Elon Musk creates 'AI doctor' and it's already hidden on more than 400 million phones

Hello!

An AI bot launched by Elon Musk that could revolutionize the way Americans access healthcare is on millions of phones over the world — and you probably didn’t notice.

Grok’s Launch and Healthcare Ambitions

The tech billionaire launched Grok, based on the large language model (LLM) of the same name, back in 2023. Similar to ChatGPT, it can help answer questions and assist with brainstorming. Musk has since been prompting X users to test Grok’s health advice.

In October 2026, he wrote: “Try submitting x-ray, PET, MRI or other medical images to Grok for analysis. This is still early stage, but it is already quite accurate and will become extremely good.” He added: “Let us know where Grok gets it right or needs work.”

Musk also said it would “dive deep, offering insights from spotting peculiarities in your blood work to interpreting those shadowy blobs on your X-rays.” While admitting it’s not a “real doctor,” the SpaceX CEO noted: “It’s pretty adept at providing initial interpretations. It could point out if your cholesterol levels are on a joyride or if there’s something unusual lurking in your MRI that might warrant a follow-up with an actual medical professional.”

Easy Access via the X App

Grok has been integrated into the X app, with its services available to Premium and Premium+ subscribers for $16 a month — though its tab may have gone unnoticed by many. An initial consultation with a primary care physician in the US costs anywhere between $100 and $200, making Grok a fraction of the price.

Real-World Feedback and Limitations

Despite some missteps along the way — like a broken clavicle being mistaken for a broken shoulder, as reported by The New York Times — Musk has recently shared some “success stories” from people trialing Grok for themselves.

Posting a screenshot of their interaction with Grok, one X user said: “My best friend had back surgery last week. And I helped him with his bandages. But I wondered what Grok would say about how well his wound was healing. Sent it a picture… Grok knows surgery care. Separately used it earlier with my son who has a hangnail that is getting infected. It told us how to care for it until we can get him to the doctor. Your AI doctor is here.”

Grok responded by analyzing the surgery image and explaining what each component indicates, including the wound’s suture lines, bruising, swelling and cleanliness. Meanwhile, others shared their own positive experiences with Grok; one X user said: “yup just did this w blood results” (sic). Another commented: “This could be a game-changer for underserved regions with limited access to specialists,” while a third agreed: “That is huge. Surely this will change the entire medical industry very quickly?”

Expert Caution and Privacy Considerations

However, there are some concerns from experts about sharing personal information with AI. Bradley Malin, professor of biomedical informatics at Vanderbilt University, told The New York Times: “This is very personal information, and you don’t exactly know what Grok is going to do with it.”

While believing Grok and AI to be “promising” starts, Dr Harvey Castro and Dr Marc Siegel told Fox Digital that people must proceed cautiously. Siegel added: “Doctors still need to guide the way or be available remotely to oversee guidance.”

In X’s privacy policy, it says it doesn’t “sell your personal information”; however, depending on your settings, it may provide information “to certain third parties with information to help us offer or operate our products and services.”
