What problem does it solve? Adding AI-driven language operations like proofreading, translation, summarization, and contextual Q&A to .NET document processing workflows normally requires custom integration between LLM providers and document engines. This Skill provides the DevExpress AI-Powered Extensions for Office File API, which connect any IChatClient-compatible model (Azure OpenAI, OpenAI, Ollama, Gemini, ONNX) directly to Word, PDF, and PowerPoint processing. ## Core Features & Use Cases - Proofread and Translate Documents: Apply grammar, spelling, and style corrections or translate entire documents, specific paragraphs, slides, or PDF page regions while preserving formatting. - Summarize and Ask AI (RAG): Generate abstractive or extractive summaries and answer natural language questions about document content using retrieval-augmented generation. - Multi-Provider Support: Register Azure OpenAI, OpenAI, Ollama, Google Gemini, ONNX Runtime, or AI Foundry Local through the Microsoft.Extensions.AI abstraction in console or ASP.NET Core apps. - Use Case: A developer needs to translate a German contract PDF into English on a server. They load the PDF with PdfDocumentProcessor, call TranslateAsync with the target culture, receive the translated text, and render it onto a new page. ## Quick Start Ask the AI to set up the DevExpress AI document processing service with your chosen provider and proofread a Word document, then save the corrected result.
