Don't fight AI.
Score how people use it.
The AI assistant is switched on during every test. We grade how well you use it, then ask you to defend your reasoning.
Tests AI Can't Fake
Every answer is paired with a “defend your reasoning” step, graded on its own. A pasted answer survives the first step. It cannot survive the second.
Scored Fairly
AI grades in seconds. Humans review the close calls, blind to identity. The ranking AI is barred from using names or protected attributes.
Proof You Own
Results become Open Badges 3.0 verifiable credentials, signed, anchored on-chain, and independently verifiable by anyone, anywhere.
Scored out
of 1,000.
A resilient multi-model AI engine grades every answer against a clear rubric and returns a headline skill score with a per-skill breakdown. Low-confidence results are automatically escalated to a human reviewer.
Open Badges 3.0
Earn it once.
Carry it anywhere.
Every credential is an Open Badges 3.0 standard artifact, cryptographically signed and anchored on-chain — instantly checkable by any recruiter or institution in the world, without taking Redrob's word for it.

One standard of proof.

The old way of proving skill.

Verified, two-step, blind
Good questions.
What makes Redrob Skills different from a normal online test?+
Every question has two stages: answer, then defend your reasoning. The AI assistant is switched on during the test, and how you use it is scored too — so a pasted answer can survive the first step, but not the second.
How is my test scored?+
A resilient multi-model AI engine grades every answer against a clear rubric and returns a headline skill score out of 1,000 with a per-skill breakdown. Low-confidence results are automatically escalated to a human reviewer, and you can always request a review.
What do I actually get after passing a test?+
A verifiable Open Badges 3.0 credential, cryptographically signed and anchored on Polygon. It's yours to keep, and anyone can independently verify it through four checks: signature, status, integrity, and on-chain anchor.
Is my personal data exposed on the blockchain?+
No. Your identity is hashed and never stored in the clear, and only anonymous proofs go on-chain. You can choose to publish your exact score, but that's a deliberate, one-way action you control.
Can recruiters and institutions build their own tests and certifications?+
Yes. Recruiters get a guided job skill-test builder with AI-suggested questions and a bias-guarded AI shortlist. Institutions get a certification builder with AI-drafted criteria, and both are gated behind a vetted-approval process to keep the marketplace trustworthy.
How is scoring kept fair?+
Human reviewers see skill, not identity — only an anonymous reference. The AI that ranks candidates is barred from using names or protected attributes, and every assessment carries a built-in fairness audit.
Stop faking skill.
Start proving it.
Take a skill test, defend your reasoning, and walk away with a credential you own — verifiable by anyone, anywhere.
