Vera Health

Clinical evidence search engine for licensed clinicians, operated by Veracity-Health Inc. and free to verified clinicians and trainees with unlimited searches. The product is built on a retrieval first architecture that the company states is deliberately the reverse of generation first assistants: it searches a corpus given as more than 60 million peer reviewed papers, guidelines and care pathways, ranks what is relevant, applies evidence grading logic the company likens to the work of a guideline methodologist, then generates a short answer with inline citations tied to specific statements.

Alongside search it ships drug and interaction checking, a large calculator library, differential and treatment planning views, and specialty tailored literature updates, and it accrues continuing education credit per search, which is the second instance of that model in this category after UpToDate. In March 2026 the American College of Emergency Physicians announced a partnership placing ACEP clinical policies inside the product, confirmed on ACEP's own newsroom and quoted by ACEP president L. Anthony Cirillo.

Direction comes from a named international clinical council of sixteen physicians chaired by Scott M. Silvers, formerly chair of emergency medicine at Mayo Clinic and chief medical officer for knowledge management at Optum Health. Founded by Maxime Allouch and Taieb Bennani, both from MIT, and backed by Y Combinator and Gradient Ventures. Two scope notes carried on the record: every published performance figure is vendor run and no peer reviewed evaluation of the product was located, and the company publishes comparison content about other vendors on its own blog, so its characterisations of competitors are a self interested source.

Capability Axes

The short answer

Vera Health is a clinical evidence search engine for licensed clinicians, operated by Veracity-Health Inc. and offered free to verified clinicians and trainees with unlimited searches. Its architecture is deliberately retrieval first rather than generation first: it searches a corpus of peer reviewed papers, guidelines and care pathways, ranks what is relevant, applies evidence grading logic, then generates a short answer with inline citations tied to specific statements, which is the reverse of an assistant that writes an answer and looks for support afterwards. The AI Health Index grades it on the same fifteen capability axes it applies to every vendor: A on AI Centrality and A on HIPAA and BAA Posture are its strongest, while C on Clinical and Operational Evidence and C on EHR and Interoperability Depth are where a buyer should ask more. Verified as of Aug 2, 2026.

An AI Health Index grade measures what a buyer can verify from public sources on the date shown. It is not a rating of how good the product is. A vendor can build an excellent system and grade low on an axis because it publishes nothing an outsider can check. How grades read

AI Capability
AA on AI CentralityThe artificial intelligence is the product. Remove the model and there is nothing left to sell.
Vendor Published

The product is the model and the retrieval stack around it. Remove them and nothing saleable remains: there is no authored corpus of the company's own, no institutional workflow tooling and no device. What a user gets is the ability to ask 60 million documents a question in natural language and receive a synthesised answer, which is an act only a model performs.

The company also states its architecture as a positive design claim rather than as a label, describing a purpose built medical search engine that retrieves first, ranks, applies evidence grading logic and only then generates. That ordering is falsifiable in ordinary use, because a clinician can check whether the cited sources actually support the answer given. Most centrality claims in this index are not checkable that cheaply.

BB on Autonomy and Oversight ModelThe oversight structure is described and one part is missing, commonly the threshold at which the system stops or what happens after it is wrong.
Vendor Published

Adjunctive by design and by disclaimer. Every key statement is linked to its source so a clinician can read the underlying evidence and, in the company's own framing, document their reasoning. The application listing states plainly that the product supports clinical decision making and that the clinician should always apply their own judgement. The retrieval first ordering is itself an oversight mechanism, since it is meant to make the evidence checkable rather than to justify an answer after the fact.

Held at B on the question this index now puts to every generative clinical product, which UpToDate answered and this vendor has not. Nothing published states what the system does when the evidence is thin, absent or in conflict. There is no assumptions block naming what was taken for granted about the patient, no prompt asking the clinician to supply missing context, and no described abstention behaviour. Evidence grading logic is asserted but the rubric is not published, so a clinician cannot tell whether a weakly supported answer is visibly marked as one.

Ask directly what the product returns when the literature disagrees with itself, and whether the grade attached to a piece of evidence is surfaced to the reader or used only internally to rank.

