The Swiss-made legal AI built for German, Austrian and Swiss law, data sovereignty, and the way legal teams actually work — without the enterprise price tag or US data transfers.

For lawyers across the DACH region, protecting client data is a professional obligation, not a checkbox. CASUS hosts exclusively in Switzerland and the EU, with no data transfer to the US. Harvey runs on global infrastructure and offers in-region data residency as one option among many.
