circleOS vs. Eterno Cloud

circleOS vs. Eterno Cloud — the honest comparison.

Eterno is the closest direct comparison to circleOS in Germany — both are AI-native, all-in-one cloud platforms. The differences that matter for your clinic: stack-honest integrations, Plansas a first-class object, pre-visit briefings, and a Patient Portal that's your brand — not a polyclinic group's.

circleOS dashboard — appointments this week, latest bookings, latest comments

Built for any clinic. Not one group's polyclinics.

Eterno Cloud is the spinout of the ETERNO Group's own polyclinic operations — a software product extracted from one clinic group's playbook. The defaults reflect that playbook. circleOS was designed ground-up to fit whichever clinic group adopts it: your specialties, your locations, your roster, no inherited assumptions about how a day should run.

Stack honesty over a vertical bundle.

Stripe handles money. InSuite handles clinical billing. Fillout handles forms. circleOS is the layer that ties them to a patient. Each capability is best-of-breed — and replaceable when something better comes along. Eterno bundles its own version of every layer: one vendor, one set of trade-offs, no exit.

Plans, not packages.

The dental clinic that sells a six-visit aligner plan. The physio practice that sells a twelve-session rehab arc. The longevity clinic that sells a year of quarterly check-ins. Plans price those journeys up front and Charge reconciles each visit against the whole. Eterno tracks visits; circleOS tracks the thing the patient actually bought.

Pre-visit briefings, not just one-click documentation.

Eterno's AI runs insidethe visit — one-click documentation while the clinician consults. Useful, but it's only half the day. Circle Intelligence runs around it too: every patient on tomorrow's calendar gets a briefing before they walk in — last visit, plan progress, outstanding items, relevant context. The clinician arrives prepared.

Your name on the App Store icon.

The Patient Portalis your clinic's product — your domain, your brand, your patients managing their own bookings, plans, invoices and documents. Not a touchpoint inside another clinic group's experience. The patient's phone shows yourname, not a platform's.

Honest, side-by-side

How circleOS compares to Eterno Cloud.

Eterno is the closest direct comparison to circleOS in Germany. The honest difference: stack-honesty (Stripe/Fillout/InSuite vs vertical), Plans as a first-class object, and a Patient Portal that's a real app — not a checkout for one clinic group.
