Anthropic and OpenEvidence announced a partnership on September 22 and 23, 2026, according to Reuters and The Next Web. A specialized version of OpenEvidence will be free to healthcare providers in about 100 low and middle income countries. Named examples include Uganda, Angola, Sudan, Haiti, and Mongolia. The companies did not disclose financial terms.
What is OpenEvidence?
A medical search tool. It answers clinicians’ questions using peer-reviewed research and treatment guidelines, and it’s already free to clinicians in the U.S. and Europe. Founder Daniel Nadler told Reuters that U.S. clinicians consulted the platform 42 million times in August. That’s a company-reported count of consultations. It says nothing about accuracy or patient outcomes.
What does each company do?
Anthropic provides back-end support, according to Reuters. OpenEvidence tailors the system to each region’s health infrastructure. Nadler said development is designed to adapt to local context, and he noted that most doctors have smartphones even where clinics lack electricity.
OpenEvidence began adapting its tools with health organizations in Rwanda and Botswana earlier this year. In Rwanda, working with the Rwanda Biomedical Center and Resolve to Save Lives, 45 local doctors and nurses tested the tool and suggested changes, according to The Next Web. That’s a small test, and we found no published health outcomes from the Rwanda or Botswana work.
Anthropic president Daniela Amodei said “the market incentives alone” would not make this happen without “entrepreneurial, philanthropically minded work.” Nadler said, “Access to medical knowledge shouldn’t depend on geography.”
Who Benefits and How
Clinicians in low and middle income countries benefit first. A doctor or nurse working alone could check a drug dose or a treatment guideline in a free tool on a smartphone. Patients gain only indirectly, through better-informed care. The reports describe a plan, with no launch date for each country, no patient version and no published health outcomes yet.
Why does access matter so much?
Our World in Data reports that high-income countries have around ten times as many doctors per person as low-income countries. Its chart shows about 3.78 doctors per 1,000 people in high-income countries and about 0.38 in low-income countries, using 2022 data. A reference tool cannot replace a missing doctor. It may help a clinician working alone check a drug dose or a guideline.
Who can use the free version, and can patients?
Clinicians in eligible low and middle income countries. Reuters and The Next Web do not publish the full list, so check OpenEvidence for your country. No source we read gives a launch date for each country. “About 100 countries” describes the plan, and rollout appears to be staged. The reports describe a tool for clinicians, not a patient version.
Is the answer always right?
No source we read claims that. Clinicians should treat the tool as a reference and use their own judgment, especially where local drugs and disease patterns differ from the research it draws on. Reuters notes critics worry that systems trained mainly on data from high-income countries may not fit local practice.
