Which RingCentral AIR Alternative Is Best?

RingCentral AIR is strongest when RingCentral already runs your phones. This guide compares RingCentral AIR with Sera, Smith.ai, and Dialzara, and Sera starts at $49 a month with a 15-day trial.

The choice is simpler. Do you want the receptionist inside RingCentral, or a separate service for calls, texts, and website chats?

TL;DR: RingCentral fits current RingCentral customers. Sera is easy to test yourself. Smith.ai uses people, while Dialzara publishes plans based on call minutes.

Why Do People Look for RingCentral AI Receptionist Alternatives?

People look for RingCentral AI Receptionist alternatives when they are unsure about tying AI answering to their phone system. Others want a self-serve trial, public minute pricing, human receptionists, or one service that covers calls, texts, and website chats.

RingCentral says AI Receptionist answers calls around the clock, sends texts, books appointments, and collects lead details. It can learn from your website and uploaded documents.

RingCentral also says AIR can send complex calls to your team with a call summary. Its pricing page lists AI Receptionist as an add-on to RingEX plans.

RingEX Core is listed at $20 per user per month when paid annually. Advanced is $25, and Ultra is $35.

That may be a good fit. It may not be the best fit if you want to test an AI receptionist before changing anything about your phone account.

If AI receptionists are new to you, first read how an AI front desk works. Then compare the companies.

When I listen to test calls, I check transfers and unknown questions before I judge the voice. A pleasant voice helps, but the hard part is knowing when not to answer.

Use five questions before buying:

• Does it answer when your staff cannot?
• Does it know when to call a person?
• Can it book the right kind of appointment?
• Can you read the transcript afterward?
• Can you test it without a long project?

How Do the Main Options Compare?

The main options differ by who answers, how pricing is built, and how much you can test yourself. RingCentral keeps AIR close to the phone account, Sera focuses on a quick trial, Smith.ai uses people, and Dialzara publishes AI plans based on call minutes.

Option	Best for	Published pricing	Biggest limit
RingCentral AI Receptionist	Current RingCentral customers	Add-on to RingEX plans	Exact total depends on your RingCentral setup
Sera by Twig	Quick self-serve trial	Starts at $49 per month	Not HIPAA compliant
Smith.ai Virtual Front Desk	Human receptionists	Starts at $300 per month for 30 calls	Overage is per call
Dialzara voice plans	AI voice with minute buckets	Starts at $29 per month for 60 minutes	Overage is per minute
Dialzara text and website chat	Text or site chat gaps	SMS starts at $19 per month, chat at $39 standalone	Not a full phone answerer by itself

Here is the test I would run before moving your main number.

Test call	What to say	Passes if
New lead	“I need a quote for next Tuesday.”	It gets the service, time, and contact details
Existing customer	“I need to change my appointment.”	It knows whether to book or call staff
Angry caller	“Nobody called me back.”	It stays calm and gets a person involved
Bad fit	“Do you service an area 80 miles away?”	It follows your service-area rule
Unknown question	“Can you guarantee the final price?”	It does not invent an answer

Test unknown questions because a confident wrong answer can cost more than a missed call.

RingCentral AIR: Best if RingCentral Runs Your Phones

RingCentral AIR is a sensible first test if RingCentral already runs your phones. It answers calls and texts, books appointments, and uses your website or documents to answer common questions.

Best for: businesses already using RingCentral, especially if the owner wants phone service and AI answering in one account.

Pricing: RingCentral’s pricing page lists AIR as an add-on. It also lists RingEX Core at $20 per user per month, Advanced at $25, and Ultra at $35 when paid annually.

Limits: the final price can depend on your RingCentral plan and what else you buy. Ask RingCentral for your exact price before you compare it with another service.

I would pick RingCentral first when the business already likes RingCentral. That keeps your phone service and receptionist in one account.

I would slow down if the owner says, “I just want to test an AI receptionist this afternoon.” In that case, a product with self-serve signup may be cleaner.

Sera by Twig: Best for a Quick Trial

Sera fits businesses that want to sign up and test an AI receptionist without speaking with sales. Sera handles calls, texts, website chats, email, and WhatsApp, but booking, missed-call texts, live transfers, and multiple languages require the $499 Growth plan or higher.

Twig makes Sera. Sera is an AI receptionist: she answers every call, text and web chat 24/7, qualifies the caller, and books them with your team.

Best for: local service businesses that want one AI front desk across phone, SMS, web chat, email, and WhatsApp. It is also a good fit when an owner wants to test a live demo line first.

Pricing: Sera pricing starts at $49 per month on Starter. Every plan has a 15-day free trial with calls included. You can sign up without a credit card or sales call.

Setup: most businesses are live in under 30 minutes. You forward the phone line or add the website chat.

You can also call Sera’s live demo line at (650) 795-7838.

Limits: Sera is not HIPAA compliant and does not sign business associate agreements. Twig is SOC 2 Type II certified, but that is not the same as HIPAA compliance.

Your business decides when Sera should call a person. That person receives the conversation with the request.

