AI Chat v4: A full-featured AI Assistant integrated with your APIs and Auth
Multi-provider chat, RAG, PDF Studio, tools, skills, mcp, projects and agents in one App - unleashing AI intelligence on your existing APIs
ServiceStack’s AI Chat v4 is presented as a modular, self-hosted platform that integrates sophisticated artificial intelligence directly into existing application infrastructures. The system unifies multi-provider LLM access, document-based RAG, and automated API tools under a single security and authentication boundary.
By leveraging an extension-based architecture, developers can customize the interface, manage per-user workspaces through Projects, and monitor usage with built-in analytics.
It specifically bridges the gap between general consumer chatbots and secure enterprise needs by allowing AI assistants to interact with authorized business APIs and generate production-ready documents via PDF Studio.
This update transforms the tool from a simple chat interface into a comprehensive AI orchestration layer that respects existing user permissions and data sovereignty.
