Private RAG FAQ

How is this different from using ChatGPT directly?

Your private AI assistant is trained exclusively on your business knowledge and never shares data with external services. It knows your specific procedures, policies, and context.

Where is our data stored and who has access?

Your knowledge base and AI models are hosted in Australian data centres with strict access controls. Your data never leaves the designated environment.

How accurate are the AI responses?

The system provides confidence scores with each answer and includes source citations. When unsure, it clearly indicates uncertainty rather than guessing.

Can we control which team members access which information?

Yes, we implement role-based access controls that mirror your existing security policies, ensuring users only see information they're authorised to access.

How long does implementation typically take?

After initial knowledge audit (3 weeks), most private AI systems are live within 8-10 weeks, including comprehensive testing and team training.

What's the ROI on a private AI knowledge base?

Most teams see immediate productivity gains from faster information access, with full ROI typically achieved within 6-9 months through reduced onboarding time and improved decision-making speed.
