Write for two minutes. See your proof.
This is the actual Humanums editor, capturing the actual behavioral signals, scored by the actual engine that issues certificates. Write a hundred words in it and you will get a real human confidence score broken down signal by signal. No account, no database, no certificate — just the thing itself, running.
Write about the last time you changed your mind.
What you used to think, what cracked it, and where you landed. A hundred words is enough — the point is that you compose it here rather than arrive with it finished.
Nothing here is saved. This demo produces a score, not a certificate — certificates come from a signed, verifiable record tied to an account.
Six behavioral signals, weighted.
Each signal is scored from 0 to 100 and combined into a weighted average. A signal with too little data is dropped and its weight redistributed, so a short piece is scored on what it actually has. A seventh check on vocabulary and character diversity screens out keyboard mashing before any of this runs.
- Keystroke cadence20%
- The coefficient of variation of the gaps between your keystrokes. Human typing accelerates through familiar words and stalls at hard ones; uniform timing is the signature of a script or a paste.
- Pause frequency15%
- How many pauses longer than two seconds you took, normalised per thousand words. Thinking leaves gaps, and composition leaves more of them than transcription does.
- Revision ratio15%
- The share of your edits that happened away from the end of the document — going back to rework a sentence you had already written. Linear, first-draft-final text scores low here.
- Paste ratio15%
- Characters pasted against characters typed. Some pasting is normal for quotes and links. A document that is mostly paste has no writing process to certify.
- Session distribution5%
- Whether the writing happened in one sitting or across several. This demo is always a single session, so the signal is present but carries little weight.
- Content over time10%
- Words per minute across your active writing time. Composition sits in a plausible band; sustained speeds well past it look like transcription rather than thinking.
What this demo is not.
It is not an AI detector. Nothing on this page reads your prose looking for machine-written style. That approach is why detectors flag human essays as AI-generated and clear AI text that has been lightly rewritten. Humanums never sees a reason to guess, because it watched the writing happen. If you want the contrast, the free AI detector on this site does the text-heuristic thing, and says plainly why it cannot be trusted.
It is not a certificate. A certificate is a signed record: your text hashed, the score fixed at a moment in time, a short code, a public verification page and an embeddable badge. That has to be attributable to someone, which is why it needs an account. What you get here is a number that lives in your browser tab.
It is not the full anti-fraud picture. Real certification also checks server-recorded save history: how many times the document was saved, over what wall-clock span, and whether the content grew gradually or appeared in one jump. A throwaway demo has no save history, so those checks are skipped here. Everything else — the timing entropy check, the skewness check, the pause-variability check, the keystroke-to-word ratio bounds — runs exactly as it does in production.
A low score is not an accusation. It means the writing process left too little evidence behind. That happens to people who compose in another app and paste, people who write a hundred words in twenty seconds because they already knew the sentence, and people who type so evenly that the cadence signal has nothing to work with. The honest answer in all three cases is the same: there is not enough here to certify.
About this demo.
Do I need an account to try this?
No. The demo runs without an account and without a login. You write in the editor, press the score button, and get the result. An account is only needed if you want to save your work and turn a score into a verifiable certificate.
Is this the same scoring engine the paid product uses?
Yes. The demo calls the same scoring code as the certification flow, with the same signal weights, the same thresholds and the same anti-fraud checks. The only difference is that a certification also verifies server-side save history, which a throwaway demo has none of.
Is my writing stored anywhere?
No. The demo buffers behavioral events in your browser, posts them once to a stateless scoring endpoint together with your text, and gets a score back. Nothing is written to a database, and the result disappears when you close the tab.
Why does the demo need 100 words and about a minute?
Below roughly 100 words and 50 keystroke events there isn't enough behavioral data for the signals to mean anything, and the scorer refuses to guess. A minute of writing activity is the minimum span the content-over-time signal needs. Those are the same minimums the real certification enforces.
What happens if I paste the text instead of typing it?
Your paste ratio collapses and, depending on how much you pasted, the score drops below the certification threshold or the scorer refuses outright. That is the intended behavior. Humanums measures how text arrived in the document, so text that arrived finished has nothing to certify.
Is this an AI detector?
No, and the difference matters. An AI detector reads finished text and estimates a probability, which is why detectors flag human writing as machine-written. Humanums never analyses your prose for AI-ness. It records how the writing happened and scores that process.
Can I fake the behavior with a typing script?
The scorer runs several checks aimed at exactly that: the distribution of your inter-key intervals has to be skewed the way human typing is, pause durations have to vary, keystroke counts have to be consistent with the word count, and timing that is too uniform is rejected. Certification adds server-recorded save history on top of that.
What is the difference between this score and a certificate?
The score is a number that exists only in your browser session. A certificate is a signed, dated record tied to the exact text you wrote, with a public verification page and an embeddable badge that anyone can check. Certificates require an account because they have to be attributable.
