Your AI chat

Make a birthday card for Sam, he turns 8. From all of us, please mail it.

A boy rides a friendly green dinosaur with balloons tied to its tail. The card says “Happy 8th Birthday, Sam!”.

Here is your card. $6.99, printed and mailed in the US.

The printed cards: Sam's birthday card in wax crayon, a boy riding a dinosaur; the open card with the greeting inside, “Dear Sam,”; an envelope; and the Millers' Christmas card behind.

Personal, not off the shelf: your names, your occasion, a message for each person.

Ask for a card in the AI chat you already use. We print a real folded card and mail it to each person in the US: one card, or the same card to up to 100 people.

1 sentence in your AI app

“Make a Christmas card for our friends, from the four of us.”

A family of four carries a small fir tree home through a snowy village street. The card says “Merry Christmas, the Johnsons”.

Done in a few minutes.

Inside: a personal greeting for every person

One card, one order: only the greeting changes for each person.

A folded Christmas card: the front shows the Miller family and their dog by the tree and the fireplace. The open card shows the printed greeting inside: “Dear Grandma Rosa,” a short message and “With love, the Millers”.
  • The inside of the card, starting “Dear Grandma Rosa,”.
  • The same inside, starting “Dear Linda,”.
  • The same inside, starting “Dear Tom and Kate,”.

How it works

Three steps in the chat that you already use. Here is an example.

  1. Describe

    Tell your AI app who the card is for: names, the occasion, a hobby, a place.

  2. Pick a draft

    We make picture drafts in the styles that your AI app proposes. It writes the message with you.

  3. Approve once

    Check the preview, each recipient and the full price. One approval, one payment. We print and mail.

An example. The names are made up.

Connect once. When you connect, you sign in once and enter your name and address. Your US address is the return address on each card.

One Christmas card to all your friends, from your question to the order.

We e-mail you when the post has your card. A card has no delivery record.

  1. You:

    Make our Christmas card for our friends. We are the Millers: the five of us and our dog. We always get our tree together.

  2. Agent Letter DeskRead the card optionsget_card_options

  3. AI:

    Merry Christmas to the Millers! I suggest 2 styles: a gouache picture-book scene by the tree, or a two-color linocut of a snowy street. Should the picture say “Merry Christmas from the Millers”?

  4. You:

    Show me both, with those words.

  5. Agent Letter DeskMake 3 picture draftscreate_card_picture

  6. AI:

    Here are 3 drafts: one in each style and one more idea. Each one shows the printed front. Which one do you like?

    1. Draft 1: A family of five and their golden retriever by the Christmas tree and the fireplace, painted in gouache. The card says “Merry Christmas, the Millers”.Draft 1
    2. Draft 2: The family walks down a snowy small-town street, carrying a fresh Christmas tree; the boy and the dog run ahead. The card says “Merry Christmas from the Millers”.Draft 2
    3. Draft 3: The family builds a big snowman in the front yard; the toddler puts on its hat, the dog wears a red scarf. The card says “Merry Christmas from the Millers”.Draft 3
  7. You:

    Number 2. Inside, wish them a merry Christmas and tell them about our year: a first tooth, a new puppy trick, too many cookies. Start each card with the first name. Here are our 12 friends with their addresses.

Questions

Questions about cards

Do I need a photo?

A photo is optional. Without one, we make the picture in the style you choose. You can use any photo that you have the right to use, for example of family or friends, with their OK. Your AI app gives you a link to upload it. The front can also show a short text instead of a picture.

Can I send a card to several people at once?

Yes. One card, one order, one approval, with a personal greeting for each person. $6.99 a card, $5.99 a card from 10 cards in one order, $5.49 a card from 25 cards. Separate orders are not added up.

Which AI apps can I use?

Claude, ChatGPT, Grok and Mistral Vibe. You connect your AI app once and sign in with Google or with a code by e-mail. Then you ask it for a card.

Can I change the picture or the text?

Yes. Ask your AI app for changes until you like the card. You see the preview and the full price before you approve. After that, you can cancel each card until its printing starts.

What if an address is wrong?

We check each address before you approve and tell you when something looks wrong. If the post cannot deliver a card because of a wrong address that you gave, we cannot refund it.

When does a card arrive?

We mail each card within 4 US business days after your order, 6 in the weeks before Christmas. Usually we mail it 1 business day after your order, 2 in the weeks before Christmas. USPS First-Class Mail usually takes 1–5 days. Your order page names both days: the day a card usually arrives, and the day it arrives at the latest.

Who sees my card?

We and our print partner, to check, print and mail it. Automatic checks read it first; the privacy policy has the details. We keep the picture, the message and the addresses only until your cards are with the post. Then we delete them. Privacy policy

Can I send a card outside the US?

Not yet. Greeting cards for Europe come by 2027 at the latest. Letters already go to Europe today. Letters in Europe
