Three planned demos
across our typical engagement surface.

Demo 01 · RAG & retrieval

A RAG assistant for Dutch legal documents.

Full chat interface grounded in Dutch law — asks Claude directly via the built-in API. Prompt chips, citation chips, and a sources panel that updates per response.

U
Mag een werkgever een proeftijd verlengen na ziekteverzuim?
ae
Nee — een proeftijd is wettelijk gefixeerd op de eerste werkdagen en kan niet eenzijdig worden verlengd. Zie BW art. 7:652 §4 en HR 13/06/2014 NJ 2014/348.
U
En als de werknemer schriftelijk instemt?
ae
Ook met instemming is verlenging nietig — de bepaling is van dwingend recht. 3 citations

02 Why these three

A retrieval system, a document-intake system, and a forecasting system.

Most of the work we ship looks like one of those three shapes — a knowledge interface, a structured-extraction pipeline, or a model wired into an operational decision. The demos exist so you can see how we approach each.

Each demo will ship with the source, the evaluation harness, and a short writeup of the trade-offs we made — not just a polished frontend.

Don't wait for the demos
if you have your own.

If one of these shapes matches what you're trying to build, talk to us — we'd rather scope yours than polish ours.
