Employees frequently need answers about HR policies, IT procedures, finance processes, internal guidelines, and operational runbooks. RAG and Knowledge AI can power internal assistants that retrieve relevant information from approved organisational sources and respond with supporting references. Specialist RAG AI services can configure document-level permissions so employees receive information appropriate to their access rights. RAG as a Service can be evaluated for internal assistance and knowledge discovery, depending on an organisation’s security and deployment requirements. Tailored RAG development services can integrate the assistant with Slack, Microsoft Teams, internal portals, and helpdesk tools, while maintaining audit trails, current knowledge, and escalation pathways for questions that require human support.
