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).
