BlockSurvey's AI generates follow-up questions in real time based on each user's response. A user who reports high stress gets a different survey path to one who doesn't — making every session as clinically relevant as a guided intake, at scale. Higher completion. Richer data. No extra questions for users who don't need them.
3x higher completion rates on sensitive health topics when surveys are conversational versus traditional form-based. Long health questionnaires overwhelm users and drive abandonment. BlockSurvey presents one question at a time in a conversational flow — reducing cognitive load, improving focus, and creating the kind of experience users associate with a real health consultation rather than a data collection exercise.
Every response is encrypted on the user's device before it leaves their phone or browser. Your digital health product collects the data it needs — symptoms, vitals, mental health indicators, medication adherence — without creating a plaintext data liability. Only your organisation holds the decryption keys.
Digital health products operating in the US need HIPAA coverage. BlockSurvey covers both, with a BAA issued. Every health data you collect through BlockSurvey is protected health information (PHI) under HIPAA. Using a non-compliant tool to collect is a reportable breach.
