For humans who create

A birth certificate for what you create.

Not a guess. Not a detector. A record, made at creation.

Put your mark on something you made, the moment you make it. A poem, a song, an idea, an agreement, a message that mattered. Today it works on the words you write, and it grows to cover voice, art, photography, film, and presence, proven live.

A specimen mark, with sample data. Tap it to watch again.

Like a birth certificate, it records who made something, and when. It is proof of authorship that you hold and anyone can check, not a certificate of compliance with anything.

The badge travels with the work, and anyone can check it, free.

It captures. It does not detect.

Every other tool guesses. It reads finished work, runs a model, and returns a probability that is sometimes right and sometimes wrong.

HumanMark is the opposite. It records the work as you make it, on your own device, and signs the result. A record issued at creation, and verifiable for as long as the work exists. It is built for the people detectors let down: teachers, publishers, and the evidentiary standards courts apply.

The hallmark. Stamped at creation. It travels with the work.

What it is, and what it isn't.

A signed record, issued the moment a piece is made.

You write inside HumanMark. It records how the work is made, and when you finish it issues a signed badge that travels with the work. Anyone can confirm it with the free verifier.

It is not a detector. It cannot score work it never watched being made. No after-the-fact guess, and no false alarm on writing that does not fit a model's idea of human.

From typing to signed badge.

1You create. Write inside HumanMark, in your browser. Your content never leaves your device.
2It watches. It records your authorship as the work is made, on your own device. Only a compact record leaves the device, never your content.
3It signs. When you finish, the work is signed and the badge issues. The signature travels with the work, and anyone can check it.
4You get the badge. Embed it anywhere the work appears. Anyone can verify it, free, in their own browser.

One number: how much of it was you.

One stroke, drawn while you watch. Hi 78 means the stroke closes 78 percent of the way. Hi 94 closes 94 percent. Score, animation, and badge are the same number. And every score reads in plain words too: Hi 78 is human-led, AI-assisted. How much of the work was you, made visible.

The HumanMark Index runs from 0 to 100, the share of human authorship it watched. 97 is almost entirely your hand. 78 is mostly yours, with some help, a research assist, a grammar fix. 50 and below means the machine did much of the work. It is a record of how the work was made, not a verdict. Editors and readers decide what counts as enough.

And every badge also reads in plain words, in the five bands filed in the patent: almost entirely human, human-led with AI assist, collaborative, AI-generated with light edits, machine. The number is the count it watched. The band is the attestation.

Wherever humans create.

One kernel, one mark, every medium. Anywhere there is a creation tool to connect to, the mark can be made there. The words you write carry the mark today. Every other surface is filed in the patent and goes live as each platform connects.

WritingJournalism, books, essays, legal drafting, email, the message that mattered. Live today.
MusicThe recording session and the composition, marked in the studio tools musicians already use.
Art & designBrush strokes and choices, marked in the drawing and design tools where the work is made.
Photography & filmThe camera, the cut, the edit trail. A film that can prove humans made it.
Voice & performanceA human speaking, live on a verified device. The answer to the cloned voice.
CodeThe engineer's hand in the commit, recorded as it is written.
Academic & researchThe citation trail and the writing itself, for students and scientists who need never be falsely accused.
HandwritingThe oldest mark of all, witnessed as it is made.

And it does not need the internet. The work is watched and the record is signed on your own device, and the badge checks offline, in any browser. A connection is needed to install, and only when the tool you create in lives online itself.

One badge per piece. One trajectory across every revision.

The Index marks a single piece of work. The Continuum tracks its authorship across every revision: each version signed, hash-chained, and independently verifiable. It reports how the human and AI mix changed from draft to draft, and it never stores your content, which is what protects attorney work product, peer-review drafts, and confidential authorship. The engine runs today, available to institutions now. Request the Continuum brief.

Checking is free. The write and the detailed read are licensed.

Checking a badgeFree, for anyone, forever. No account, no server. The open verifier confirms any badge in your own browser.
The writeLicensed. The right to author inside HumanMark and issue badges on the work: creators, and the publishers, schools, studios, and agencies behind them.
The detailed readLicensed. The right to integrate verification into a platform, re-display the badge at scale, and read the detailed record behind it: platforms, courts, insurers, and institutions.

The questions people ask first.

Does HumanMark detect AI?

No. It does not look at finished work and guess. It issues a record at the moment a piece is made, by watching it being made on your device. No badge does not mean the work is AI. It means HumanMark was not used.

What does the score mean?

The share of deliberate human authorship it watched. 97 means almost the entire piece came from your hand. 78 means mostly yours with some AI help. 50 and below means the machine produced much of it. The score is a record, not a verdict. Editors and readers decide what counts as enough.

Can I mark something I already wrote?

No. It can only record what it watched being made. Write or record your next piece inside HumanMark from the start. That is the choice that avoids the false alarms every retrospective detector suffers.

Does it see what I write?

No. Your content never leaves your device. It records your authorship locally, and only a compact record is sent to issue the signature. The work is yours. The proof is portable.

How is the author attested?

On the author's own device, with the same fingerprint or face unlock the device already uses. The biometric never leaves the device and is never stored by HumanMark. What travels is the signed statement that a live, attested person was present when the work was made. This tiered liveness attestation is filed in the patent.

How does a reader confirm a badge?

Every badge links to a free verifier that runs in the browser. It takes the badge and the content and returns valid or invalid. No HumanMark server is involved. The cryptography is the only thing that confirms it.

How does this fit the EU AI Act?

Article 50 enforcement begins August 2, 2026, with penalties up to fifteen million euros or three percent of global turnover, and its human-editorial-control exemption turns on demonstrable provenance. HumanMark produces the auditable, per-piece provenance record that the exemption asks for. The same logic serves the NIST AI framework and the U.S. state provenance laws.

Made by a human. Provable by anyone.
