Common questions

FAQ

Is it really free?

Yes. Assessments, AI grading, and credential issuance are free for learners. Employers can verify shared credentials without an account.

How is the AI grading fair?

Every score includes the exact rubric dimensions used, the AI's reasoning, and evidence quotes pulled directly from your submission. You can see exactly why you got each score — no black boxes.

What is a W3C Verifiable Credential?

It's an open internet standard for tamper-proof digital credentials. Your credential is cryptographically signed with our DID key. Anyone can verify it hasn't been altered — even if Maxx Engage shut down tomorrow.

Can employers trust these credentials?

Every credential links to a public verify page where anyone can confirm the cryptographic signature, the score, the rubric, and the date. No need to contact us — the math is the proof.

What if I disagree with my score?

You can flag any review for human review. Our team reads the submission and the AI's reasoning and can override the score. You can also retake assessments to improve.

Do credentials expire?

Skills decay. Each credential has a stated half-life — after that, your score is gradually reduced to reflect that the skill may have been practised less recently. Refreshing with a new submission resets the clock.
