Track progress

A live progress chart shows your SCI trajectory across all skills. Set goals and measure growth.

Three steps to a verified passport.

01

Claim your skills

Add the skills you know. Your passport starts with self-declared abilities — the foundation for everything that follows.

02

Earn proof

Complete peer sessions, pass AI assessments, and submit external evidence. Each activity creates an immutable record in your passport.

03

Share your passport

Send your verified passport to employers, clients, or collaborators. They see real proof, not self-reported claims.

Peer session completions
AI tutor assessments
Peer reviews and endorsements
External proofs and certificates

Four sources of proof.

Your passport accepts evidence from multiple sources. Each type contributes differently to your SCI score, creating a multi-dimensional view of your skill credibility.

Cryptographically signed

Every credential in your passport is backed by an immutable, tamper-proof event chain.

Portable anywhere

Share via link, embed on your site, or let companies verify through our API. No lock-in.

Growing with you

Your passport evolves with every session, assessment, and endorsement. Never static.
