/What we do
Two activities, one standard.
70% of employees already use AI. 67% of them with tools that are not approved.
NYMETRA lets regulated professions work with AI on real case files without exposing their clients’ identities.

/Our commitments
What guides our choices.
Business before technology.
We start from your processes and constraints, not from a ready-made solution to sell you.
Confidentiality by design.
Local or private processing when needed. Your data is not our business model.
Direct contacts.
You talk to the people who design and build your tools.
Figures with sources.
We publish our measurements with their limits: 94 to 96% detection for NYMETRA depending on the run, on 30 documents never seen before.
