For those evaluating Kate
This page is for the people who have to sign off: IT, security, whoever signs. No vague formulas: where the data sits function by function, the commitments we make, and the things Kate does not do today.
The chain
Kate is not a single block: it is five functions, each with a job and a place. Everything that holds or touches your notes is in the European Union. We don’t publish supplier names here: they are part of the data processing agreement and we give them to you in writing on request, even before you sign.
| Function | What it does | Where |
|---|---|---|
| Database and archive | Notes, links, audiences, permissions, history, attachments and photos | European Union |
| Application and API | This is where the code that touches your notes runs. Calls to your systems also leave from here, with a fixed IP address | European Union |
| Semantic search | Turns notes into vectors, to find the right ones | European Union |
| Answer generation | Writes the text from the retrieved notes | European Union |
| Network and public pages | DNS, protection and delivery of this website | None of your content |
Commitments
Model providers do not use your questions, your notes or the answers to train their models. It is written into the contracts we sign with them.
The model receives the relevant notes at the moment an answer is needed, and does not keep them. The archive is the database, and it is yours.
The perimeter is enforced by the database, not by the prompt. Someone without access to an audience does not see those notes, not even inside an answer.
To assist you, a person at Thingz must open a support session: with a stated reason, an expiry, and a trace that stays in your logs.
Administrators see which notes were used and how confident Kate was, without the author of the question. It is there to understand answers, not to watch people.
Kate’s calls to your systems leave from a single address, which you can allowlist on your firewall.
GDPR
The client company is the data controller: it decides what goes into Kate, who sees it and who can change it. Thingz is the processor and acts on your instructions. The suppliers performing these functions are sub-processors: the full list, with each name and location, is attached to the agreement and provided on request.
Integrations
We would rather say it plainly than let it be assumed. Kate is used from the web and queried through the API. Any other channel — Teams, a phone system, an intranet, an internal app — is built on the API, by your IT department or your technology partner: the knowledge stays in one place, no copies are made. We concentrate on the product.
Migration
Kate reads your documents and proposes notes, split by topic, with suggested tags and links. But a note becomes knowledge when one of your people confirms it: that is exactly the point of the product, and it means the start is not free.
Whatever you don’t find here, just ask.
