A Private Microsoft 365 Copilot for Secure SharePoint AI
NexusAI enables organizations to chat with SharePoint data securely using Azure OpenAI — fully permission-aware and deployed inside your tenant.
The Enterprise Knowledge Problem
Information exists everywhere — answers do not
Information Silos
Critical knowledge spread across thousands of SharePoint sites and documents with no unified access.
Search Fatigue
Keyword search returns endless file lists, not the answers your team needs to make decisions.
Security Risks
Public AI tools ignore enterprise permissions and put your sensitive data at risk of leakage.
Low AI Adoption
Complex tools outside Teams fail to gain traction, wasting AI investment and reducing productivity.
