven features - such as the Presentation Translation API for multilingual slide content.

## **How It Works**

Aspose.Slides does not include built-in AI capabilities but integrates with external AI models over the internet. This functionality is exposed via the [SlidesAIAgent](https://reference.aspose.com/slides/java/com.aspose.slides/slidesaiagent/) class, which uses an implementation of the [IAIWebClient](https://reference.aspose.com/slides/java/com.aspose.slides/iaiwebclient/) interface to communicate with AI services.

You can use the built-in [OpenAIWebClient](https://reference.aspose.com/slides/java/com.aspose.slides/openaiwebclient/) to connect to OpenAI’s API or implement your own [IAIWebClient](https://reference.aspose.com/slides/java/com.aspose.slides/iaiwebclient/) to use a different AI provider or language model.

Aspose.Slides handles the communication, parses the AI responses, and intelligently inserts translated content while preserving the original slide layout and formatting.

Note that the OpenAI API is a paid service, so you will need to create an account and supply your API key when using the built-in [OpenAIWebClient](https://reference.aspose.com/slides/java/com.aspose.slides/openaiwebclient/).

## **Example**

In this example, we translate a PowerPoint presentation into Japanese using the built-in [OpenAIWebClient](https://reference.aspose.com/slides/java/com.aspose.slides/openaiwebclient/) with a specified OpenAI [model](https://platform.openai.com/docs/models).

```java
import com.aspose.slides.*;

// Load a presentation to translate.
Presentation presentation = new Presentation("sample.pptx");

// Create an AI client with OpenAIWebClient, specifying your model and API key.
OpenAIWebClient aiWebClient = new OpenAIWebClient("gpt-4o-mini", "apiKey", null);

try {
    // Initialize SlidesAIAgent with the AI client.
    SlidesAIAgent aiAgent = new SlidesAIAgent(aiWebClient);

    // Translate the presentation to Japanese.
    aiAgent.translate(presentation, "japanese");

    // Save the translated presentation as a PDF.
    presentation.save("sample_jp.pdf", SaveFormat.Pdf);
} finally {
    aiWebClient.close();
    presentation.dispose();
}
```

By default, the built-in [OpenAIWebClient](https://reference.aspose.com/slides/java/com.aspose.slides/openaiwebclient/) creates and manages its own internal [HttpURLConnection](https://docs.oracle.com/javase/8/docs/api/java/net/HttpURLConnection.html) instance, handling its lifecycle automatically. However, if you prefer to manage the [HttpURLConnection](https://docs.oracle.com/javase/8/docs/api/java/net/HttpURLConnection.html) yourself — primarily to configure essential settings like a proxy, or to use an [URLStreamHandlerFactory](https://docs.oracle.com/javase/8/docs/api/java/net/URLStreamHandlerFactory.html) or a different [HttpClient](https://docs.oracle.com/en/java/javase/11/docs/api/java.net.http/java/net/http/HttpClient.html) for better resource management and performance — you can provide your own `HttpURLConnection` instance when constructing the [OpenAIWebClient](https://reference.aspose.com/slides/java/com.aspose.slides/openaiwebclient/).

```java
import com.aspose.slides.*;
import java.net.HttpURLConnection;
import java.net.InetSocketAddress;
import java.net.Proxy;
import java.net.URL;

// Configure an HttpURLConnection instance yourself (custom timeouts, proxy settings, etc.).
Proxy proxy = new Proxy(Proxy.Type.HTTP, new InetSocketAddress("proxy.example.com", 8080));
HttpURLConnection urlConnection = (HttpURLConnection)new URL("https://api.openai.com/v1/chat/completions").openConnection(proxy);
urlConnection.setConnectTimeout(30000);
urlConnection.setReadTimeout(60000);

OpenAIWebClient aiWebClient = new OpenAIWebClient("gpt-4o-mini", "apiKey", null, urlConnection);
```
