PaperAgent
Claude connectorCommunitySend real paper letters through USPS, with a PDF preview and exact price before anything is mailed.
PaperAgent lets Claude mail individual, one-off physical letters through the United States Postal Service.
Claude validates the US recipient address, writes a private draft, and shows you a PDF preview of exactly what will be printed along with the exact total. Nothing is sent until you approve: Claude then hands you a secure Stripe payment link, and once payment completes PaperAgent prints the letter in New York and hands it to USPS. You can ask Claude where a letter is at any time.
Good for cancellation notices, complaint and refund requests, landlord repair requests, security-deposit requests, and any letter that has to arrive on paper. Choose Standard First-Class mail, or Certified Mail with a USPS tracking number and a delivery record.
Checking prices and validating an address work without an account; drafting and sending need you to sign in.
PaperAgent is not an email, fax, bulk-mail, or legal-advice service. US domestic addresses only.
