The value proposition
Every comparable product either reads the customer’s content in order to work, or produces an estimate.
That is not a feature gap. It is an architectural one, and it cannot be closed without them abandoning what they sell.
Why the combination is the invention
No internet is required to seal or to verify
No internet is required to seal or to verify. Pull the network cable and it works exactly the same, and you can prove that with any network monitor: it never sends a byte.
There is no payload
Nothing runs on our infrastructure. There is nothing on our side to breach, subpoena or read. A record carries fingerprints and what you declared, never the file’s words and never its name.
The work never leaves the machine
The file is fingerprinted on your own machine. Only the fingerprint is ever used. You cannot read the document back out of it.
Privilege has nothing to waive
Any competitor that reads the customer’s content is structurally excluded from privileged work. That is not a feature gap, it is an architectural one, and it cannot be closed without them abandoning what they sell.
A strong seal is no use if getting it meant handing your document to someone else. Once they have a copy, you cannot take it back.
A fair comparison
Four kinds of tool already exist. None of them does this.
The difference is not how strong the cryptography is. It is what happens to your work in the process, and whose decision gets signed.
| Where your work goes | What it establishes | Who signs the human decision | Who can check it | |
|---|---|---|---|---|
 | Nowhere. Fingerprinted on your machine | What the person did, at the moment of work, sealed to the exact file | The person’s own key. The human is a signing party, not a field | Anyone. Free, offline, no account, forever |
| AI detectors | Uploaded and read. Seeing your content is how they work | An estimate about finished text, with a documented false-alarm rate | Nobody. There is no decision in it | Whoever pays for the same tool, and gets a different answer |
| Citation checkers | Uploaded to check the citations in it | That the cases you cited exist and say what you said | Nobody | You, inside the product |
| Cloud attestation | Evidence payloads processed and stored on their infrastructure | What the AI did | The reviewer is a field inside a record signed by the platform | A recipient, through their service |
| Online notarisation | The document is submitted to the platform | Who signed, bound to a verified legal identity | The platform signs | A recipient, through their service |
Categories, not a ranking. Each of these solves a real problem well. Online notarisation certifies identity, which is a different and useful job.
Why the combination is the invention
The work never leaves the machine
Only a fingerprint is used.
The human signs with their own key
As a party to the record, rather than appearing as a field inside a record signed by a platform.
Recipients verify free
Offline, with no account, and no contact with the issuer.
Composition is recorded at creation
Rather than estimated afterwards from finished text.
Periods with no record are themselves recorded
So silence is visible.
The limits are printed
On the face of every record.
The structural advantages
The structural advantages.
No marginal cost
Nothing runs on your infrastructure, so a customer costs nothing to serve.
Free verification is distribution
Every record sent to a client, a court or an opposing party puts the verifier in front of someone new, at no acquisition cost. The people most likely to need the product are exactly the people receiving records from someone who already has it.
No procurement
The buyer is the decision maker, the budget holder and the installer.
If the company stops
Every record already issued keeps verifying forever, free, with no dependency on the company, because the verifier is public and the key travels inside the record.
A model vendor cannot be its own referee
A model vendor cannot credibly be the neutral referee of its own output.
