Arminius Chat

Let your people use AI.
Keep your data in-house.

Arminius Chat works just like ChatGPT, but it runs on an appliance on your premises. Staff sign in with their company account, and a contract they paste in never leaves the building.

I want this for our company

Looks like ChatGPT.
Runs on your premises.

Your staff have nothing new to learn. Management and IT can see who uses the AI, and everything runs inside the company network.

Give me a short summary of the NDA with our supplier. The contract is attached.
NDA with supplier: summary (signed 12 Mar 2025)

Scope: trade secrets, technical documentation, price lists
Term: 3 years from signing, continuing after the business relationship ends
Exceptions: publicly available information, court proceedings

Note: the contract does not define ‘confidential information’. I recommend adding a definition before the next round of negotiations.

The problem

A contract pasted into a public chatbot is no longer just yours

People paste contracts, financial reports and client data into public AI tools because it saves them time. IT often has no idea. Banning these tools won't help when people have AI on their phones anyway.

The solution

Give them a tool they are allowed to use

What works best is for management to give people an approved tool that is just as convenient as the public one. Arminius Chat runs in your network, and you set the rules.

Arminius Chat
  • → Runs in your network; data never leaves it
  • → Company-wide rules set in one place
  • → Designed for GDPR and EU AI Act compliance
  • → Log: who, when and in which mode
  • → No per-question charges

For IT and security

What your IT team sees and controls

Usage overview

Employees work in a company tool instead of personal accounts. The admin console shows who used the AI, when and in which mode.

Query log

Every query is recorded: who, when, mode and groups. Question text is logged only if the company enables this.

Group-based access

You grant access to modes and document sources by user group, whether the groups come from Active Directory or are created in the system itself. Access is checked with every question.

GDPR and the EU AI Act

Personal data does not leave your organisation and is processed in your network in the EU. That is a solid basis for GDPR and AI Act compliance.

Single sign-on

Connects to Active Directory or LDAP. One company account for the chat and all modules.

Isolated from the internet

Services have no internet access, and monitoring checks this continuously.

Frequently asked questions

Questions about Arminius Chat

How is Arminius Chat different from public ChatGPT?

It runs on the appliance in your network, employees sign in with their company account and every question is logged. Company data never goes to any AI provider, and there is no charge per question.

Which modes does Arminius Chat have?

The AI mode for everyday work such as questions, translations and summaries, and the AI (thinking) mode for more thorough analysis of longer texts and contracts, which takes longer.

Can employees attach documents?

Yes: PDF, Word and images including photos and screenshots. Everything is processed locally on the appliance.

Is Chat required for the other modules?

Yes. Arminius Chat is the base of the solution, and a single sign-in covers the chat and all modules.

How do we stop employees using public AI tools?

Bans are hard to enforce. It works better to give people an approved tool that is just as convenient and runs under the company's control, which is exactly what Arminius Chat is.
