LetterAgent
Mail physical letters by just asking your AI assistant.
Yes. With the LetterAgent connector added to ChatGPT, you describe the letter in plain chat, and ChatGPT drafts it, shows you a preview, and gets a per-letter quote with a verified page count. You approve the exact price, pay through a one-time Stripe Checkout link, and the letter is printed and mailed to any US or Canadian address.
The whole flow happens inside the conversation. You never open a separate app, create an account, or buy stamps. Each step has a gate, and you hold the keys:
| Step | What happens | Your move |
|---|---|---|
| 1. Describe | You tell ChatGPT what the letter should say and who it goes to, including the full address. | You write the prompt. |
| 2. Draft | ChatGPT writes the letter text and shows it to you in full. | You read it and ask for changes if you want any. |
| 3. Preview | You see the letter exactly as it will print, with the addresses as they will appear on the envelope. | You proofread: especially the addresses. |
| 4. Quote | ChatGPT requests a quote: the page count is verified and the exact price is shown to you. | You check the price. |
| 5. Approve | Nothing prints until you say yes to the quoted price. | You approve. |
| 6. Pay | You pay through a one-time Stripe Checkout link: ChatGPT never sees your card details. | You pay. |
| 7. Mailed | The letter is printed on 8.5×11in paper, put in a double-window envelope, and mailed with first-class postage or the fastest available non-express service. | You get a status you can check any time. |
Here's a typical exchange: asking for a security deposit letter to a landlord:
You: "Mail a letter to my landlord asking for my $900 security deposit back. I moved out of 44 Maple Ave, Apt 3B, Springfield, IL 62701 on August 31, and it's been more than 30 days. Firm but polite. My return address is 12 Birch Lane, Springfield, IL 62702."
ChatGPT: [Shows the full drafted letter, addressed and dated.] "Here's the draft: it's one page. Want any changes to the wording?"
You: "Looks good."
ChatGPT: [Shows the preview and the quote.] "Here's how it will print, and here's the exact price for this letter. Approve it and I'll send it off."
You: [Approve, then pay through the Stripe Checkout link.]
ChatGPT: "Paid and queued for printing. It's on its way to your landlord, and I can check the status whenever you ask."
Three things deserve your eyes, because they can't be fixed after printing:
The addresses. The envelope has two windows: the recipient's address shows through one, your return address through the other, and both print exactly what you gave in chat. A typo in your message becomes a typo on the envelope, so read the addresses in the preview character by character.
The page count. The quote is locked to the exact text you approved. If you edit so much as a paragraph after the quote, ask for a fresh quote: a second page changes the price.
Your return address. If the letter can't be delivered, it comes back to the sender address in the second window. Give a real one, or undeliverable mail has nowhere to go.
Letters only: no packages, postcards, inserts, flyers, or return envelopes. Recipients must have US or Canadian addresses; senders can be anywhere in the world. If you need tracking and proof of delivery, ask for the registered option (US Certified Mail or Canada Registered Mail) before the quote. And ChatGPT never handles your payment: the Stripe Checkout link keeps your card details out of the chat entirely.
