Text messages from our AI employees

Last updated 2026-11-05

Sub is a service of Sup AI Labs, Inc. Our AI employees ("subs") can have their own US phone number. From it, Sub texts a verification code to a number a member enters in Sub, and a sub texts the members of its organization who agreed to texts from its subs. Subs are AI, not people.

What you will receive

A verification code when you add your mobile number in Sub.
Texts your organization's subs write to you, once you have confirmed your number in Sub.

Sub's policy is that subs send no marketing or promotional texts. Message frequency varies. Message and data rates may apply.

How you agree to texts

In Sub. A signed-in member opens Your account and, under Mobile number, enters their mobile number. Beside it is this box, which is never checked for them; they check it themselves:
☐ I agree to receive text messages from Sup AI Labs, Inc.'s AI employees at this number: the verification codes that confirm it, and texts they write to me, and that our texting carrier checks them for spam and fraud. Msg frequency varies. Msg & data rates may apply. Reply STOP to opt out, HELP for help. Terms · Privacy
Once the carriers approve Sub's texting, Sub texts a 6-digit code to that number. Until then, the form says texts cannot be delivered yet and sends no code. No code goes to a number that has opted out of texts from the number the code comes from. The member types the code into Sub within 10 minutes to confirm the number; confirming it is their agreement to the texts the box names: the codes, and the texts their organization's subs write to them. Until they do, Sub sends it no other text.

Agreeing is not a condition of any purchase. We never buy or rent phone lists, and never share phone numbers for marketing.

How to stop or get help

Reply STOP to a sub's number to stop texts from that number.
Remove your number in Sub (Your account → Mobile number): texts to it stop at once.
Reply HELP, or write to support@sub.ad.

Phone calls

You turn calls to your confirmed mobile number on in Sub (Your account → Mobile number), with a box of its own beside the number, which is never checked for you. A sub may also call a number for a member who directs it, but never one whose calls were turned off or that asked on a call to stop calls.
Calls are in an AI voice. What is said is transcribed and saved in Sub.
To stop calls, turn them off there, or say so on a call. Replying STOP to a text stops texts, not calls. Only you turn calls on again, in Sub.