Every conversation is logged with a full transcript.

For insurance agencies, Sera does not bind coverage, quote premiums, give coverage advice, or file claims with carriers. Licensed questions go to a person at the agency.

Sera also has no direct integration with agency management systems such as EZLynx, HawkSoft, Applied Epic, AMS360, or QQCatalyst.

My honest take: Sera is a strong option when you want quick setup for calls, texts, and website chats. It is not the right pick if you need HIPAA compliance or direct agency management system updates.

You can learn more on Sera’s homepage, or compare broader options in our guide to the best AI phone receptionist.

Smith.ai: Best if You Want People Answering

Smith.ai fits businesses that want real people answering calls around the clock. Its RingCentral page says you can connect RingCentral to Smith.ai for overflow, after-hours, weekends, vacations, and emergencies, with custom forwarding rules.

Best for: businesses where tone, judgment, and human warmth matter on most calls. Think legal services, high-ticket home services, or any business where each lead needs careful handling.

Pricing: Smith.ai starts at $300 a month for 30 calls. Its 90-call plan costs $810, and its 300-call plan costs $2,100.

Smith.ai’s pricing page lists overage fees of $11.50, $10.50, and $8.50 per call, depending on plan. It also says all plans include a 30-day money-back guarantee.

Limits: cost can rise if your call count jumps. Smith.ai’s listed human-staffed plans cost more than the listed entry plans from Sera and Dialzara.

I would choose Smith.ai over an AI-only system when the call quality bar is higher than the speed or price bar. I would not choose it just to answer simple hours, location, and booking questions.

Dialzara Voice Plans: Best for Minute Buckets

Dialzara fits owners who want plans with a set number of call minutes and a clear charge for extra minutes. Its pricing page lists AI voice plans with included minutes, overage rates, call summaries, and 24/7 availability.

Best for: buyers who know their call volume and average call length. If you can estimate monthly minutes, Dialzara’s plan structure is easy to model.

Pricing: Dialzara lists 60 minutes for $29 a month, 220 minutes for $99, and 500 minutes for $199.

Dialzara’s pricing page also lists overage rates of $0.48, $0.45, and $0.40 per minute on those plans. Its page says voice plans have no contract and can be canceled anytime.

Limits: minute pricing is clear, but you still need to watch usage. A busy season can push you above the included minutes.

Dialzara also prices outbound voice, SMS, and website chat separately. If you need calls, texts, and website chat, compare the full monthly price.

I would choose Dialzara when the owner wants public AI-only pricing and does not mind watching minutes. I would not choose it only because the entry plan is low.

Dialzara Text and Website Chat: Best if Calls Are Not the Only Gap

Dialzara also sells SMS and website chat products, which can make sense if your missed opportunities are not all phone calls. The fit is narrower than a full AI receptionist, but the pricing is public and useful for comparison.

Best for: businesses that already handle calls well but miss texts or website visitors. It can also help you see the cost of adding non-phone channels to a voice plan.

Pricing: Dialzara lists an AI SMS Agent at $19 per month plus $0.05 per AI message. It also lists an AI Website Chatbot at $39 per month as a standalone product.

Dialzara says website chat is free with voice plans, with 100 sessions per month included and $0.15 per extra session. Those details are listed on Dialzara’s pricing page.

Limits: text and chat do not replace phone answering. If your biggest problem is after-hours calls, start with voice first.

This option matters because many owners compare only the cheapest voice plan. The real bill can change when you add text, chat, booking, or staff alerts.

Which RingCentral AIR Alternative Should You Choose?

Choose RingCentral if it already runs your phones. Choose Sera for a trial you can start yourself, Smith.ai for human receptionists, or Dialzara for plans based on call minutes.

Need	Best pick	Why
Already on RingCentral	RingCentral AIR	It stays with the phone account you use
Fast test without sales call	Sera	15-day trial and self-serve signup
Human voice on most calls	Smith.ai	Live-staffed plans are the point
Public minute buckets	Dialzara voice plans	Plans show included minutes and overage
Text or website chat only	Dialzara text and chat	Public pricing for those channels
Almost no missed calls	Do nothing yet	Fix habits before buying another service

Doing nothing is still a real choice when missed calls are rare, low value, or already handled well by staff. Review one week of missed calls. If several could have become booked jobs, run a two-week test.

A simple next step is to read our plain-English guide on virtual receptionist pricing, then put a dollar value on one booked job.

If I owned a busy local service business, I would not spend a month comparing demos. I would pick two vendors and run the same 20-call test.

Use real calls from last week. New lead. Price question. Reschedule. Angry customer. Bad-fit caller. After-hours caller. Then read the transcripts.

Your winner is the one that gives fewer wrong answers, sends fewer calls to the wrong person, and gets more people booked without making your staff clean up a mess.

If you want to test Sera, start with Sera pricing or call the demo line at (650) 795-7838. If RingCentral already runs your phones, ask RingCentral what your exact add-on or bundle price would be before you compare it to anything else.
