Anthropic partners with OpenEvidence on medical AI

Anthropic and medical knowledge platform OpenEvidence announced a partnership to develop diagnostic tools powered by artificial intelligence. The initiative offers a specialized version of the platform free of charge to healthcare workers across roughly 100 low- and middle-income countries, including Uganda, Angola, Sudan, Haiti, and Mongolia.

OpenEvidence answers medical questions using peer-reviewed research and clinical guidelines, and is already free for healthcare professionals in the United States and Canada. In August alone, US physicians consulted OpenEvidence 42 million times, according to founder Daniel Nadler, who added that several hundred million Americans will be treated in 2026 by a physician using the tool to guide care.

Anthropic technology will power the tool, while OpenEvidence adapts the system to local healthcare infrastructure. OpenEvidence previously worked with health organizations in Rwanda and Botswana to tailor its tools to local disease patterns and treatment availability. The companies did not disclose financial terms for the deal.
