Short answer

How can I send physical checks using my AI?

You provide the payee and amount, and your agent triggers the printing and mailing via Lob. This moves the payment from your chat window into a physical mailbox. Here is the breakdown of how it works.

The results of a request.

Where your payments land.

When you instruct your agent to pay someone, these are the outcomes.

PRINTED

Physical check creation

The AI uses the tool to generate a real check. The data is sent to Lob for printing.

MAILED

Postage and delivery

Lob handles the envelope, the stamp, and the actual mailing. The check enters the postal system automatically.

TRACKED

Delivery status

You can ask your agent for updates on whether the check has arrived. The AI monitors the delivery progress.

HUMAN

Manual review needed

You must verify the recipient's address and the payment amount before the AI sends the command. The AI won't mail a check without your confirmation.

The workflow

What your AI does when the payment request arrives.

Your agent acts as the bridge between your conversation and the physical mail.

  1. Gather details

    Your agent identifies the payee, the amount, and the mailing address from your chat or connected data.

    create_check

  2. Generate check

    The agent sends the specific payment data to the printing service to create the document.

    create_check

  3. Trigger mailing

    Once the check is ready, the system prepares the envelope and handles the postage.

    create_check

  4. Confirm completion

    The agent tells you that the check is on its way and provides any relevant tracking info.

    create_check

FAQ

How this task behaves.

  • 01

    Can my AI send the check without me seeing it first?

    No. You should always review the payment details in your chat before confirming the action.

  • 02

    Does the AI handle the actual postage?

    Yes. The tool handles the printing, the envelope, and the postage through Lob.

  • 03

    Can the AI change the amount after the check is sent?

    No. Once the tool is triggered, the check is printed and mailed. You cannot edit a physical check through the AI.

  • 04

    Can my AI cancel a check that is already in the mail?

    No. The tool only handles the creation and mailing process. It does not have a tool to stop a check once it is processed.

  • 05

    What happens if the address is wrong?

    The AI will attempt to use the address you provide. If the address is invalid, the mail will fail through Lob, but the AI cannot fix physical mail errors automatically.