BB on Model and Technology TransparencyThe approach or the suppliers are named without the version and update discipline behind them. Naming a supplier is the entry to this band both here and on Model Supply Chain Disclosure, which ask different questions of the same disclosure: who receives the data, and what produces the output.
Vendor Published

Mechanism is described in real terms rather than as marketing. The company publishes the sequence its product follows, states the corpus size and composition as peer reviewed papers, guidelines and care pathways, and positions the retrieval first ordering explicitly against generation first assistants while naming the failure that ordering is meant to prevent, which is that citations gathered after the fact can conceal an error.

Below that level it goes dark. No model class or model provider is named anywhere on the company's own material. The evidence grading logic is compared to the work of a guideline methodologist but no rubric, scale or worked example is published. The retrieval infrastructure is identified only through the supplier's own blog, not by the vendor.

The homepage carries a bar chart placing the product at 62.2 percent against three named foundation model vendors at 19.7, 21.3 and 37.3 percent, with no benchmark named on the chart, no methodology, no date and no link to a protocol. A vendor run comparison against named competitors, published without a method, is the weakest form of transparency, because it invites a comparison no reader can reproduce. Note also that this index has already recorded that the underlying dataset produced a wide spread of results across many models in the work that introduced it, so a single figure quoted out of that context tells a buyer very little.

CC on Model Supply Chain DisclosureThe architecture is described and no model provider is named. Naming a hosting provider alone does not lift a record out of this band. Record the host in the note, because it matters for residency and breach scope, and grade on the model layer, which is the question this axis is named for.
Vendor Published

One explicit commitment sits on this record and two counterweights come from the same policy. The commitment: personal data is stated not to be used to train the company's artificial intelligence systems, which is an explicit position rather than a silence, and a dedicated data minimisation section commits to processing only what is needed while naming encryption, access controls and anonymisation or pseudonymisation for data used in training. The counterweights are the vendor's own words.

Aggregated and de identified data covering physician access patterns, usage frequency and, stated explicitly, the inputs and outputs of the service may be used and shared with business partners and research organisations, so the questions a clinician asks and the answers they receive form a shareable derived asset even though their personal data does not train models.

And advertising partners are a named recipient category for device, network address, geolocation and analytics data, with the state specific section confirming those categories are shared with advertising networks for interest based advertising. Be precise about what that second point is: this is website and marketing analytics, not pharmaceutical advertising placed inside a clinical answer, which is a different and more consequential arrangement graded elsewhere in this segment.

It remains a clinician's professional interest data flowing to advertising networks, and a user of a product that costs nothing has a reasonable interest in knowing it. No model class or provider is named anywhere.

CC on Clinical and Operational EvidenceNamed customers, or vendor reported percentages with no method, denominator or reference standard. Scale of use is recorded here and is not treated as evidence of benefit.
Vendor Published

Every performance figure located is vendor generated and none is peer reviewed. The claims include a United States Medical Licensing Examination score of 97.5 percent, 84.9 percent on a New England Journal of Medicine question set and 62.2 percent on MedXpertQA, published through the company's own materials and through a blog written by one of its infrastructure suppliers, which is a source with a direct commercial interest in the result.

Two real third party relationships exist and neither is evidence of performance. The American College of Emergency Physicians partnership, confirmed on ACEP's own newsroom in March 2026 and quoted by its president, is a content licensing and distribution arrangement. The clinical council of sixteen named physicians is editorial and governance input. Both raise confidence in the process. Neither measures the output.

The grade records what a counterparty can verify today rather than a finding that the product performs poorly, and the company is young enough that an absence here is unsurprising. The comparison that matters is within the segment: OpenEvidence carries eleven independent evaluations including a systematic review, and Glass Health placed in an external physician validated safety benchmark it did not control. Submitting to an evaluation the vendor does not run is the single move that would change this grade.

BB on AI Safety and PHI StewardshipCategorical commitments are published, such as no training on customer data, without the retention schedule behind them.
Vendor Published

Two strong statements sit on the record. The privacy policy states that personal data is not used to train the company's artificial intelligence systems, which is an explicit commitment rather than a silence. A dedicated data minimisation section commits to processing only what is needed for the purpose and names encryption, access controls and anonymisation or pseudonymisation for data used in training.

