AI in crosstax
Your AI from Switzerland or Europe.
Mistral is set up by default, further models on request – your AI computes in Switzerland or in Europe.
AI processing only in Switzerland or in Europe.
Which models crosstax supports
By default, everything is set up. crosstax sets up the other routes for your firm on request.
| Provider | Where the AI computes | Status |
|---|---|---|
 Mistral AI SAS, Paris (France) | Where the AI computesEU and EFTA (Norway) | StatusDefaultReady to go, no contract of your own. |
 Open Swiss model (EPFL, ETH Zurich, CSCS), through Infomaniak. | Where the AI computesSwitzerland | StatusOn requestcrosstax sets it up for your firm. |

  Your own Langdock access, including Claude and OpenAI through Langdock. | Where the AI computesYour instance’s EU region | StatusOn requestYour own Langdock contract and key; crosstax transmits on your behalf. |
Every route runs the same AI features: reading documents, recognising the document type, suggesting values, and AI assistant.
Text recognition stays with Mistral. Scanned documents are read by Mistral using text recognition (OCR) – even if your firm uses Langdock or Apertus is doing the work. Only the recognised text then goes to the chosen model.
Each of these routes is also available on request with your firm’s own key (bring your own key).

What the AI does in crosstax
The AI works where documents and details arrive: it reads, sorts and suggests.
Reading documents
The AI reads values from uploaded documents. For each value it gives the page and how confident it is.
Recognising the document type
The AI recognises the document type and the country a document comes from. It does not overwrite a category your firm sets.
Suggesting values
When the suggestion feature is switched on, the AI suggests values for open questions – from details already captured and stored texts of uploaded documents.
AI assistant
Your team asks about one client; the AI answers from that client’s details, answers and documents – through the same provider. Every source is a link into the file; crosstax does not show a link that did not come from this request.
What the AI does not do
- No training by crosstaxNC Labs GmbH does not use your firm’s data to train AI models – this is set out in the data processing agreement.
- The AI does not send anythingThe AI does not submit a case, approve anything or sign anything. Your clients and your team do that.
Labelled under the EU AI Act
Wherever you or your clients work with the AI, a permanent note says that an AI is involved (Art. 50 of the EU AI Act). Values and texts generated by an AI that your clients see carry this mark:
