Messaging Agents

AI agents that make phone calls for you

Some of these place or receive phone calls rather than only exchanging text. Voice is the most consequential thing one of these products does on your behalf, because a call cannot be unsent and the person on the other end usually does not know they are talking to software.

Agents that state this

Recorded only where the product's own public pages say so. One missing here may still do it and simply not mention it.

Agents compared by channel, how you start using them and pricing. Status is shown only where it is not live.

What the claim actually covers

The approaches split three ways. Boardy is voice-first: it phones you, learns what you are looking for, and makes introductions, which is the only product here where the call is the product rather than a feature. Wajo's agent calls businesses from its own number and pays with its own card. Duckbill routes the call to a human.

Several assistants add outbound calling to an otherwise text-based product, usually for the errands people least want to do: chasing a refund, sitting in a hold queue, booking a table that has no online option.

Worth checking before you enable it: whether the agent identifies itself as software, whether calls are recorded, and in which jurisdictions that recording is lawful. Of the 17 listings that call or can be called, 2 say on their own pages that the agent tells the person it is software, and 4 say whether the call is recorded; the rest say nothing, and each listing's table says which.

What these connect to

Named by the agents that state this capability. An agent that names none is not necessarily unconnected, it may simply not say.

Other jobs people hand over

Most of these agents do several of these, so the same product turns up under more than one.

Building one instead? The infrastructure side is a separate half of this site: every provider that carries these messages, what they charge, and what the headline price leaves out. The guides cover getting an agent into iMessage, WhatsApp and SMS.
