Human in the Loop: independent human testing for your AI
Activated on engagement, with our partner Isahit
Human in the Loop is 56North's offer, activated on engagement with our partner Isahit, which provides for trained people to put your AI systems to the test and review their answers; every finding enters the Cockpit as dated evidence, with its author.
Why people, and not the vendor
A vendor cannot judge its own biases. Its governance tool exists to reassure you about its product. A regulator, an insurer or a large client will ask who, outside the vendor, has checked.
The Cockpit's automatic measurements tell you what an AI system costs and who uses it. They do not tell you whether an answer is right, biased or dangerous. For that, you need people who read.
What the offer covers
- Black-box testing campaigns. Bias, hallucinations, data leaks, procedures not followed: scenarios written for your use cases, run against your AI systems as they actually run.
- Two independent reviewers. Each case is judged by two independent people. When they disagree, a third opinion decides.
- Review of real conversations. Samples reviewed by people residing in the European Union, in teams formed for each client to our requirements, within the scope set in the purchase order.
- Test sets for your agents. Building and annotating the scenarios that then serve as your regression tests.
How a finding becomes evidence
Every finding enters the Cockpit as dated evidence, with its author. That is what an inspector accepts, and what no vendor tool can produce about its own AI. The evidence is attached to the systems in the AI register and to the obligations it documents.
Our partner: Isahit
Isahit is a French data-annotation company. The first European ethical-AI company certified B Corp: 1,000+ annotators, 7,500+ projects, references such as Airbus, Orange and L'Oréal.
The offer is activated on engagement: each campaign is prepared for one client, on its use cases, within the scope set in the purchase order.
Building and controlling stay separate
A Human in the Loop campaign never tests a system the Factory built or maintains for the same client. That is what makes the result count as an independent review.

Frequently asked questions
Who sees our data during testing?
Bias detection runs on fabricated scenarios, with none of your data. Reviewing real conversations is reserved for people residing in the EU, and specified in the purchase order.
Can we order testing campaigns on their own?
Yes: the Cockpit alone, Human in the Loop campaigns alone, or the Factory to run your systems. They work best together, but nothing forces you to take everything.
Is a testing campaign a certification?
No. We prepare an evidence file ready for an inspection. We never call it a certification.
