AI-Powered Symptom Checker
Problem statement
The COVID-19 pandemic left hospitals and clinics under unprecedented strain, as patients with low-priority symptoms struggled to get seen by a doctor. It was difficult for patients to tell what was truly an emergency, leading to some going to the ER unnecessarily. Virtual consultations could provide a more appropriate alternative, but doctors lacked reliable pre-consultation data to speed up workflows and accelerate treatment.
Solution
HOW IT WORKS
An intelligent symptom interview, powered by a conversational AI interface, adapts its questions dynamically based on patient responses to capture accurate health information. This feeds into a risk assessment engine that evaluates urgency levels and supports effective triage. From there, care pathway navigation automatically directs patients to the most appropriate level of care, whether self-care, telemedicine, or in-person consultation. Finally, a pre-consultation data package compiles the gathered insights into a comprehensive summary, equipping healthcare providers with the information needed to deliver timely and focused treatment.
TECHNICAL INTEGRATION
Knok integrated Infermedica’s clinical AI engine into its digital platform to enhance symptom analysis and patient triage. The solution ensured GDPR and HIPAA-compliant handling of sensitive health data, addressing both European and international regulatory requirements. Leveraging the API-first architecture, Knok implemented the system as a white-label solution, embedding the AI seamlessly into its existing workflows. As a result, patients received accurate guidance in their native language, while clinicians benefited from structured, pre-consultation data that streamlined care delivery.

Outcome
The AI-Powered Symptom Checker demonstrated high accuracy in symptom assessment, aligning closely with physician evaluations and supporting more reliable patient guidance. By reducing unnecessary emergency room visits, it helps ease the burden on healthcare systems while directing patients to more appropriate levels of care. Healthcare providers benefit from significantly faster pre-consultation preparation, as the solution collects comprehensive data points during each patient interaction. From a user experience perspective, the platform achieves strong satisfaction ratings, with patients consistently completing assessments and being guided toward the right care pathways. This not only enhances patient confidence but also streamlines provider workflows, enabling more focused and efficient consultations.
Reflections
Designing conversational flows that mimicked natural doctor-patient dialogue and integrating visual tools like interactive body mapping were crucial to reducing user anxiety and encouraging completion. Collaborating closely with engineers and clinical experts, I learned the importance of aligning design decisions with both regulatory standards and patient expectations. This project reinforced my belief that thoughtful design can transform intimidating healthcare processes into empowering digital experiences.

Solution
HOW IT WORKS
We built a tech system that combined multiple advanced components to ensure reliable, immediate health information. Essentially, a computer vision engine leverages AI-powered facial recognition to detect heartbeat through face scans, without any gadget touching the patient’s skin. This engine is complemented by sophisticated signal processing algorithms that filter noise and movement blur, so readings remain clear and precise even in dynamic environments. Thanks to real-time analytics that translate these signals, doctors are able to track patient health indicators instantly while speaking with them, giving them immediate and actionable insights. All output results go through strict checks of data validation protocols designed to meet medical-grade accuracy standards.
