AI chatbot reaches two-thirds of US doctors despite accuracy concerns

Summarised from 2 outlets · Updated 21 Oct, 19:08 · Archive

Nearly two-thirds of US doctors use an AI-powered search engine called OpenEvidence to help diagnose and treat patients.

Nearly two-thirds of US doctors are using OpenEvidence, an AI-powered chatbot, to help diagnose and treat patients, propelling the Miami-based startup to a $15 billion valuation. Founded by serial entrepreneur Daniel Nadler in 2022, the tool helps doctors search medical journals and clinical guidelines. Last month, America's doctors processed more than 42 million prompts through the platform.

The ad-powered service has grown largely through word of mouth and has attracted nearly $1 billion in investment over the past 18 months from backers including Andreessen Horowitz, Blackstone, Thrive Capital and Sequoia. The company raised $250 million in September at its current valuation. OpenEvidence booked $100 million in advertising commitments for this year and is on track to generate between $400 million and $500 million through ads by the end of 2026, according to sources close to the company.

Medical professionals have found the chatbot helpful for easing workloads. However, researchers have raised concerns about the accuracy of its results as doctors become increasingly dependent on the AI tool to shape patient treatment decisions. The platform also faces growing competition from larger AI companies such as OpenAI and Anthropic entering the healthcare space.
