NENNA Chat
The Privacy-First AI Platform
The secure AI platform that automatically masks sensitive data, integrates all leading models and runs on German infrastructure. Legally compliant, including under Section 203 of the German Criminal Code.
Data-secure AI usage for the entire enterprise
Use any AI model without revealing sensitive data.
At present, your team types sensitive company data directly into public AI tools, handing it over unprotected. NENNA Chat automatically masks this data in real time before it reaches the AI, and only re-inserts your actual data in the response.

Mastering your knowledge with control
Let AI work with your company knowledge.
Incorporate your own expertise, connect internal sources, and build prompt libraries and agents. Everything is housed within a secure data platform on German infrastructure. The AI responds within the context of your company, ensuring that this context never leaves your organisation.
Independent & sovereign
Committing to a single AI tool can leave you stranded if the model becomes outdated, more expensive or is shut down entirely. NENNA Chat solves this by bringing all the leading models together on one platform, allowing you to switch between them at any time. All with complete data sovereignty. Over 50 models, including image generation.

From chat straight to your letter template
The File Agent delivers ready-to-use files directly in the chat.
The NENNA File Agent has been designed to offer our business clients maximum control and efficiency. It connects NENNA to a real computing environment, enabling AI agents to write and execute code, and deliver the results of complex analyses directly within the final Excel or other spreadsheet files. This eliminates the need for tedious copying and pasting or switching between different tools. In doing so, we empower businesses to leverage AI with greater productivity and data security.

Reason Why for NENNA Chat
Security, choice and context combined on one platform.
Sensitive data remains secure
We mask the sensitive content in your team's inputs before they even reach an AI model. This happens automatically, ensuring confidential information is reliably protected.
The best model for every task, all in one place
Your team can switch seamlessly between all leading AI models without ever having to leave the chat history.
Answers that fit your business
The AI works within the context of your saved knowledge, attached notes, or documents, rather than remaining generic.