Two counterweights hold it at B and both come from the vendor's own policy. Aggregated and de identified data covering physician access patterns, usage frequency and, stated explicitly, the inputs and outputs of the service, may be used and shared with business partners and research organisations. And advertising partners are a named recipient category for device, internet protocol, geolocation and web analytics data, with the California section confirming those categories are shared with advertising networks for interest based advertising.

Be precise about what that second point is and is not. This is website and marketing analytics, not pharmaceutical advertising placed inside a clinical answer, which is a different and more consequential arrangement graded elsewhere in this segment. It remains a clinician's professional interest data flowing to advertising networks, and someone using a product that costs nothing has a reasonable interest in knowing that.

Regulatory and Compliance
AA on HIPAA and BAA PostureBusiness associate status is stated, the agreement is available to read before contracting, the tier it applies at is clear, and the agreement discloses that it binds subcontractors who handle protected health information. Which parties those subcontractors are is graded on Model Supply Chain Disclosure and is not counted again here. Where any of the four cannot be verified from published material, the grade is the band below.
Vendor Published

The strongest position in this segment, and it rests on an artefact rather than an assertion. The full text of the business associate agreement is published at a public address, dated October 2025, and readable without contacting anyone. Nothing else graded in this category does that. The privacy policy carries a dedicated HIPAA section stating the company will enter a business associate agreement with a covered entity or its business associate on request, and a data protection officer is named with both an email address and a telephone number.

The instrument contains commitments a buyer would otherwise have to negotiate blind. Written notice of an impermissible use or disclosure, or of a security incident, within five business days. Breach notification no later than thirty calendar days. Reimbursement of the client's costs of complying with the breach notification rule where the breach was the vendor's. Subcontractor flow down of the same restrictions. Availability on request of the most recent independent HIPAA compliance report or HITRUST certification. And return or destruction of all protected health information on termination, extending to agents and subcontractors, with no copies retained.

One clause deserves a buyer's attention and is recorded here rather than left buried. All de identified information the vendor creates under the agreement is stated to belong exclusively to the vendor, with the client free to create its own separately. That is an ordinary commercial term and it is disclosed rather than hidden, but a covered entity signing it grants exclusive ownership of de identified derivatives of its own patient data, and it should be read before signature.

For scale within the segment: OpenEvidence offers a standard agreement that at least one health system could not reach acceptable terms on, Glass Health exposes acceptance inside its developer settings, Avo mentions HIPAA nowhere in its public legal documents, and UpToDate publishes nothing that could be retrieved.

BB on Security Certifications and Trust CenterA recognised certification is named in the vendor own material without the artefact, or with a scope or renewal question the buyer has to raise. A certification has a scope and a clock, and both are part of this grade.
Vendor Published

A public trust centre exists at a dedicated subdomain, run on a recognised trust centre platform, and the homepage carries four compliance marks: HIPAA, GDPR, SOC 2 and the National Institute of Standards and Technology artificial intelligence risk management framework. The SOC 2 mark specifies Type II. That is the single question this index puts to every SOC 2 claim and the one most vendors leave unanswered, so it is credited.

Held at B rather than A on what was not found. No penetration testing cadence, no vulnerability disclosure programme, no bug bounty and no security incident history were located, and independent review sites report that SOC 2 detail is gated behind an enterprise conversation rather than published. The peer that earned an A in this segment did so on an annual external penetration test plus a public vulnerability disclosure programme with a bounty, which is operational evidence rather than a badge.

Scope stated plainly, per the standing rule about grading unopened pages: the trust centre was confirmed to exist but its gated contents were not accessed, so what sits behind the request wall is unknown rather than absent.

CC on FDA and Regulatory StatusNo device claim is made and the product is scoped accordingly. Most administrative and operational products sit here and are not penalised for it, because this axis grades the appropriateness of the positioning rather than possession of a clearance.
Vendor Published

No clearance, no submission and no published regulatory positioning statement were located across the homepage, about page, privacy policy, terms and business associate agreement, all read in full.

