What is Marvin?

Marvin is the AI Assistant built into NIZU Cloud WorkSpace. It lets clients, leads and staff ask plain-language questions about their own data — for example “tell me about invoice #586” or “what is overdue this month?” — and get a clear, conversational answer.

How Marvin is different

Most AI assistants hand your data to the language model and let it decide what to do. Marvin does the opposite. The NIZU backend identifies who is asking, checks they are allowed to see the requested record, and fetches that record live from NIZU. Only then is a language model asked to phrase the answer. The model never authorizes access and never fetches data on its own.

Core ideas

• NIZU is the single source of truth. Records are fetched live, never copied.
• The model is a language layer, not a data layer. It only phrases answers.
• The provider is swappable. A self-hosted model in production, a third-party API in development, or a per-workspace choice — changed with one setting.
• Real data only meets a trusted provider. Third-party cloud APIs see fake data only.

Who is it for?

Marvin is available to staff in the main app and to clients and leads in the portal. Each person sees only their own data and their own conversation history with Marvin, while administrators can review conversations for quality.

Why it matters

Marvin turns NIZU into something you can simply talk to. Instead of navigating menus and filters, you ask a question and get an answer — without ever exposing data to a system that should not see it.
