Frequently Asked Questions

General Questions​

What is the Knidian AI API?​

The Knidian AI API is a medical artificial intelligence service that generates differential diagnoses from clinical histories. It uses advanced language models trained on medical literature and clinical data to analyze patient symptoms and provide structured diagnostic suggestions, triage recommendations, and evidence-based care guidance.

Who can use the Knidian AI API?​

The API is designed for:

  • Healthcare providers (physicians, nurse practitioners, physician assistants)
  • Healthcare organizations and hospital systems
  • Medical education institutions
  • Health technology companies
  • Clinical decision support system developers

How accurate is the Knidian AI API?​

The API has been validated against a wide range of clinical cases and has demonstrated high concordance with expert clinician differential diagnoses. However, like all clinical decision support tools, it should be used to augment, not replace, clinical judgment. The accuracy depends on the quality and completeness of the clinical history provided.

Technical Questions​

What is the maximum length of a clinical history I can submit?​

There is no maximum character limit for clinical histories. The more comprehensive information you provide, the more accurate the results will be. However, we recommend focusing on the most relevant clinical information and prioritizing recent and acute findings for optimal differential diagnoses.

How do I handle sensitive patient information?​

The API does not require personally identifiable information (PII) to generate differential diagnoses. We recommend:

  • Removing or anonymizing patient identifiers before submission
  • Using patient IDs or pseudonyms instead of real names
  • Following your organization's privacy policies and applicable regulations (like HIPAA in the US)

What happens to the data I submit to the API?​

Clinical histories submitted to the API are only processed to generate differential diagnoses and are not stored in any way. We only collect usage metrics and telemetry data from our customers to monitor system performance. No clinical information or patient data is retained after processing. Please refer to our Terms of Service and Privacy Policy for detailed information on data handling.

Does the API work offline?​

No, the Knidian AI API requires an internet connection to function as it runs on our secure cloud infrastructure.

What is the expected response time?​

Typical response times range from 25-30 seconds, but may vary based on the complexity of the clinical history and current system load. We're working on supporting faster response times and streaming the results as they're generated.

Can I integrate the API with my EHR/EMR system?​

Yes, the Knidian AI API can be integrated with electronic health record (EHR) and electronic medical record (EMR) systems. Our RESTful API design makes it compatible with most modern healthcare IT systems. Contact our support team for integration guidance.