The product has a reasonable argument for sitting outside device regulation and it is worth stating, because a buyer will ask. The clinical decision support exclusion turns on whether a clinician can independently review the basis of a recommendation, and a retrieval first product whose key statements each link to the source they came from sits closer to the centre of that exclusion than to its edge. Against that, the company describes itself in its own frequently asked questions as a clinical decision support search engine, and it ships differential diagnosis and treatment planning views alongside search. Generating a differential is a different act from reporting what the literature says, and it is the act that moves a product towards the line.

Graded C because the vendor has published no analysis of where it sits. Ask for the regulatory position on the differential and treatment planning features specifically rather than on the product as a whole.

BB on AI Governance and Bias DisclosureA governance framework with named process behind it, such as certification to an artificial intelligence management standard, or material written for a customer own review committee to evaluate the product with.
Vendor Published

More governance apparatus than most of this segment, and none of the measurement. On the apparatus side: alignment to the National Institute of Standards and Technology artificial intelligence risk management framework is claimed as a compliance mark, which is its first appearance in this category; a clinical council of sixteen named physicians with named institutions provides editorial direction; a data protection officer and a European Union representative are both named with contact details; and a data processing addendum is published alongside the privacy policy and terms.

On the measurement side there is nothing. No bias evaluation, no subgroup analysis by specialty, population or question type, no error taxonomy, no published accuracy floor and no external audit. The one comparative figure the company publishes is one it ran itself, against competitors, with no methodology attached.

The structural exposure that applies to every vendor in this category applies here with a particular twist. Grounding to a corpus inherits that corpus's blind spots as faithfully as its rigour, and this corpus is the published literature, whose known coverage gaps fall along the population lines a bias evaluation would test. A company claiming alignment to a risk management framework is better placed than most to publish what its own risk assessment found. Ask for that document by name.

CC on AI Liability and RecourseMechanisms exist that let someone challenge an output, such as audit trails, source traceability or review before commit, with nothing standing behind the output and no route for the harmed party.
Vendor Published

One disclosure here is genuinely good and one headline undercuts it. The good one: the company publishes the sequence its product follows, states the corpus size and composition, and positions its retrieval first ordering explicitly against generation first assistants while naming the failure that ordering is meant to prevent, which is that citations gathered after the fact can conceal an error.

Naming the specific failure your architecture exists to avoid is a form of limitation disclosure, because it tells a reader what to look for in competitors and, by implication, what would still go wrong here. The headline is the problem. A bar chart places the product at a stated percentage against three named foundation model vendors at lower ones, with no benchmark named on the chart, no methodology, no date and no link to a protocol.

A vendor run comparison against named competitors published without a method is the weakest form of transparency, because it invites a comparison no reader can reproduce and no competitor can answer, which is the opposite of the independent head to head evaluations this index credits elsewhere.

This index has also recorded that the underlying dataset produced a wide spread of results across many models in the work that introduced it, so a single figure quoted out of that context tells a buyer very little. No evidence grading rubric, scale or worked example is published either. Ask which benchmark, run when, under what protocol, and for the rubric.

Integration and Deployment
CC on EHR and Interoperability DepthIntegration is claimed through standards or a middleware layer with no system named and nothing to verify.
Vendor Published

No integration claim of any kind appears on the vendor's own material. The homepage, about page, privacy policy, terms and business associate agreement were read in full and none names an electronic health record, a marketplace listing, a Fast Healthcare Interoperability Resources conformance statement or a public application programming interface. Delivery is web and native mobile applications, and the product is used alongside the record rather than inside it.

The only integration claims located come from third party review directories, which report enterprise integrations with Epic, Cerner and MEDITECH under custom pricing, requiring technical coordination to deploy. Those sites are commercially motivated aggregators rather than the vendor, and this index does not grade on them.

The asymmetry is itself the finding and it is unusual. The failure this axis normally catches is a vendor overstating an integration it cannot deliver, and the index has graded exactly that elsewhere in this segment. Here the vendor states nothing while others state a great deal on its behalf. Establish directly what exists, in what form, and whether any customer is live on it.

