Agentis vs Arini: AI Dental Receptionist Comparison 2026

Arini is probably the most credible competitor we have in the dental-specific AI receptionist space. They're Y Combinator backed, they've raised serious money, and unlike most AI receptionist companies, they picked dental as their wedge and committed to it.

So if you're evaluating AI receptionists for your dental practice and you've narrowed it to Agentis vs Arini, you're in the right tier of tools. Here's an honest breakdown.

The short version

Choose Arini if: your practice's entire workflow revolves around deep Dentrix or Open Dental integration, and you need the AI to natively read/write PMS records for complex schedule ops.

Choose Agentis if: you want flat-rate unlimited pricing, bilingual English/Spanish by default, faster time-to-live, and you're happy with calendar-based booking that syncs back to your PMS rather than live PMS writes for every call.

What Arini is

Arini is a dental-specific AI receptionist with a strong focus on practice management system (PMS) integration depth. Their pitch — and it's a legitimate one — is that a dental AI receptionist should read and write directly into your Dentrix, Open Dental, or Eaglesoft database as a first-class feature.

This means an Arini call can, in theory:

• Look up the caller by phone number in your PMS
• Check the provider's specific schedule for openings
• Book directly into the PMS slot
• Update patient records

That's the strongest version of what's possible. In practice, PMS integrations are messier than anyone advertises, but Arini has invested more engineering into this than most of the field.

What Agentis is

Agentis is a bilingual AI receptionist built for dental practices, med spas, and service businesses. Our voice agent Marcus handles inbound calls end-to-end — greeting, qualification, FAQs, appointment booking, emergency routing.

Our integration philosophy is different from Arini's: instead of writing directly into the PMS, we book into a calendar layer (Google Calendar, or a compatible booking backend) that then syncs to the PMS. This is less "clever" technically, but it's more reliable and dramatically faster to set up.

Head-to-head comparison

| Feature | Arini | Agentis | |---|---|---| | Industry focus | Dental (dedicated) | Dental, med spa, contractors | | Pricing model | Custom, typically $400+/mo | $199 flat / $399 pro / $799 enterprise | | Bilingual EN/ES | Available | Included by default | | PMS integration depth | Strong (Dentrix, Open Dental) | Calendar layer, PMS sync | | Setup time | 1–3 weeks | 24–48 hours | | 24/7 coverage | Yes | Yes | | HIPAA posture | BAA available | BAA available | | YC backing / track record | YC, strong funding | Founder-funded, smaller | | Voice quality | Strong | Strong | | Flat-rate unlimited | Varies by plan | Yes, all plans |

Where Arini genuinely wins

Let me just say the true things first.

1. PMS integration depth. If your staff's day looks like "open Dentrix, look at the schedule in Dentrix, block off Dentrix, recall patients from Dentrix," and you want the AI receptionist to do those same things inside Dentrix — Arini's architecture is better suited to that than ours is today.

2. Dental-only focus. Arini isn't building a generalist tool. Every feature decision is a dental decision. We're dental-first too, but we also serve med spa and contractor verticals. If you want the team whose entire roadmap is "make dental offices happier," Arini earns that claim.

3. Funding runway. They're a YC company with funded runway. That matters to practices who care about betting on a vendor that'll be around in five years. We're profitable and founder-funded, which is a different kind of sustainability bet.

Where Agentis wins

1. Bilingual is default, not upsell. Spanish-speaking patients aren't a specialty feature for a Miami, Los Angeles, Houston, or Phoenix practice — they're 30–60% of your call volume. Marcus handles Spanish natively on every plan, no extra charge, no configuration.

2. Flat pricing. $199/mo for unlimited calls on Essentials. Arini's pricing is typically bespoke and starts higher. For a solo practice or small group, the math strongly favors us.

3. Faster setup. We can go live in 24–48 hours. Arini's deeper PMS integration means 1–3 week setup, which isn't unreasonable but is a real cost.

4. Simpler failure mode. When a PMS integration breaks (and they all break, sometimes), a calendar-based system degrades to "book a call slot, front desk confirms in the PMS later." A PMS-native system either works or it dropped the booking. Our architecture is less ambitious but more resilient.

5. Works for multi-vertical owners. If you own a dental practice AND a med spa (more common than you'd think), Agentis covers both under one tool. Arini doesn't try to serve the med spa side.

The PMS question — is it actually a dealbreaker?

This is the question most practices get stuck on. Let me give you the honest frame.

If your current workflow is: Front desk uses Dentrix all day, they book all appointments directly in Dentrix, patients expect to be recognized by phone number and given their familiar provider's next available slot — and you believe your AI receptionist should replicate that exactly on day one — then PMS integration depth is load-bearing for you, and Arini's architecture fits better.

If your current workflow is: You get a lot of after-hours and overflow calls, patients mostly just want to book "next available cleaning" or "earliest emergency slot," and a front desk human will confirm/adjust PMS entries the next morning — then calendar-layer booking covers 95% of the value at 24–48 hour setup time and flat pricing.

Most of the practices we talk to fall into the second bucket. Some genuinely fall into the first, and we tell them to look at Arini.

What we're closing

We'll say this plainly: deeper Dentrix/Open Dental integration is our 2026 roadmap priority. The gap will get smaller. Today, if it's your #1 requirement, Arini is a better choice than us. By late 2026, that's a coin flip.

Try both

The best advice: call both demo numbers, do both trials, and see which one actually sounds right on a call your patients would make.
