Infermedica vs Ubie
The two symptom triage products most often named in the same conversation, and only one of them is regulated for the job. Infermedica is certified as a Class IIb medical device in Europe, guiding a patient from an undifferentiated symptom to a level of care over a physician curated knowledge base, and it embeds inside other organisations' products. Ubie is free and unregistered, covering more than a thousand diseases through an adaptive questionnaire built on published literature under physician supervision, with an unusually strong evidence posture for a consumer tool. For a patient at home, either is a reasonable place to start. For an organisation putting triage into a care pathway, the certification is not a formality: telling someone how urgently to seek care is a regulated act, and inheriting that obligation without the device behind it is the risk.
- It is certified as a Class IIb medical device in Europe and registered with the relevant regulator, which is the correct and much higher bar for software that tells a patient how urgently to seek care.
- Three routes to inspection exist where most vendors offer none, including a published architecture description over a physician curated knowledge base covering around a thousand conditions.
- It is interface first, so a health system or insurer can embed triage inside its own product rather than sending patients to someone else's.
- It is free with no registration, so an organisation can point patients at it without procuring anything and a patient can use it without an account.
- Coverage spans more than a thousand diseases through an adaptive questionnaire built on published literature under physician supervision, with a strong evidence posture for a consumer product.
- It publishes its clinical data sources and process rather than describing them, which is rare at the consumer end of this category.

The regulatory asymmetry is the decisive fact: one product is certified as a medical device for exactly this purpose and the other is a free consumer tool, and a health system embedding either into a care pathway inherits obligations that differ accordingly. Ubie collects sex, age and history through a consumer structure a buyer should understand before directing patients to it.
Neither publishes performance across health literacy, language or cultural background, which is the central validity question in symptom triage, since the system understands some descriptions better than others and sends the rest to the wrong place.
