The short version

  • Each has a real cost: Annalise.ai the United States cleared indication covers roughly ten findings for triage and notification, far fewer than the model reports, so a buyer who evaluates the full multi-finding output and then contracts in the United States gets a much narrower cleared use.; Koa Health psychPlus acquired Koa Health in June 2026, so buyers are now contracting with the technology arm of an American psychiatry provider group rather than a European digital health company, and roadmap, data residency and European product investment should all be re-examined before renewal.
  • They diverge on capability: Annalise.ai covers Annalise Enterprise CXR, Koa Health covers Stepped care triage.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Annalise.ai

  • The United States cleared indication covers roughly ten findings for triage and notification, far fewer than the model reports, so a buyer who evaluates the full multi-finding output and then contracts in the United States gets a much narrower cleared use.
  • Triage AI reprioritises a worklist but does not change clinical decisions on its own, so departments that do not redesign how urgent studies are picked up see no measurable improvement in time to treatment.
  • Published validation is largely reader study evidence on detection of individual findings; prospective evidence of shorter time to treatment in routine emergency care is thin.
  • The Annalise brand is being migrated under the Harrison.ai name for the critical care offering, which creates ambiguity in multi-year contracts about what product name is actually being supported.
  • A high finding count raises the alert burden, and departments report that low prevalence findings generate false positives that erode radiologist trust unless the alerting thresholds are tuned locally.

Koa Health

  • PsychPlus acquired Koa Health in June 2026, so buyers are now contracting with the technology arm of an American psychiatry provider group rather than a European digital health company, and roadmap, data residency and European product investment should all be re-examined before renewal.
  • Stepped care only produces savings when triage is accurate, and members routed to a self guided module when they believe they need a therapist commonly disengage entirely, which a utilisation report records as low engagement rather than as a triage failure.
  • Pricing is per employee or per member per month across the eligible population, so an employer with modest engagement pays for everyone in order to serve a minority.
  • Clinician availability and language coverage differ substantially by country, so a multinational contract that reads as one global standard delivers a materially different experience in secondary markets.
  • Koa competes against much larger and better funded benefits vendors in the United States, and the acquisition does not change the fact that its brand recognition with American benefits consultants is low, which affects broker driven shortlists.

Answered from the vendors’ own pages

Annalise.ai: How many findings are FDA cleared?

Around ten across chest X-ray and head CT, for triage and notification only. The model reports far more findings than that; the rest are not cleared in the United States.

Koa Health: Is Koa Health still operating?

Yes. PsychPlus acquired it in June 2026 and the brand and platform continue. It is not a shutdown, but the ownership and clinical direction have changed.

Annalise.ai: Is the European position different?

Yes. CE marking under the medical device regulation covers a broader decision support indication than the United States triage and notification clearances, so the same software is a different regulatory product depending on where you deploy it.

Koa Health: Who buys Koa Health?

Employers, health plans and health systems. It is not sold direct to individuals.

Annalise.ai: Does it diagnose?

No. In the United States it is a triage and notification device: it flags studies for earlier review, and the radiologist makes the diagnosis.

Koa Health: How is it priced?

Per employee or per member per month, quoted rather than published, with the rate depending on which steps of the care ladder are in scope.

Annalise.ai: Is Annalise.ai becoming Harrison.ai?

The critical care offering is now marketed under the Harrison.ai name. Ask the vendor to name the contracted product explicitly before signing a multi-year deal.

Koa Health: Does it provide access to psychiatrists?

Clinical access is included in the higher tiers, and the PsychPlus acquisition adds psychiatry provider capacity in the United States. Confirm what your specific contract covers.
