II.Pricing

Where each plan unlocks the features you need

Most service businesses need three things from an AI receptionist: it answers, it books, it transfers. Here is what each plan actually includes.

PlanPriceCalendar bookingCall transfers
Rosie Professional$49/mo (250 min)No (text-a-link only)No
Rosie Scale$149/mo (1,000 min)YesYes
Rosie Growth$299/mo (2,000 min)YesYes
OnCallClerk entry$29/moYesYes

The honest comparison: if you only need a basic answering service that takes messages, Rosie Professional at $49/mo works. If you also need real appointment booking and call transfers, Rosie pushes you to $149/mo, while OnCallClerk includes both on the $29 plan.

IV.Honest take

When Rosie AI is the right pick

Rosie has clear strengths. Bilingual English and Spanish is included on the entry plan, which matters for businesses with a meaningful Spanish-speaking caller base. The native iOS and Android apps are well-built. The product has been around long enough to handle 2.8 million calls and counting.

If you need bilingual answering on day one and you do not need calendar booking or warm transfers, Rosie Professional at $49/month is reasonable. If you are an agency wanting to set up multiple clients, Rosie has an agency program worth a look.

Pick OnCallClerk if you want a lower entry price, you need appointment booking and call transfers without upgrading to the $149 tier, or you operate in a vertical where industry-specific configuration matters more than bilingual support.

V.FAQ

Frequently asked questions

What is Rosie AI and what does it do?

Rosie (heyrosie.com) is an AI answering service for small US businesses. It trains on your website and Google Business Profile, answers calls 24/7, takes messages, filters spam, and notifies you of new calls by text or email. Pricing starts at $49/month for the Professional plan with 250 included minutes. Calendar booking and call transfers require the Scale plan at $149/month.

How is OnCallClerk different from Rosie AI?

Two main differences. First, pricing: OnCallClerk starts at $29/month vs $49/month for Rosie. Second, what is included on the entry plan: Rosie gates appointment booking and call transfers behind the $149/month Scale plan, while OnCallClerk includes both on lower tiers. If you want calendar integration and the ability to transfer to a real person, you save meaningfully on OnCallClerk.

Is OnCallClerk cheaper than Rosie AI?

Yes, in two ways. The entry plan is $29/month vs Rosie at $49/month. And to unlock the same feature set most service businesses actually need (calendar booking and call transfers), Rosie pushes you to the Scale plan at $149/month. OnCallClerk includes those features at lower tiers, so the effective cost difference is larger than the headline numbers.

Does OnCallClerk train on my website like Rosie does?

Yes. You enter your business website, services, hours, and FAQs during onboarding and the AI agent answers callers using that information. You can also add custom instructions and exclusions for your specific industry, which is particularly useful for trades, junk removal, dental, legal, and other service verticals where Rosie applies a more general template.

Can I keep my existing business phone number?

Yes. OnCallClerk supports both port-in of your existing number and conditional call forwarding, the same approach Rosie uses. Your callers see no change. You set up forwarding once and the AI starts answering immediately.

Does OnCallClerk integrate with Google Calendar?

Yes. Calendar booking is included on standard plans, not gated behind a $149/month tier. The AI checks your live availability, offers open slots, and creates the event automatically. We also support Calendly-style booking links for businesses that prefer that flow.

Is the AI bilingual like Rosie offers?

Bilingual English and Spanish support is on our roadmap. Today, OnCallClerk operates in English with high-quality voices. If bilingual answering is critical from day one, Rosie offers it on Professional ($49/mo) and OnCallClerk may not be the right fit yet.

What industries does OnCallClerk specialise in?

OnCallClerk has pre-configured agents for plumbers, HVAC, electricians, general contractors, junk removal, locksmiths, towing, dental practices, medical clinics, law firms, real estate, restaurants, salons and spas, property management, and auto repair. Browse the full list at /industries.
