lumee: Your AI assistant for intelligent document management

Someone is using a desktop with a PDF file, a chatbot, and a help window open on the screen; a potted plant sits next to the keyboard.

Smart answers instead of endless searching

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.


Intelligent information processing

Faster compilation of information

Reduced search and reading times

Efficient document analysis

What makes lumee unique?

Business expertise meets AI intelligence

While ChatGPT and other AI systems rely solely on general knowledge, lumee combines the language capabilities of modern AI directly with your companyโ€™s data. With RAG technology (Retrieval Augmented Generation), lumee delivers precise answers to your specific documents and business processes โ€“ knowledge that no generic AI system can provide.

Security through seamless integration

lumee fully respects the DMS permission system. Unlike the direct use of external AI systems, lumee ensures that users can only access information they are authorized to view. This seamless integration makes lumee a secure addition to your DMS.

Always up to date

lumee automatically synchronizes with your document base. New documents are available immediately, and any changes or deletions are instantly reflected. This continuous update runs in the background and ensures that you always work with the most current version of your business data.

Typical use cases

Understand & summarize documents

lumee reads your documents, identifies the key information, and delivers precise summaries in seconds.
