AI that stays in-house

Your knowledge.Your models.Your server.

Get answers from your own documents – on a server you control, with models you choose and assistants that know your trade. Like an onion, every layer protects the one inside; at the heart lies your data.

Peel back the layers
Layer by layer

Four layers around your data

01

Your server

Your AI runs where your data already is – on your own server, without a cloud subscription. Every update arrives checked, with a way back.
02

Your know-how

Manuals, archives and drawings answer your questions – every answer with the passage it comes from, so you can check it.
03

Sovereign AI

You decide who processes your data: models on your own hardware, European providers or – only where you allow it – others. If one fails, your assistants keep working.
04

Tailored assistants

Your team, your website visitors and your specialists each get an assistant that knows exactly what it needs – from aluminium extrusion to the editorial office.
Sovereignty by design

You decide how far each document may travel

Mark a document as confidential once, and it stays with the models you trust most – no matter who asks or which assistant answers. Public material may travel further.

  • Confidential stays in-house
  • Everyone sees only what they may see
  • Every answer shows its source

Find

Only the knowledge you have shared with this assistant is searched.

Check

Answer
