lumee brings the power of conversational AI directly into your DMS. Instead of digging through files, you can now chat with your documents and gain insights instantly. Ask lumee to summarize reports, compare contract versions, or clarify specific points โ and youโll receive clear answers with direct links to the source material. Since lumee is fully integrated into the permission system, it uses only the information you are authorized to access โ quickly, securely, and intuitively.
With lumee, you can access the knowledge in your documents directly. The AI assistant processes your questions in natural language and delivers well-founded answers from exactly the documents you are authorized to access โ from concise summaries and structured comparisons to targeted searches for facts.
With multilingual support and freely selectable AI models, lumee adapts flexibly to the needs of international teams. At the same time, all compliance requirements remain fully met: responses are based solely on documents you are authorized to access.
Note: AI-generated responses are based on statistical models. We recommend briefly reviewing the referenced documents for verification.
