Microsoft launched Copilot Health earlier this month as a dedicated space in its Copilot app that permits users to connect medical records and ask specific health questions (https://www.technologyreview.com/2026/03/30/1134795/there-are-more-ai-health-tools-than-ever-but-how-well-do-they-work/). Amazon announced that its LLM-based Health AI tool, formerly restricted to One Medical service members, would become more widely available (https://www.technologyreview.com/2026/03/30/1134795/there-are-more-ai-health-tools-than-ever-but-how-well-do-they-work/).

The report states there are more AI health tools than ever but questions how well they work (https://www.technologyreview.com/2026/03/30/1134795/there-are-more-ai-health-tools-than-ever-but-how-well-do-they-work/). Vendor announcements provide limited data on independent clinical validation.

No peer-reviewed effectiveness studies or regulatory clearance details for the new Microsoft or Amazon features are cited in the primary coverage (https://www.technologyreview.com/2026/03/30/1134795/there-are-more-ai-health-tools-than-ever-but-how-well-do-they-work/).
