Best behavioral health AI

Almost every published answer to this question is an ordered list, and an ordered list requires a weighting: a decision about which failure matters most. That decision belongs to whoever is carrying the clinical risk. Publishing an order does not remove the weighting, it hides it inside a position number that looks like a measurement.

Two organizations can correctly reach opposite conclusions about the same product. An employer buying a self guided app for a population that mostly will not use it is underwriting a utilization risk. A community mental health center putting an intake model in front of people in crisis is underwriting a clinical one. There is no order that serves both, and pretending otherwise is how a buyer ends up with the tool that markets best.

So what follows is the whole roster graded on the same axes, then shortlists cut by failure mode. Of the 25 vendors here, 19 are primarily behavioral health companies and 6 arrive through a second category, which is worth knowing because the second group is often stronger on infrastructure and weaker on clinical evidence.

Every vendor in the index carries a grade on all 15 axes before it is published at all, so this table compares the same questions answered for every vendor rather than the results of uneven research. Counts are of vendors, as of August 31, 2026.

The shape of that table is unusual and it is worth reading twice. 6 axes have nobody at the bottom grade at all, including Clinical and Operational Evidence, where 5 vendors hold a top grade, and Autonomy and Oversight Model, where 5 do. That floor is not true of most categories in this index. Behavioral health arrived at AI from a discipline that already ran on validated instruments and clinical supervision, and it shows.

Then look at the bottom rows. 3 axes return a top grade for nobody: AI Governance and Bias Disclosure, AI Liability and Recourse, Model Supply Chain Disclosure. Every one of them is about accountability rather than capability, and the first is the one that matters most in this specific category.

That combination is the finding. The category is comparatively good at proving its products work and comparatively silent about who they work less well for, which is a difficult position to hold at the same time.

Not one of the 25 vendors here earns a top grade on AI Governance and Bias Disclosure. Across all 554 vendors in this index, spanning every category, 11 do, so behavioral health is not an outlier. It is an ordinary result in the place where it is least affordable.

The reason it is least affordable here is mechanical rather than political. These products infer a mental state from speech, from written text, or from responses to screening instruments. Those instruments have documented differences in sensitivity across language, culture, age and presentation, and a model trained on their outputs inherits every one of them. A tool that under detects distress in one group and over detects it in another will still report excellent aggregate accuracy.

The distribution is not a floor: 6 vendors hold a B and 18 hold a C on this axis, with 1 at the bottom. Most of this category has said something. None has said enough to verify. The grade records what a counterparty can check from published evidence, so a B here usually means a stated commitment without the population level results behind it.

The practical consequence for a buyer is a question rather than a veto. Ask for accuracy broken out by the populations you actually serve, ask what happened when the vendor last looked, and treat an answer that arrives only under NDA as an answer. This index cannot grade what is not published, and neither can your risk committee.

No vendor in this category earns a top grade on AI Liability and Recourse, and 13 of 25 sit at the bottom grade. Before treating that as a behavioral health problem, note the scale of it: across all 554 vendors this index grades, in every category, exactly 1 earns an A on that axis.

This is the single clearest thing the index has found, and it is an industry position rather than a category one. Published terms in health AI generally offer the service as is, disclaim warranties, and leave the clinician or the organization holding the output.

Model Supply Chain Disclosure is thin for a related reason. 12 of 25 vendors sit at the bottom grade, and none reaches the top. A product that processes a therapy transcript through a third party model has a supply chain, and most of this category has not described it in public.

The buyer response to both is the same and it is short. Accountability is not going to be transferred to the vendor by a standard contract, so design your own review step first and choose the product that fits it, rather than choosing the product and hoping the contract covers you.

Exactly 1 vendor in this category holds a top grade on FDA and Regulatory Status. In the ambient scribe category the equivalent number is zero and that is the expected answer, because a scribe drafts a note a clinician signs and sits outside device regulation by design.

Behavioral health is not like that. Parts of it genuinely are regulated: a product making a diagnostic claim, or delivering a therapeutic intervention on its own, can fall inside the device pathway, and some have gone through it. So a low grade on this axis here is more informative than the same grade elsewhere in the index.

That cuts both ways, and screening on this axis alone would be a mistake. Most of this roster is clinician facing infrastructure: documentation, session review, intake routing, measurement collection. For those products no clearance is claimed and none is required, and the grade records an absence rather than a deficiency. Read it alongside Autonomy and Oversight Model, where 5 vendors hold a top grade, because the pair together tells you whether a product is making a clinical decision or handing one to a clinician.

Each list below is every vendor in the category holding the top grade on the named axes. They are not ranked, they are alphabetical, and a vendor appearing on none of them is not disqualified. It has not published what these axes ask for, which is a question to raise rather than a verdict.

Two of these lists are empty, and an empty list is a result. It says that the question has no vendor level answer available in public today, so it becomes something to ask in a demo rather than something to filter on.

If more than one of these is your failure mode, take the intersection yourself rather than looking for a vendor that appears everywhere. Almost none do.

The widest record in the category holds a top grade on 8 axes of 15. The median record holds 2. There is no vendor here that clears every bar, and a comparison built on the assumption that one exists will end in a tie broken by brand recognition.

The gap between the widest and the median is large, and most of it is disclosure rather than product. A vendor with eight top grades is usually a vendor that has published a trust center, a security attestation, outcome results and a pricing page, not a vendor whose software does eight more things.

That is a useful thing to know before a demo. The strongest records in this category tend to belong to companies that decided to publish, which is a signal about how they will behave as a counterparty and a weaker signal about clinical quality than it looks.

Every behavioral health AI vendor in the index, each graded on all 15 axes with a source and a date on every judgement. Inclusion is not purchasable and no vendor pays for placement or review.
