LetterAgent
Mail physical letters by just asking your AI assistant.
You have four real options: have a mailing service print and mail the letter for you (no printer involved at any step), print at a public library or office-supply store, handwrite it, or use a printer at work. They differ in cost, effort, and how professional the result looks: here's how to pick.
| Option | What you need | Cost | Best when |
|---|---|---|---|
| AI mailing service (LetterAgent) | Just your words, in a chat with your AI assistant | Quoted up front, per letter: print, postage, and service fee included | You want zero errands: it's printed, enveloped, and posted for you |
| Library or office-store printing | The letter as a file on your phone or a USB drive, plus a few minutes | A small per-page fee | You need the paper copy in your hands today |
| Handwriting | Pen and paper | Essentially free | It's a personal letter, where handwriting is a feature, not a flaw |
| Workplace printer | Your employer's permission | Free | Your workplace tolerates occasional personal printing |
Yes: that's the entire point of LetterAgent. You describe the letter to your AI assistant (ChatGPT or Claude through the LetterAgent connector, or via the API), the assistant gives you a per-letter quote with the page count verified, you approve the exact price, and you pay once through Stripe Checkout. Then the letter is printed and mailed. No account, no signup, no subscription, and no printer at any step, yours or anyone else's. Recipients need a US or Canadian address; you as the sender can be anywhere in the world.
Nearly every public library has printers, usually for a small per-page fee. Here's the part most people miss: many libraries now offer wireless or mobile printing, so you can send the print job from your phone and just collect it at the desk: you never have to sit down at a library computer. Office-supply stores (Staples, FedEx Office, UPS Store locations) have self-serve printers, and staff can print from a USB drive or a file you email them. This route makes sense when you need the physical letter in your hands: for example, to add something to the envelope yourself or to hand-deliver it.
For personal letters (thank-you notes, condolences, letters to family), handwriting is not just okay, it's often nicer. For anything formal (a cancellation, a demand letter, correspondence with a company or landlord), typed reads as more credible and is easier for the recipient to scan and file. Two practical tips if you handwrite the envelope: print the address in block capitals rather than cursive, and use dark ink on plain white paper. Automated sorting equipment reads machine-printed addresses most reliably, block capitals second, and cursive last, so block capitals genuinely move your letter through the system faster with fewer mis-sorts.
Often, but check the policy first. Many workplaces tolerate occasional personal printing; some meter it, and some forbid it outright: don't assume. And don't print anything sensitive (medical, legal, or financial documents) on a shared office printer unless you're confident about the privacy setup. Print jobs can sit in queues and on output trays where anyone walking by can read them.
Match the method to the letter. Formal or time-sensitive letter and no printer at home? Have it printed and mailed for you: it's the only option with zero errands. Need the paper in hand, like for an enclosure or a hand delivery? Library or office-store printing. Personal note to someone you care about? Handwrite it; the effort is the point. Routine one-pager and a relaxed office policy? The work printer is fine.