BB on Deployment Model and Data ResidencyOptions and residency are stated with isolation or the processing path left open.
Vendor Published

A real residency statement, which is rarer in this segment than it ought to be. The privacy policy states that the services are hosted and operated in the United States and that personal data will be hosted on servers located there. Cross border handling is addressed rather than ignored: transfers outside the European Economic Area are stated to rely on adequacy decisions or standard contractual clauses, a European Union representative is named with a full address, and a data processing addendum is published.

Held at B on three gaps. No hosting provider or cloud region is named, where a peer in this segment names both of its providers. No alternative deployment model exists, so an institution that requires data to remain inside its own environment has no option here, and there is no residency choice for customers outside the United States. And the list of processors is available only on request rather than published, so the chain of subprocessors handling clinician queries cannot be inspected before contracting.

For context on the residency point, within this segment only Avo publishes a comparable statement, while C8 Health, AgileMD and UpToDate publish none.

Commercial
BB on Commercial TransparencyA price or a pricing basis is published without full tiers, so a buyer can size the cost before making contact.
Vendor Published

The clinician facing price is published, unambiguous and zero. The company states that the product is free for licensed clinicians and trainees, with unlimited searches, on signing up with professional credentials, and repeats it in the frequently asked questions rather than burying it in terms. A clinician can establish the full cost of the product they will actually use without speaking to anyone, which this index has found to be true of very little.

Enterprise is entirely gated. No tier structure, no pricing mechanism, no rate card and no implementation fee schedule were located, and third party reviews describe institutional deployment as custom priced. The tier a health system actually buys is therefore opaque, which is the same pattern recorded against UpToDate, where the transparent tier is the one that matters least to the institutional buyer.

One honest counterweight belongs on the record and it cuts against the usual reading of a free product. Nothing published explains how the product is funded. The privacy policy shows advertising partners receiving analytics data and permits sharing aggregated inputs and outputs with business partners and research organisations, but no revenue model is stated anywhere. A buyer assessing durability, and a clinician deciding what to type into a tool that costs nothing, both have a legitimate interest in knowing who pays for it.

BB on Setting and Specialty CoverageCoverage is named with validation behind part of it.
Vendor Published

Breadth is claimed across the board and the supporting features are consistent with it: a corpus given as more than 60 million papers and guidelines, drug and interaction checking, a calculator library the company numbers in the hundreds, stated availability in every language with region aware results, and stated use from outpatient clinic through to hospital. ACEP states the product is available to clinicians across all specialties in the United States and internationally.

Depth is concentrated somewhere much narrower and the vendor's own pages show it. The flagship partnership is with an emergency medicine college, the clinical council chair is a former chair of emergency medicine, and the majority of named clinical advisors hold emergency medicine appointments, with anaesthesia, paediatrics and oncology thinly represented. An independent review of the product raised the same point and asked for broader specialty representation over time.

Held at B because availability across settings is established while demonstrated usefulness outside emergency medicine is not, and because the evidence grading logic that carries the whole product is directed by a council weighted towards one specialty. Ask which specialties the council actually covers and how content outside those specialties is reviewed before publication.

What Vera Health is, and how it differs from a general purpose assistant

The AI Health Index records Vera Health as a clinical reference and evidence product rather than a general medical chatbot, and the distinction is architectural rather than promotional. The company describes a retrieval first design: search a curated corpus of peer reviewed literature, guidelines and care pathways, rank the results, apply evidence grading logic comparable to the work of a guideline methodologist, and only then generate a short answer whose sentences carry inline citations to the specific sources behind them. Around the search it ships drug and interaction checking, a calculator library, differential and treatment planning views, and specialty tailored literature updates, and it accrues continuing education credit per search. Access is free to verified clinicians and trainees, which is unusual in a category where the established products are institutional subscriptions. Verified as of Aug 2, 2026.

