Credentials for human skills

Prove what you know. Just talk.

Supraversity assesses real-world skills through live conversation, structured evaluation, and signed certificates. The result is a credential built from how you think, explain, and apply what you know.

AI colleague acts like a thoughtful colleague

It asks open-ended questions, introduces calibrated misconceptions, and adapts to demonstrated depth.

“If everything is stored in UTC, why do scheduling bugs still appear around DST transitions?”
“Because normalization solves storage, not intent. You still need timezone-aware display and recurrence logic.”
“What if the meeting was entered in Sao Paulo before a DST rule change?”

Verification signal

Certificates capture the level you demonstrated

Each credential includes the skill, level, verification code, and the evidence-backed claims attached to that result.

Example credential

A certificate someone can check at a glance.

Verification link, credential code, assessed areas, and signed record in one view.

Verified record

Status, issuer, and date are visible without opening the full session.

Direct verify link

Scan or open the public verification page from the credential itself.

Assessed areas

The credential names what was actually examined, not just a generic pass.

Signed payload

The record carries a signature block for verification and storage.

The loop

One skill. One conversation. One clear result.

Start immediately, complete the assessment, review the result, and issue a certificate at the end if you want that credential on record.

01 · Pick skill

Choose a skill and begin

Pick a focused subject from the catalog and move straight into the conversation. No account is needed.

02 · Talk it through

Take a live conversational exam

The AI colleague calibrates to your level, pushes back, and tests how well you explain and defend your thinking.

03 · Grade evidence

Separate rubric model evaluates the transcript

Dimensions, errors, strengths, and misconceptions are scored independently from the conversation itself.

04 · Issue certificate

Pay only if you want the credential

You can finish the assessment first. Certificate issuance happens at the end, once you decide to put the result on record.

Wallet

Build a certificate set that supports your professional training.

  • Keep completed credentials in one place instead of scattering links across programs and roles.
  • Show progression across adjacent skills, not just one isolated exam result.
  • Use the wallet as a shareable record for schools, employers, and training partners.
  • Turn individual certificates into a broader profile of demonstrated capability.
