Smartchat Docs

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, it delivers GDPR compliance, audit logging, role-based access, and contractually agreed service levels as part of the product — operated on T-Cloud infrastructure certified to BSI-C5 and ISO 27017/27018 — 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.

Our chat interface builds on a fork of OpenWebUI v0.6.5 (the last release under the open-source BSD-3 license¹). The open-source version did not meet enterprise standards, so we fixed it with multi-tenancy, compliance, and security hardening as first-class features.

These docs walk through the architecture, the available models, RAG configuration, the API, and how to integrate Smartchat into your existing systems.

Part of AI Foundation Services

Smartchat is one product within AI Foundation Services. For documentation on the broader platform, including LLM API access, model catalog, billing, and platform administration, visit the AI Foundation Services documentation.

What Smartchat adds beyond OpenWebUI

Multi-Tenancy

Fully isolated tenants (Spaces) provide strict data separation to account for different confidentiality levels and organizational boundaries.

Enterprise RBAC

Fine-grained role-based access control across spaces, admin panels, and API endpoints with enterprise SSO integration.

Async Ingestion Pipeline

Fully asynchronous, distributed document ingestion that runs in the background with no impact on the user experience. Scales horizontally to handle even the largest enterprise document volumes, both in total size and parallel throughput.

Security Hardening

Hardened against the OWASP Top 10, certified and penetration-tested by Deutsche Telekom security professionals. Sandboxed code execution, input validation, and attack surface reduction beyond what the open-source version offers.

Compliance & Accessibility

GDPR-compliant application operated on T-Cloud infrastructure certified to BSI-C5 and ISO 27017/27018, and built to meet enterprise accessibility requirements.

Fully Sovereign & European

Sovereign across the entire stack: the application, the cloud, the LLMs, and the infrastructure down to the GPUs are all European and operated by T-Systems in Germany.
