How healthcare AI tools actually break down
"Healthcare AI" covers products that have almost nothing in common with each other. A tool that drafts your clinical notes and a tool that flags a brain bleed on a CT scan are both called healthcare AI, but they are bought by different people, priced differently, and regulated differently. Before comparing anything, work out which of these six groups you are actually shopping in.
1. Ambient AI scribes — the fastest-growing group
These listen to the patient visit and draft the clinical note. It is the category most clinicians mean when they say "AI is finally useful." Abridge, Nuance DAX Copilot, Suki, Nabla Copilot, DeepScribe, Freed AI, Ambience Healthcare, Commure Scribe, Corti and Sully.ai all compete here.
The differences that matter are unglamorous. How deeply does it write back into your EHR — does the note land structured in the right fields, or does someone paste it in? How does it handle a patient who switches languages mid-sentence? What happens on a bad microphone in a noisy room? Every vendor demos beautifully in a quiet office with clear speech. Ask to trial it in your worst room.
The other split is who they are built for. Some target large health systems with Epic integration and a long procurement cycle. Others are self-serve and priced for a solo clinician who wants to stop writing notes at 9pm. Buying the enterprise product as a two-person practice is how people end up paying for an integration they never use.
2. Medical imaging AI
Aidoc, Viz.ai, Qure.ai, RapidAI, Lunit, Zebra Medical Vision (Nanox AI) and iCAD (DeepHealth) analyse scans and flag findings — stroke, pulmonary embolism, nodules, breast cancer, fractures.
This is the group where regulatory clearance is not optional. A tool making a diagnostic claim needs the appropriate clearance for your country — FDA in the US, CE/UKCA in Europe. Clearances are specific: a product may be cleared for one finding on one modality and not for the next thing you assumed it covered. Always read what the clearance actually says rather than what the marketing page implies.
3. Digital pathology
PathAI, Proscia, Paige AI, PathPresenter and Leica Biosystems work on digitised slides. The blocker here is almost never the AI — it is whether your lab has slide scanners, storage, and a workflow that survives digitisation. Labs that buy the software before solving the scanning pipeline end up with an expensive viewer.
4. Symptom checking and triage
Ada Health, Infermedica and Sensely sit at the front door — patient-facing questioning that routes someone to the right level of care. Health systems and insurers buy these to reduce unnecessary visits. They are decision support, not diagnosis, and every serious vendor says so explicitly.
5. Mental and behavioural health
Wysa, Woebot Health, Limbic, Spring Health, Brightside Health, Lyra, Eleos Health and Headspace Health range from CBT-based chatbots to full employer-sponsored care platforms with human clinicians behind them.
Two very different products get shelved together here. A conversational self-help app and a platform that books you a licensed therapist are not substitutes. Check whether there are real clinicians in the loop and what the escalation path looks like when someone is in crisis — that answer tells you more about the product than any feature list.
6. Drug discovery and research
Insilico Medicine, Recursion Pharmaceuticals, Owkin and Flatiron Health serve pharma and research, not clinics. Long sales cycles, scientific partnerships, nothing you evaluate on a free trial.
What to check before you buy
EHR integration decides everything. For anything touching documentation, the question is not "is the AI good" but "does the output land in the right field of the right chart without a human retyping it." A brilliant scribe that produces text someone must copy across has removed almost none of the work.
Get the BAA in writing. In the US, any vendor handling protected health information must sign a Business Associate Agreement. Do not accept "we are HIPAA compliant" on a marketing page as proof — ask for the agreement. Outside the US the equivalent question is GDPR processing terms and where data is stored.
Ask what happens to your audio and text. Is it used to train models? Can you opt out? How long is it retained, and can you delete it? Answers vary enormously between vendors that look identical from the outside.
Pilot with your hardest cases. Accents, code-switching, background noise, complex multi-problem visits, an interrupted consultation. Demos use clean audio and simple cases. Your Tuesday afternoon does not.
Understand the pricing model, not just the number. Most clinical tools price per clinician per month; enterprise imaging and pathology tools price by volume or site licence. Ask specifically about implementation fees, integration costs and minimum contract length — those are where the real money usually is.
Measure time saved, not satisfaction. Before the pilot, record how long documentation actually takes. Measure it again after. Vendors will quote impressive averages from other customers; only your own numbers tell you whether it worked for you.
Where this is genuinely working today
Ambient documentation is the clearest win. Clinicians consistently report finishing notes earlier and going home earlier, and that is a real outcome even when accuracy is imperfect — a draft you edit beats a blank page at 9pm.
Imaging triage is the second. Reordering a worklist so the likely stroke is read first does not replace the radiologist; it changes what they see first, and minutes matter in those conditions.
The areas still oversold are autonomous diagnosis and anything promising to replace clinical judgement. Treat those claims with the scepticism you would apply to any extraordinary claim, and ask for published evidence rather than case studies.
Informational only. Nothing here is medical advice, a clinical recommendation, or a substitute for professional judgement. We are not affiliated with any vendor listed and nobody pays for placement on this page. Verify regulatory clearance, pricing and data-handling terms directly with each vendor before purchasing.
