How it works
Step 1
Share the recipient
Share a Contact card in the thread, or start your text with a TO: block:
TO: Ada Lovelace
1 Analysis Way
San Francisco, CA 94107Step 2
Add the letter
Write what the letter should say in plain language, in the same or a follow-up text.
Step 3
Confirm the quote
paperplane replies with the price. Nothing is printed or mailed until you reply to confirm that specific quote.
Not on Text/SMS? Any surface works.
The same three calls from the CLI, any MCP client or plain REST. Sandbox is free and mails nothing.

}Common questions

How much does it cost?
Letters start at $1.99 for First-Class; Certified Mail starts at $12.99. Every quote shows the exact total before you confirm anything.
