AI-powered Extensions for DevExpress Document Processing APIs
DevExpress Document Processing APIs include backend-ready AI extensions for PDF, Word, and PowerPoint documents.
- Summarize Documents: Generate concise summaries for reports, contracts, or presentations.
- Translate & Proofread: Translate documents or fix grammar and spelling (preserve layout and formatting).
- Ask Questions: Query PDF, Word, or PowerPoint files to extract insights.
These AI-powered extensions communicate with language models via the Microsoft.Extensions.AI library and its IChatClient interface. You can use cloud-based services (Azure OpenAI, OpenAI, Google Gemini) or local models (Ollama, ONNX Runtime, AI Foundry Local).
Code Example - Get Started
Install NuGet packages: DevExpress Extensions
Install the NuGet package that contains DevExpress AI-powered Extensions: DevExpress.AIIntegration.Docs.
dotnet add package DevExpress.AIIntegration.Docs
Install NuGet packages: AI Service
Install NuGet packages required by your AI service of choice. This example uses Azure OpenAI and requires the following packages:
dotnet add package Azure.AI.OpenAI --version 2.2.0-beta.4
dotnet add package Microsoft.Extensions.AI.OpenAI --version 9.5.0-preview.1.25265.7
To see package lists required by different AI Services, refer to the following help topic: AI Extensions - Prerequisites.

using Azure.AI.OpenAI;
using DevExpress.AIIntegration;
using Microsoft.Extensions.AI;
using System.ClientModel;
using DevExpress.XtraRichEdit;
using DevExpress.Docs.Presentation;
// Obtain Azure OpenAI credentials
string azureOpenAIEndpoint = Environment.GetEnvironmentVariable({YOUR_AZURE_ENDPOINT});
string azureOpenAIKey = Environment.GetEnvironmentVariable({YOUR_AZURE_OPENAI_APIKEY});
// Register Azure OpenAI client
IChatClient client = new AzureOpenAIClient(new Uri(azureOpenAIEndpoint),
new ApiKeyCredential(azureOpenAIKey)).GetChatClient("gpt-4o-mini").AsIChatClient();
AIExtensionsContainerDefault defaultAIExtensionsContainer = AIExtensionsContainerConsole.CreateDefaultAIExtensionContainer(client);
// Create AI-powered document service
var aiService = defaultAIExtensionsContainer.CreateAIDocProcessingService();
Translate a Word Document
// Initialize a Word document processor and upload a file
var wordProcessor = new RichEditDocumentServer();
wordProcessor.LoadDocument("Document.docx");
// Translate the document and save the result
await aiService.TranslateAsync(wordProcessor, new CultureInfo("fr-FR"), CancellationToken.None);
MemoryStream translatedDocStream = new MemoryStream();
wordProcessor.SaveDocument(translatedDocStream, DocumentFormat.OpenXml);
Translate a PowerPoint Presentation
// Initialize a Presentation object and upload a file
FileStream fs = File.OpenRead("presentation.pptx");
var presentation = new Presentation(fs);
// Translate the presentation and save the result
await aiService.TranslateAsync(presentation, new CultureInfo("fr-FR"), CancellationToken.None);
MemoryStream translatedPresentationStream = new MemoryStream();
