Can ChatGPT or Claude send a fax for me?

Yes, with the right setup. An AI assistant with the LetterAgent connector can send a fax for you: you describe the document, the assistant verifies the page count and gives you a per-fax quote, you approve the exact total and pay once, and the fax is sent to a US or Canadian number. Fax is currently in testing, so treat it as experimental for now.

The whole flow, in order:

What do you actually tell the AI?

The document (or its contents) and the fax number. If the fax needs a cover sheet, say so and give the details: recipient name, your contact info, subject. The assistant assembles the pages exactly as quoted: what you approve is what goes out. Be precise with the number: fax machines don't have an "are you sure?" step, and a wrong digit sends your document to a stranger.

What happens between your request and the fax going out?

StepWhat happensWhat you do
Page count verifiedThe assistant counts pages before quotingNothing: this protects you from surprise totals
QuoteExact total for the whole fax, quoted up frontReview it
ApprovalNothing sends without your sign-offApprove or change the request
PaymentOne-time Stripe paymentPay once: no account, no subscription
SendingThe fax goes to the US or Canadian numberAsk the assistant for status any time

Two details worth knowing. First, the assistant never sees your payment card: Stripe Checkout handles the payment directly. Second, the page count is verified before the quote, not after: a 12-page document can't quietly become a 12-page surprise on your bill.

Can ChatGPT or Claude fax from my existing fax account?

No: this is a separate send flow, not a login to an account you already have. The assistant can't sign into third-party fax accounts on your behalf. If you already have a virtual fax number for receiving, keep it: LetterAgent sends outbound faxes only, so the two complement each other instead of overlapping.

What are the limits?

US and Canadian fax numbers only: no international destinations. No inbound faxes. And the honest caveat: fax is currently in testing while activation completes, so don't use it for a deadline you can't afford to miss. For anything time-critical, confirm the fax landed with the recipient before relying on it.
