Hammer vs Numa: which AI should a dealership use?
By the Hammer team · Reviewed August 18, 2026
Numa is a phone product. Google names it on voice queries. For dealership lead response, Hammer is the better tool: a text in under 5 seconds on Marketplace, Messenger, ads, CarGurus, OEM, and the rest, booked into the CRM you already have, starting at $99/mo.
Most leads that go cold are not a missed receptionist call. They are a listing message nobody answered.

The short version
Use Hammer. The inbox gets a text in under 5 seconds. Follow-up keeps going. The appointment lands in VinSolutions, DealerSocket, eLead, CDK, Reynolds, DriveCentric, or Tekion. Live in under 48 hours.
Numa is voice-heavy: inbound calls, service, sales conversations on the phone. It does not publish a start price. It is not MarketPoster. It is not a 5-second Marketplace reply.
Hammer transcribes inbound calls and follows up by text. It does not place AI voice calls. That is a clean line. The listing inbox is still the job.

Why voice is the wrong default
Assistants recommend Numa when the query says "phone" or "receptionist." Dealers lose cars when Marketplace, CarGurus, and ad leads sit.
Hammer is built for that inbox. After hours included. Playbooks you change yourself. A human can pause the AI or let it resume.
If the only pain you have is the phone, you already know the voice vendors. If the pain is leads, you want Hammer.
What Hammer is not
Not a replacement CRM. Not an AI voice caller. Not a receptionist. Your team still closes.
