Prove you're human. Now, and later.

Every year it gets harder to tell people from machines online. An account opened today, with a real check and years of honest history behind it, is something no bot can fake after the fact. Start yours now — we record how you signed up, tamper-evidently, and let you strengthen it as better checks arrive.

Humanhood (n.) — the standing a human holds by answering for an account. Earned over time, forfeited on abuse. Like knighthood: a conferred, revocable status — never a claim that what an account publishes is human-made.

Time is the moat

Attackers can buy devices and labor, but not a history that already happened.

Graded, not binary

We store the strength of each check, never a bare "human: yes."

Tamper-evident

Your provenance is a hash-chained record you'll be able to verify.
