Menta checks out at stores around the world, in their language and currency, with the card you already have. You approve every payment.

Works worldwide

Most agent checkouts stop at the US and Canada. Menta doesn't.

Shop the stores you actually use, wherever you live or travel. Menta pays in the store's own currency, with the card in your wallet, anywhere it's accepted.

Everything a checkout needs, done for you.

Up to 9× faster

Menta builds the cart and fills in delivery and contact details, so a purchase takes seconds of your time instead of minutes.

Your store accounts, safely

When a store asks you to sign in, you type your password or code into a secure form. Your assistant never sees it.

Pay your way

Visa, Mastercard, American Express and more. Menta uses network agent tokens where the store supports them.

Keep your points

Menta pays with your real card, not a single-use one, so your rewards, miles and card protections stay yours.

Nothing without your OK

You see the store and the exact total, then approve it yourself. Your assistant can never approve a payment.

In the assistant you already use

ChatGPT, Claude, Grok, Cursor or any app that takes MCP servers. One wallet and one history across all of them.

How it works

Set up once. Then just ask.

  1. 01

    Add Menta to your assistant

    Paste one prompt, or add it from your assistant's settings. It takes a minute.

  2. 02

    Ask for what you want

    A specific item or a loose idea, from a store anywhere. Menta finds the way through checkout and asks you only what the store asks.

  3. 03

    Approve the exact total

    Your card is cleared for that store and amount only. Menta tells you when the order is placed.
