What do people ask most?

These are the questions we get most, answered from published vendor data.

Is Upfirst AI cheaper than Smith.ai?

Above very low volume, yes, at every volume we modelled. At the lowest volumes Smith.ai's free plan costs less. See the cost breakdown on this page.

How do the two bill?

Both bill per call. Smith.ai has a free plan, Pro and Enterprise tiers; Upfirst AI has Starter, Premium, Pro and Scale tiers. Both charge per extra call.

Do spam calls count?

Upfirst says spam, calls under 15 seconds and silent calls aren't billed. Smith.ai says known spammers are filtered before answering and lets you remove a share of calls each cycle as spam.

Does either offer a human receptionist?

Smith.ai's page mentions transferring complex calls to its live North America-based receptionists. Upfirst mentions warm transfers to you or your team, not a staffed agent network.

Is there a contract, and how do I cancel?

Smith.ai is month-to-month with 30 days' notice to cancel. Upfirst AI has a free trial and monthly or annual billing; we did not find cancellation terms on its pricing page.

Have you tested both?

Not yet. Test-call results are coming soon.