How Vera Health grades on the AI Health Index, and what a clinical leader should ask

The AI Health Index grades Vera Health A on AI Centrality, C on Clinical and Operational Evidence, B on Autonomy and Oversight Model and C on AI Liability and Recourse, verified as of Aug 2, 2026. Read together those separate a well specified product from a thin public evidence base. Citation grounding is a design claim about how answers are produced; it is not the same as published evidence that clinicians using the product reach better decisions, and the evidence grade records that the second has not been established in public. The governance signal is more encouraging: direction comes from a named international clinical council chaired by a former academic emergency medicine chair, and a specialty society has placed its own clinical policies inside the product, both of which are checkable facts rather than claims. For a clinical leader the questions that follow are narrow: what the corpus does and does not include, how often it refreshes, and what the product does when the evidence it retrieves is weak or conflicting.

Common questions

What is Vera Health?

Vera Health is a clinical evidence search engine for licensed clinicians, operated by Veracity-Health Inc., which answers clinical questions from a corpus of peer reviewed papers, guidelines and care pathways and returns short answers with inline citations tied to specific statements. It also provides drug and interaction checking, a clinical calculator library, differential and treatment planning views and specialty tailored literature updates, and it accrues continuing education credit per search. The product is free to verified clinicians and trainees with unlimited searches. The AI Health Index indexes it in clinical reference and evidence with secondary placement in clinical decision support, and grades it across fifteen capability axes with the date of last verification published on the record.

Is Vera Health free, and who can use it?

It is free to verified clinicians and trainees with unlimited searches, which is the clearest commercial difference between it and the subscription products it is usually compared against. Verification of clinical status is the gate rather than payment. The AI Health Index grades Vera Health B on Commercial Transparency as of Aug 2, 2026, and notes that free at the point of use is a pricing model rather than an absence of one: the questions a health system should still ask are what the institutional offering costs if one exists, what happens to the free tier if it changes, and what the product does with query data, since in this category the search itself is the valuable asset.

How does Vera Health compare to UpToDate and OpenEvidence?

They answer the same clinical question in three different ways and the AI Health Index does not rank them into one order. UpToDate is editorially authored: humans write and maintain topic reviews, so the answer is a curated synthesis with a named author. Vera Health and OpenEvidence both generate an answer at query time from retrieved literature with inline citations, which is faster to the specific question and puts the burden of judging the retrieval on the reader. Within that second group the differences worth checking are corpus composition, how evidence quality is graded before an answer is written, and what each product publishes about accuracy. The AI Health Index grades Vera Health C on Clinical and Operational Evidence as of Aug 2, 2026, and applies the same axis to every vendor in the category so the comparison is like for like rather than a feature list.

Is Vera Health safe to use with patient information?

The AI Health Index grades Vera Health A on HIPAA and BAA Posture, B on AI Safety and PHI Stewardship and B on Security Certifications and Trust Center as of Aug 2, 2026. The HIPAA grade is its strongest disclosure result and is unusual for a product distributed directly to individual clinicians rather than through an institutional contract. The practical caution is about use rather than posture: a clinical reference tool is designed to answer a question about a condition, not to receive an identified patient record, so the safest pattern is to ask the clinical question without the identifiers. That is a workflow instruction rather than a product deficiency, and it applies to every product in this category.

Does Vera Health pay to be listed on the AI Health Index?

No. The AI Health Index is researched from public sources, no vendor pays for inclusion, for a grade or for placement, and every record carries the date it was last verified. A vendor that publishes more is regraded and the change is logged.

The clinician facing price is stated plainly on the company's own pages and in its frequently asked questions: free for licensed clinicians and trainees, with unlimited searches, on signing up with professional credentials. No paid individual tier was located, so unlike the subscription incumbents in this segment there is no ladder to read.

Everything institutional is gated. No enterprise tier structure, pricing mechanism, rate card or implementation fee schedule was located on the vendor's material. Third party review directories describe enterprise features, including electronic health record integration, as custom priced and requiring technical coordination, but those are aggregator sites rather than the vendor and are recorded here as context rather than as a figure.

One disclosure that a buyer should weigh alongside the zero. No revenue model is published anywhere. The privacy policy names advertising partners as recipients of device, internet protocol, geolocation and web analytics data, and permits sharing aggregated inputs and outputs with business partners and research organisations. That is website marketing analytics rather than advertising placed inside a clinical answer, which is a materially different arrangement graded elsewhere in this segment, but a product that costs nothing is funded somehow and the vendor has not said how.
