Ada Health

Ada Health is a consumer-facing and enterprise AI health assessment platform. Its core product is a symptom checker that conducts a guided clinical interview — asking follow-up questions based on symptoms reported — and returns a ranked list of possible causes with next-step recommendations.

## What Ada Does Well

**Conversational symptom assessment** distinguishes Ada from simple symptom checkers that present a fixed list of questions. Ada's AI asks dynamic follow-up questions based on what the user reports, similar to how a physician builds a differential diagnosis through structured questioning. The assessment adapts to each user's responses rather than following a fixed decision tree.

**Clinical depth** comes from Ada's development with physicians. The medical content is structured around a formal clinical knowledge base and is continuously updated. Ada supports assessment for thousands of conditions and has been validated in multiple peer-reviewed studies.

**Consumer accessibility** makes Ada's AI available to anyone in 11 languages. For populations with limited access to primary care — due to cost, geography, or wait times — Ada provides a credible first step before seeking in-person care. The consumer app is free.

**Enterprise product (Ada for Clinics)** is used by health systems and insurers to pre-screen patients before appointments, collect structured health history, and triage appropriately. This enterprise version integrates with EHR systems.

## Who Ada Is For

Ada's consumer app serves patients who want to understand symptoms before deciding whether to seek care. The enterprise product serves healthcare organizations looking to automate intake and triage. Ada is headquartered in Berlin and has strong adoption in Europe and Africa.

## Limitations

Ada is not a diagnostic tool — it surfaces possible explanations, not diagnoses. Users with serious symptoms should seek care regardless of Ada's output. Like all symptom checkers, Ada has accuracy limitations on rare and complex conditions.
