SmartChat
SmartChat is a managed, sovereign offering for AI-assisted knowledge work — featuring chat with your documents, deep research, and data and tool integrations. Built on T-Systems AI Foundation Services and operated on T-Cloud, which is certified to BSI-C5 and ISO 27017/27018, it delivers GDPR compliance, audit logging, role-based access, and a contractually agreed service level as part of the product rather than leaving them as your team’s homework.
In practice, SmartChat is what you reach for when the chat UI is the easy part and the hard part is running it safely for regulated workloads: healthcare, public sector, finance, or any context where data residency, professional secrecy, and operational accountability matter most.
