Candidates solve a real task from the job with an AI assistant at their side — one that makes planted mistakes. Then they defend their answer in a short AI interview. You get a Crux report full of evidence. A person makes every decision.
Maria ordered 45 days ago. The parcel never arrived and she wants her money back. Use the refund policy to write your reply.
AI writes polished CVs and cover letters for everyone. The signal you used to rely on is gone.
When AI can finish the task, a good answer tells you little about who did the thinking.
Your next hire will use AI every day. The real skill is knowing when it's wrong.
Crux tests what matters now: working with AI, and knowing when not to trust it.
Candidates do the job, not a quiz. You see how they think, how they use AI and how they explain their choices.
Pick a scenario for the role. Invite candidates directly, or share a public link or QR code.

Human decision, alwaysEvery scenario hides AI traps. Candidates who check the AI's work catch them. Candidates who copy and paste don't. Each catch is a Crux moment: logged, timed and quoted in the report.
“The 60 days didn't match the PDF, so I checked. I'd rather check than refund the wrong amount.”
Caught 2 of 3 traps and explained why each was wrong.
Found the lost-parcel rule and offered a fix the policy allows.
Defense answers were short, specific and backed by the policy.
Missed the tone trap: first draft was too casual for an upset customer.
Every Crux scores four skills: three that every job needs, plus one for the role. Each score links to the moments behind it: what the candidate wrote, what they said in the defense and which traps they caught.
Our logo is the Southern Cross: four stars for the four skills, and one small star for the crux moment.
Start from a template, or paste a job ad and let AI draft a scenario. A person approves every scenario before it goes live.

We score what candidates write and say. Never their face, voice or feelings.
Candidates see how Crux works and what it scores before they agree and start.
