Substance use disorders remain a critical public health issue in the United States. People who use drugs often face stigma, criminalization, and fragmented access to the services that keep them alive — naloxone, sterile syringes, and medication for opioid use disorder among them.
EchoCare proposes an AI-powered companion that offers judgment-free support, evidence-based harm reduction guidance, and real connections to local resources — designed through collaboration with public health researchers, harm reduction experts, peer navigators, and people with lived experience.
What this prototype is — and isn't
This is a design concept grounded in research and domain expertise, not a product that has been user-tested. The people most affected by it — people who use drugs — have not yet had a voice in this design. Chat, resources, and tips are functionally working in this build; Safe-Use Mode is simulated, since no wearable hardware is connected.

Who benefits
People who use drugs, particularly in rural, underserved, or stigmatized communities with limited access to harm reduction and treatment services.
Who may be excluded
People without a smartphone, internet access, or digital literacy. Future versions could include an SMS-based option or shared-access devices through community partners.
Ethical safeguards
EchoCare is always transparent that the chatbot isn't human, and keeps direct pathways to peer navigators, counselors, and hotlines for anyone in distress or crisis.
