It can predict over 3,000 diseases before symptoms appear. It can save over $300 billion in annual healthcare costs. And it can slash drug discovery timelines by up to 50%.
We could spend this whole article just talking about AI, healthcare, and these astonishing numbers. But this exponential impact of AI could perhaps be best summarized in the words of Mayo Clinic's Dr. John Halamka:
"Five years from now, it will be malpractice not to use AI.”
In this article, however, we won't be focusing on the use of AI in clinical settings. Instead, we'll explore how AI is empowering individuals to take control of their personal health and longevity.
Arguably, AI's most remarkable quality—in any field—is how it improves accessibility. That extends to health as well. In many contexts, you don't have to sit in a doctor's office or have a medical degree yourself to reap the benefits of AI.
For those who are health-conscious and seek continuous improvement to their lifestyles, several AI tools are already at a level where they can provide actionable insights to enhance their routines, helping them live a longer, healthier life. And that's on all aspects of holistic longevity, not just what to eat or how to exercise.
So today, we'll highlight five AI tools you can add to your routine right now to level up your longevity.
Gemini Deep Research is the natural progression of the classic Google search: a trusted research partner perfectly tailored to your exact questions. Instead of sifting through dozens of links and conflicting information, you can now receive a synthesized, coherent, and evidence-based report about any topic you could think of.
For personal health and longevity, this capability is invaluable. Before Gemini goes searching for your answers in hundreds of web pages, it first presents you with a research plan for your approval. This ensures the output is precisely what you need.
For example, if you ask about a new supplement, you can instruct the model to limit its search to only peer-reviewed, reputable journals—a massive advantage for getting reliable information you can trust. This level of control allows you to be an informed and active participant in your own wellness journey. You can ask the precise questions that matter to your unique situation and receive a meticulously researched response.
Furthermore, how the information is delivered is entirely up to you. You can ask Gemini to generate a TL;DR report with simple, actionable guidance or a Google Sheet that’s ready to be integrated into your regular routine.
You can even request an Audio Overview, which generates a short, personalized podcast where two hosts chat about your topic in a lighthearted yet informative tone. This makes complex information not only accessible but also genuinely engaging, helping you seamlessly integrate new insights into your daily life. It’s an evolution from simply finding data to having a personal knowledge best friend.
Air pollution is an invisible threat to our longevity, estimated to shorten a person's lifespan by an average of 1.8 years. The air we breathe directly impacts our healthspan as well, making clean air a cornerstone of a longer, healthier life. This is where having the IQAir AirVisual app installed on your phone proves valuable.
This tool uses machine learning to provide you with a holistic view of your air quality. The app gives you real-time air quality and pollution readings, detailed weather reports, and seven-day forecasts from over 500,000 locations worldwide. By using the app's alerts, you can be notified when the outdoor air quality isn't safe.
Beyond just outdoor air, the app allows you to monitor your indoor air quality as well, comparing it to the air outside in real time. This is crucial since indoor air can sometimes be more polluted than outdoor air.
This data empowers you to make smarter decisions about your day-to-day life. For instance, if the air quality is poor, you might decide to run an air purifier, close your windows, or wear a mask if you must go outside. The app also includes health recommendations.
IQAir AirVisual’s partnership with the UN Environment Programme also means it is a reliable source of information, helping to bring air quality data to the public. Ultimately, this app is a practical example of how AI can transform a large-scale public health issue into a personalized and actionable tool for your daily routine.
Even though it's the largest organ in our body, skin is an often-overlooked part of longevity. The early signs of many skin conditions can be subtle and easy to miss. But performing regular self-tests can help you catch and treat anomalies quickly. It's a habit that's as integral as brushing your teeth, according to the Skinive app.
Skinive is designed to help you with weekly skin self-exams using AI in three simple steps. You start by taking a photo of an area of concern, and the app uses its AI capabilities to help assess the condition of your skin. The third and final step is ongoing monitoring, which is critical for maintaining skin health and tracking changes over time.
The app uses a sophisticated neural network trained on a large database of clinical cases to analyze skin conditions from a simple photo. This allows the app to assist with preventive care and is a critical part of managing existing conditions. The app’s algorithm has a 90% accuracy rate, comparable to that of professional dermatologists, and can help you assess the risk for over 50 different conditions. These include common issues like acne and psoriasis, as well as more serious concerns like melanoma.
By making these self-checkups easy and accurate, Skinive helps you stay on top of your skin and act quickly if something changes, all from the comfort of your home.
Brain health is an essential component of longevity, and maintaining cognitive function is a key goal for all of us. Because it's not always easy to monitor your brain health, BrainTrack was designed to help you monitor and understand changes in your thinking and memory over time.
Funded by the Australian government and developed in collaboration with the Applied Artificial Intelligence Institute at Deakin University, BrainTrack uses AI to analyze your performance on a series of fun, travel-themed games. These games are not just for entertainment; they are adapted from validated cognitive testing and are designed to assess key cognitive skills like attention, memory, and spatial orientation. New games unlock every 30 days, allowing you to compare your results longitudinally.
The AI then provides insights about your performance, helping you to identify potential changes that might be difficult to notice otherwise. This information can be exported into a confidential report to share with a doctor as a starting point for discussion. The app also educates you on how to reduce modifiable risk factors for dementia.
By making you more aware of your cognitive function and empowering you with data, the BrainTrack app gives you a powerful way to manage your brain health. With over 100,000 downloads, it has become a globally recognized and award-winning resource.
