Assort Health vs Marisa.Care (2026)
Both put conversational agents in front of patients and they answer different questions with them. Assort builds specialty specific voice agents for the United States provider market, covering scheduling, intake, triage and routing, referrals, refills and document processing, with the specialty tuning as the argument. Marisa is built for Brazil and Mexico and does something structurally different: its agents start from a clinical gap found in the record, an assessment, a prescription, a diagnostic finding, then qualify and navigate the patient toward the care that gap implies, with revenue recapture as the stated outcome. That trigger layer is the more interesting design, and Marisa also publishes a right to request human review of an automated decision, which almost nothing in this index does. For a United States buyer, Assort is the practical answer and Marisa is the better idea.
- It orchestrates three layers rather than answering calls, with agents identifying clinical gaps from assessments, prescriptions and diagnostic findings, then qualifying and navigating patients toward the care those gaps imply.
- The data protection documentation is better than most records in this index, published as policy rather than asserted as compliance, including a stated right to request human review of an automated decision.
- It is built for markets most vendors in this index ignore, with deployments at reference hospitals in Brazil and Mexico under the regimes that actually govern there.
- Specialty specific voice agents rather than a general conversational layer, covering scheduling, intake, triage and routing, referrals, refills and document processing across the patient journey.
- It is deployed and compared across the United States provider market, where the record system integrations, health privacy expectations and staffing economics are the ones most buyers here are working with.
- The specialty tuning is the differentiator: a general agent that mishandles an orthopaedic referral or a dermatology intake creates work rather than removing it.

Side by Side
Each record in one paragraph
Written to be quoted whole. Each paragraph states what the AI Health Index verified about the vendor, with the caveats attached. Generated from this pair’s live capability grades, so it moves when a grade moves.
The AI Health Index awards Assort Health its top capability grade on AI Centrality, EHR and Interoperability Depth and Setting and Specialty Coverage. Set against Marisa.Care, Assort Health grades higher on several axes, including Autonomy and Oversight Model, Model and Technology Transparency and EHR and Interoperability Depth. Grades reflect evidence the AI Health Index could verify at the last review, so a low grade records disclosure the vendor has not published rather than a capability it has been shown to lack.

Questions buyers ask
Should we choose Assort Health or Marisa.Care?
On the axes where the AI Health Index separates them, Assort Health grades higher on several axes, including Autonomy and Oversight Model, Model and Technology Transparency and EHR and Interoperability Depth, and Marisa.Care grades higher on AI Liability and Recourse. Assort Health leads on the greater share of scored axes, but the split means the decision turns on which constraint is binding rather than on an overall winner.
Where do Assort Health and Marisa.Care differ most?
The widest separation the AI Health Index records between Assort Health and Marisa.Care is on Autonomy and Oversight Model, where Assort Health grades B and Marisa.Care grades C. That axis sits in the AI Capability group, so it should carry the most weight for a buyer whose binding constraint is how much of the work the model itself is trusted to do.
Where do Assort Health and Marisa.Care grade the same?
The AI Health Index grades Assort Health and Marisa.Care the same on several axes, including AI Centrality, Model Supply Chain Disclosure and Clinical and Operational Evidence. Neither holds an advantage the index can evidence on those axes, so they should not carry weight in a selection between these two.

The jurisdictional difference is the most important thing on this page and it is not a defect on either side: Marisa operates in Brazil and Mexico under those data protection and device regimes, so United States health privacy analysis does not apply to it, and a buyer outside Latin America is evaluating a product built for someone else's rules.
Both run autonomous agents on live patient conversations that book against a real schedule, and neither publishes a confidence threshold, an escalation rate or a bias evaluation. Neither publishes an independent attestation, and neither publishes pricing.
