Droxi vs MarianaAI (2026)
A narrow product with a stated boundary against a platform that claims almost everything. Droxi works the primary care inbox, reading each item against the patient's full record before proposing an action, running natively in the record system and saying plainly what it covers: three item types, one setting. MarianaAI offers more than twenty modules spanning documentation, coding, pre visit charting and inbox work with more than fifty claimed integrations, alongside figures that conflict with each other, claims built so they cannot be tested, and an autonomous coding module advertised as working with absolutely no human in the loop, with no threshold, abstention behaviour or escalation path published. Between a vendor that publishes a boundary and one that publishes superlatives, the boundary is worth more, because it is the only one of the two you can hold them to.
- It reads each inbound item against the patient's full record before proposing an action, with the boundary of what it will act on stated.
- It runs natively inside the record system with no separate login, listed on a major marketplace rather than only asserting integration.
- Scope is deliberately narrow and disclosed, primary care and three item types.
- Ambient documentation is one module among many, alongside autonomous coding, pre visit charting and inbox work, so one vendor covers more of the day.
- Breadth is asserted across more than fifty record system integrations naming the major platforms.
- For an organisation wanting a single platform across documentation, coding and inbox, the module count covers more of the estate.
This comparison is published by AI Health Index, an independent research platform that compares healthcare AI vendors objectively. Droxi and MarianaAI are each graded against the same capability taxonomy, from each vendor's own public materials and the regulatory record, under the AI Health Index verification standard.

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 Droxi its top capability grade on AI Centrality. Set against MarianaAI, Droxi grades higher on several axes, including Autonomy and Oversight Model, Model Supply Chain Disclosure and Clinical and Operational Evidence. 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 Droxi or MarianaAI?
On the axes where the AI Health Index separates them, Droxi grades higher on several axes, including Autonomy and Oversight Model, Model Supply Chain Disclosure and Clinical and Operational Evidence, and MarianaAI grades higher on Security Certifications and Trust Center. Droxi 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 Droxi and MarianaAI differ most?
The widest separation the AI Health Index records between Droxi and MarianaAI is on Autonomy and Oversight Model, where Droxi grades B and MarianaAI grades D. 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 Droxi and MarianaAI grade the same?
The AI Health Index grades Droxi and MarianaAI the same on several axes, including AI Centrality, Model and Technology Transparency and HIPAA and BAA Posture. Neither holds an advantage the index can evidence on those axes, so they should not carry weight in a selection between these two.
What have Droxi and MarianaAI not disclosed?
At the last review, at least one of Droxi and MarianaAI published thin or absent detail on Autonomy and Oversight Model, Model Supply Chain Disclosure and AI Governance and Bias Disclosure. The AI Health Index treats an absent disclosure as a gap in the public record rather than a failure of the product, so these are the axes to get in writing during diligence instead of inferring from the grade.

The disclosure quality between these is not close and it should decide the evaluation. MarianaAI's claims are largely superlative with several constructed so they cannot be tested, its published figures conflict with each other, and its commercial materials substitute return on investment claims for pricing. Its autonomous coding module is marketed as working with absolutely no human in the loop, with no threshold, no abstention behaviour and no escalation path published, on a function that produces claims submitted to payers. Its ambient documentation module does describe a review before notes sync to the record, so ask which module governs what you are buying.
Droxi publishes no model name, accuracy figure or subgroup analysis, and its only security claim is a compliance assertion rather than an attestation.
