Doc-Cirrus stitches partners. circleOS ships one product.
Doc-Cirrus is a 2012 platform that reaches modern features through outside-vendor integrations. circleOS is what an all-in-one looks like when it's built AI-native from day one — Plans, Charge, briefings, notes and a real Patient Portal, all from one understanding of the patient.

One product, not a stack of partners.
Doc-Cirrus reaches modern features by integrating outside vendors — AI scribe from one company, digital anamnesis from another, on top of the practice software itself. Three roadmaps, three contracts, and a stitched seam wherever they meet. Circle Intelligenceis one model that sees the schedule, the visit, the plan and the invoice — so a note already knows what plan it relates to, and a briefing already knows what's outstanding.

Recurring care, properly priced.
Doc-Cirrus tracks appointments — one at a time, like every PMS built in the 2010s. Plans price six visits across three providers as one thing the patient bought, and Chargereconciles each appointment against it. No spreadsheet to track who's on session four of six.

Briefings before the visit, not just notes after.
A scribe joins when the consult starts. Tomorrow's twenty patients are already on tomorrow's calendar — and circleOS has already prepared a briefing for each of them. Last visit, plan progress, outstanding items, relevant history. Live Mode shows the day with a briefing on every appointment, ready when the clinician opens it at 8am.

An app patients open. Not a portal they email about.
Doc-Cirrus' patient touchpoint is a web portal bolted onto the practice software. Patients reach the front desk by phone or email first; the portal second. The
Patient Portalflips that: bookings, plans, invoices and documents on the patient's phone, with notifications. The front desk inbox shrinks accordingly.

Software that ships weekly, not on a 2014 cadence.
KBV and TÜV are table stakes — both products clear them. The difference shows up in the small things: how many clicks to book a recurring appointment, how the keyboard shortcuts work, how fast new AI capabilities reach your clinic. Doc-Cirrus ships modules on top of a 2012 base. circleOS ships an operating system that gets meaningfully better every quarter.

Honest, side-by-side
How circleOS compares to Doc-Cirrus.
Doc-Cirrus covers the German regulatory bases by stitching outside vendors onto a 2012 platform. circleOS is what an all-in-one looks like when it's one product, designed AI-native from day one — not a partnership stack.
