Using AI in the context of health needs to be done very carefully and in conjunction with medical providers. Please do not accept any AI output blindly. With great power comes great responsibility for your own health.

Ever since ChatGPT launched, I (like everyone else) have used AI for personal healthcare advice. LLMs were unreliable in their advice until December 2025. With GPT 5 and above, from my experience, the capabilities crossed the threshold from mostly wrong to mostly right. Especially for basic health questions.

I have observed that reaching out to AI for quick personal healthcare queries is now getting more and more accepted within my social circles. And as the capabilities have grown, my reliance on AI for personal health advice has only grown in equal measure. My confidence grew with a combination of a) increased raw model intelligence and b) the various tools/workflows/skills that AI can use to power itself. The game changer for me was agentic harnesses such as Codex/Claude Code etc.

There is a big gap in the quality of output a default out-of-the-box AI gives, versus what it can potentially do with the right tools. This is true for a whole raft of use cases, like coding etc., where the harness matters as much as the base AI model. And personal health is an area where this gap exists.

I am building for that gap. I am also writing this post to jot down my experience so far.

Over the last 2 years, my questions went from very basic questions such as “I have a fever, and I took 650 mg of paracetamol about Y hours ago. How long do I wait to repeat it?” to health problems that can only be attacked by talking with AI over a period of weeks/months and then gradually homing in on something that helps manage, understand or solve an issue. Issues like - chronic pain that has recurred for the last few years and gets worse randomly, new symptoms of continuous coughing (even though the person is not infected nor do they have any illness) that started randomly and now does not go away.

These issues are complex, multifaceted and frequently do not have a clear answer. It is much more common to see cases where there are multiple health issues happening simultaneously that need to be managed or addressed. Doctors, of course, are the specialists that can solve these. In the current healthcare systems, a doctor is not available 24/7 to answer every tiny question one has. It is also not feasible for them to have the capacity to remember every detail about one person’s health and whatever affects it. Especially things that are from weeks/months/years ago. The health data is scattered across time and space, and it requires a tremendous amount of effort to keep track of everything manually. The body remembers but the doctor cannot.

This is where AI excels. It is a health companion that can take the full context of an individual. I am talking about years of history that can be cross-checked, correlated, and matched to the latest research online and then tailored to that specific individual in that specific case for that specific query that is a pressing concern for that user at that moment in time.

It is a superpower.

This power, when harnessed correctly, can yield surprising insights into a person’s health that only a dedicated family doctor could uncover earlier. An involved family doctor is a very rare thing in the world. But an AI is not.

The app for the gap

It is called CareLoop. It helps you manage your family’s health. The way it works is pretty simple on the surface. Pour all your data and questions into the agent. The agent will ingest it properly, create proper timelines, structures etc. to keep track of everything and then ask you follow-up questions. You tell it the concerns you want to explore and ask it to suggest next steps. Do those steps (with your doctor where it matters), and then review the result. Loop over and over again and see how it helps.

It runs locally; no servers are required, and no data is shared with anyone externally (except the AI provider). All the data that the agent writes is stored locally within the working folder. The agentic app creates structured information out of all the data and then uses it to help the user in addressing their health-related queries.

It has completely transformed the way I approach personal health. It makes me more informed about the state of my health. Second opinions are easy, and in-depth silly questions are frictionless to ask. It has also made me consider a lot of things I would not have thought of before.

It will not solve problems that are...
