The plan

When the court is asking, get the instrument.

The attorney's receiptFor attorneys under an AI standing order. Your certification, declared and signed, with HumanMark's observed creation facts beside it. One monthly plan covers the ladder, $349 a month ($449 with human presence): the receipt, HumanMark, the Sealer, the verifier, and your judge-order pack, installed on your machine, working offline. Pay the year up front and you pay for ten months. Cancel whenever; what you have sealed stays yours. Your receipts are yours forever, and they verify free, forever, either way. One email starts it.
The engine, for organizationsEvery AI surface governed and proven. Licensed to your deployment. Starts with an introduction: tell us the problem and the AI behind it, and the scope comes back in writing before any call.

How buying works.

The free tools need nothing from you, not even an email address. For attorneys, the price is on the page: $349 a month, $449 with presence, a year for the price of ten months. One email starts it, and you have everything in writing before you pay. No account, no sales call unless you want one. For organizations, pricing is set to your deployment, by introduction. Either way, your receipts outlive any plan and verify free, forever.
