AI SDR
Also written: AI sales development representative, automated SDR
Quick answer
What is an AI SDR?
An AI SDR is software that performs sales development work: contacting prospects, asking qualifying questions, handling common objections and booking a meeting or handing over to a human. It differs from an AI receptionist in direction — an SDR works outbound lists, a receptionist answers inbound.
The category is muddled because four different products use overlapping names. The distinction that actually matters is direction and job.
| Term | Direction | Job |
|---|---|---|
| AI receptionist | Inbound | Answer, route, capture, book |
| AI appointment setter | Outbound | Book an existing warm contact |
| AI SDR | Outbound | Qualify a cold or semi-warm list, then hand over |
| AI voice agent | Either | The underlying capability, not a job |
An SDR is the only one of these expected to work a list where most contacts are not expecting the call, which is why it is the hardest to do well and the easiest to do badly.
What it can and cannot do
Reliable: consistent qualifying questions, immediate follow-up at any hour, accurate logging of every attempt and outcome, and never skipping the list because it looks unpromising.
Unreliable: anything requiring genuine discovery, negotiation, or a judgement call about whether a non-standard situation is worth pursuing. That is where a human should take the conversation.
The compliance part is not optional
Outbound calling and messaging is regulated, and an AI making the call changes nothing about that. In the US, the TCPA governs consent and the FCC has ruled that AI-generated voices in robocalls fall under existing restrictions. Several jurisdictions require disclosure that the caller is not human. Calling-time windows and do-not-call suppression apply exactly as they always did.
Confirm your obligations with your own advisor — this is not legal advice.

Services that use this
An AI SDR for the prospecting nobody has time to do
An AI SDR conducts outbound sales development — reaching prospects who have not enquired, opening the conversation, establishing whether there is a fit against your criteria, handling initial objections, and booking qualified meetings into your sales pipeline while logging the outcome in the CRM.
AI applied to lead capture, honestly scoped
AI improves lead generation by capturing enquiries across voice, chat and messaging at any hour, qualifying them conversationally rather than through long forms, enriching records with what was said, and routing by value — so more of the demand that already exists is captured and reaches the right person.
An AI appointment setter that works your list every day
An AI appointment setter places outbound calls automatically — triggered by a new lead arriving, or worked through an existing list. It opens the conversation, confirms interest, qualifies against your criteria, handles common objections, checks live calendar availability and books the appointment, writing the outcome back to the CRM.
