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).
