License

An asset you own. Not a subscription you rent.

$70, once, for life. The license is an Engramm: inscribed on-chain on Base, held in your own wallet. It opens the reserved features, and the app we keep for licensees.

Transferable as simply as it's owned. What's an Engramm? →

Buying, inside the app

It all happens inside the OS.

The license and the cloud credits are bought inside Mnemosyne OS, from the wallet the app already holds for you. No address to copy, no form to fill in, no transaction hash to paste. The app knows where your license has to land. Download it, open the wallet, buy.

  1. 1

    Install Mnemosyne OS

    The personal edition is free and stays free. You are not buying the right to open the app, you are buying what the license unlocks.

    Download Mnemosyne OS

  2. 2

    Open the wallet, buy your license

    Your sovereign wallet is created on your machine at first launch. No account, no password. From it: $70 for the license, or cloud credits if you'd rather run models without plugging in your own API key. Card payment, handled by Stripe; your card details never pass through us.

  3. 3

    Activation is by hand, and that is deliberate

    Credits land in your wallet as soon as the payment clears. The license is minted by the founder, by hand, once the payment is confirmed. Count a few hours. Minting it automatically would mean a wallet able to issue Engramms living in a server variable: that's the one secret whose leak can't be undone. $70 once, for life. Not $720 over three years of a subscription that evaporates.

A question before buying, or a payment that went sideways? Write to us. The founder answers.

Reserved for licensees

An app that's only for you.

Every founder license will open an app reserved for licensees. It is in development, not a mockup. We are not showing it yet.
