Smith.ai is the receptionist service most small businesses compare everything else against. It sells an AI Receptionist billed per call, and live receptionists billed per call with a long menu of per-call add-ons. Both work well. Both get expensive as your phone gets busier.

The quick answer: Carly is the best Smith.ai alternative for a business that wants every call answered, qualified and booked by the same rules, with texts and email in the same inbox. It answers when your team can’t, books callers on your team’s real calendars, texts from the same line and logs everything to your CRM. Copy one prompt into ChatGPT or Claude, grab a number, and you’re live. If you want a human on every call, Ruby and Posh are the closest live alternatives.

1. Carly

Carly is reliable and endlessly customizable: questions, booking rules and handoffs written once in plain English, applied the same way on every call.

  • Answers 24/7, or only when your team doesn’t pick up.
  • Qualifies and books on your team’s real Google and Outlook calendars, round robin, while the caller is on the line.
  • Speaks Spanish when the caller does, with no separate Spanish line.
  • Hands off to the right teammate through ring groups or a phone menu.
  • Calls new web leads within about a minute, then texts and emails if they miss it.
  • Texts from your business number: two-way texts, reminders, group texts and a text back on every missed call.
  • One team inbox and CRM. Transcripts, summaries, voicemails and texts, written back to HubSpot, Salesforce, Dynamics 365 or Carly’s own CRM.
  • Runs from ChatGPT or Claude with the Carly connector: build the agents, place calls and steer a live one from a chat (how it works).

Carly connects to thousands of apps, and anything after the call can run as a free Zapier-style workflow.

How to pick a Smith.ai alternative

  1. AI or humans? If a person must answer every call, compare Ruby and Posh. If you want calls answered and booked by rules you control, go with Carly.
  2. Price on last month’s call log. Per call (Smith.ai), per minute (Ruby, Posh, Dialzara), per caller (Goodcall) or by plan (Rosie, My AI Front Desk).
  3. Count the add-ons. Booking, notifications and Spanish are extras on Smith.ai’s live plans. Carly books, texts and speaks Spanish on every call.
  4. Test a handoff from your own phone before you switch.

See what people say

"Before Carly, I relied on a Calendly link, but the whole process felt impersonal and not very professional. Carly changed that by handling all the back-and-forth, so I'm no longer stuck in endless email threads trying to line up schedules.

Now Carly reaches out to candidates, shares my real-time availability, lets them pick a slot, then sends a Zoom link and drops it straight into my calendar. She sends reminders to both of us before each call, which has significantly reduced no-shows and last-minute confusion.

On top of scheduling, Carly acts like a full executive assistant, sending me my schedule the night before so I can prepare for each call. It reminds me of the old x.ai assistant, but Carly is noticeably smarter, faster, and better suited to my healthcare recruitment business."
