Or ask your AI to send it

Ask Claude, or any assistant that supports MCP connectors, to make the card for you. Connect postcards.lol once and say “send Grandma a card about the tomatoes”. It writes the message, draws the front and shows you the card.

You always see the card first and pay yourself, through a checkout link. The assistant can’t charge you.

Questions

What does the postcard look like?

A 4×6 inch card on thick stock. Your photo or picture fills the front. The back has your message, an optional sign-off and the address.

Can I use my own photo?

Yes. Upload a JPEG, PNG or iPhone photo and crop it in the browser. Photos stay private and are only used to print your card.

How does “AI writes it” work?

Give a short brief, like “thank Aunt Jo for the birthday socks”. AI drafts the message and you can edit it before you pay. Every card is checked before it is mailed.

Can I send a card from Claude or another AI assistant?

Yes. Add https://api.postcards.lol/mcp as a connector in Claude, or in any app that supports MCP, sign in, and ask for a card. You see the card and pay in your browser before anything is mailed.

Where can I send cards?

Anywhere in the United States for now.

How long does it take?

We print your card after it is checked. Sent by USPS First-Class Mail. Most cards arrive 3–5 business days after printing.

How do recurring cards work?

Choose monthly or weekly and write a prompt once. Each card gets a new message and picture. To change the prompt or cancel at any time, sign in with the email you paid with (we email you a sign-in link) and open Your cards.
