CoworkOne — AI Workspace with Governed AI on Microsoft 365

The challenge

Companies wanted to use AI with their documents, email and Microsoft 365 data without losing governance: who uses what, with which permissions and at what cost.

The solution

CoworkOne was built as a monorepo with Next.js 16, NestJS 11, Prisma 7 and PostgreSQL 18, with a central console for licenses and remote updates for each instance. It integrates with Entra ID via certificate, SharePoint, Exchange, Power BI and Fabric, the Microsoft 365 Copilot APIs and Azure AI Foundry, and shows the real cost of AI with Azure Cost Management. Every secret is encrypted with AES-256-GCM from a root of trust unique to each instance. It is backed by 73 migrations and 330 test files.
