Doctors in roughly 100 low- and middle-income countries will soon gain free access to OpenEvidence, a clinical search tool already used by physicians in the United States and Europe. The platform will run on Anthropic's AI models, and the two companies said the rollout targets regions where limited access to medical journals, specialists, and continuing education can make patient care more difficult.

OpenEvidence helps doctors find answers to clinical questions by searching peer-reviewed research journals and established treatment guidelines. Daniel Nadler, the company's founder and CEO, said the platform draws on multiple sources in its responses, including the New England Journal of Medicine and the NCCN guidelines, the cancer-treatment standards published by the National Comprehensive Cancer Network.

The rollout includes countries such as Uganda, Angola, Sudan, Haiti, and Mongolia. In the United States, doctors made 42 million queries through OpenEvidence in August alone, Nadler told Reuters. He also estimated that several hundred million Americans will have been treated in 2026 by doctors who used the platform — figures that illustrate the tool's existing scale in US clinical practice.

Why Anthropic is giving it away

Anthropic President Daniela Amodei said the project would probably not have happened through normal market incentives alone. She told Reuters that the technology has become capable enough for the initiative, but that “market incentives by themselves would not cause it to happen” without a philanthropic push.

Nadler summed up the goal simply: “Access to medical knowledge shouldn't depend on geography.”

Unreliable electricity is a major challenge in many of the targeted low-resource settings. According to Nadler, one advantage of the platform is that most doctors in these areas still have smartphones, even when clinics face power inconsistencies. In practice, that makes the smartphone in a doctor's pocket the delivery channel, rather than clinic infrastructure.

Can the tool work outside wealthy healthcare systems?

Critics have warned that medical AI tools trained largely on evidence from wealthier countries may not always fit healthcare systems with different practices and conditions, Reuters reported. Where treatment patterns, disease profiles, or available therapies differ, guidance drawn from other countries' data may translate imperfectly to local care. OpenEvidence says it is addressing the concern by adapting the system to each region rather than taking a simple one-size-fits-all approach.

“One hundred percent of what we are developing for these areas is designed to be context adaptive,” Nadler said.

Earlier this year, the company worked with healthcare organizations in Rwanda and Botswana to adapt its tools.

The expansion could prove especially valuable for doctors with limited access to major medical journals. Dr. Ahmed Bendary, a cardiologist at Benha University in Egypt, told Reuters that the rollout is especially important for physicians in places where access to medical research is limited.

Anthropic pushes deeper into healthcare

Last week, Anthropic announced a laboratory for physical biology research aimed at drug development, as previously reported by Cryptopolitan. The Wall Street Journal also reported in August that Anthropic sees its healthcare and biology work as a way to improve public sentiment around AI — of the arguments it has made to investors ahead of a planned public listing. The free rollout adds a frontline clinical dimension to that strategy.

The bigger test for the OpenEvidence platform will be whether a tool built largely on medical evidence from wealthy countries can work just as well for doctors in less affluent places such as Mongolia, Sudan, and the other countries named in the launch.
