About Arini
What Arini is
Arini is one of the most visible dental AI receptionists on the market, with strong real-time integration into the major dental practice-management systems and meaningful traction among DSOs. For a dental group whose buying decision turns on live PMS write-back, Arini is a serious and credible option.
Their pricing
Arini does not publish standard pricing publicly; deals are quoted per practice or per group, with DSO-oriented packaging. Checked September 2026.
Where they're strong
- • Deep, real-time write-back into Dentrix, Eaglesoft and Open Dental
- • Built exclusively for dental workflows and dental vocabulary
- • Strong DSO and multi-location traction
- • Well-funded and focused on a single vertical
Where they fall short
- • Dental only — no path if you also run a med spa, vet clinic or PT practice
- • Voice-first, so SMS is not an equal channel with shared context
- • No published pricing, which slows evaluation for a single practice
- • Packaging oriented toward groups rather than independent offices

Honest recommendation
Which one is right for you
Choose Arini if…
- • You are a dental group or DSO and live Dentrix or Eaglesoft write-back is the deciding factor
- • Dental is the only vertical you will ever operate in
- • You want a vendor whose entire roadmap is dental
Choose optni.ai if…
- • You want text to be a first-class channel, not an add-on
- • You run or plan to run more than one practice type
- • You want to see pricing before booking a sales call
- • You are an independent practice rather than a group
The verdict
Arini's dental focus is a real advantage, and for a DSO buying on live PMS integration they are a strong choice. optni.ai trades some of that dental-specific depth for omnichannel coverage, pricing transparency and a product that follows you if you add a med spa or a second practice type.
Questions
What people ask about this comparison
Yes — confirmed bookings write back to Open Dental, Dentrix, Eaglesoft and Curve Dental. Arini's integration is deeper and real-time; if that specific capability is your deciding factor, evaluate both directly.
Sometimes. A single-vertical product goes deeper on that vertical's software. The trade-off is channel coverage and flexibility — and for most independent practices, missed calls and unanswered texts are a bigger problem than write-back latency.
