Nobody is ever taught how to keep a history of their own health.
How long? How bad? How often? What has changed?
Four questions your doctor will ask. Almost nobody will answer them properly, because nobody was ever taught how.
OnionAI is a health record you write yourself, on a foundation built by doctors. It teaches you your own history as you record it, one layer at a time.
So, when it matters, you arrive prepared, with something a clinician can relate to and act upon in seconds.
This is where personalised healthcare begins. Receive the care you deserve, and the care your clinician wants to give.
OnionAI. Your Health. Your Story.
Healthcare has never known more about us. Yet understanding our own health has never been harder.
A clinician can only personalise your care if the history in front of them makes sense: how severe a symptom is, how long it has run, how it varies, when things actually happened, what you have stopped tolerating over the years. What a ten minute appointment usually produces instead is your best effort from memory, under pressure, on the spot.
That is not a failing on anyone's part. It is because nobody has ever shown you how to build a history before you walked in. We built OnionAI to change that.
Better understanding. A more active role in shaping your health.
Our mission is to build the most trusted and useful place for adults to understand their own health. Think of OnionAI as a digital health passport: it documents where you have been, explains where you are now, and travels with you into whatever comes next.
Evidence first
Health information you can trust. Our learning content is created by clinicians, reviewed by clinicians, and delivered in plain language. OnionAI is a licensed provider of NICE syndicated content.
Fact, not dogma
We deliver fact, not dogma. We keep the science simple, transparent and calm, because fear and hype paralyse people rather than empowering them.
Understanding
Medicine is complicated. We do not think it needs to sound complicated. We make health information easier to understand without losing the substance that makes it useful.
Ownership
Your Health Story is authored by you. You decide what belongs in it and build a record that reflects your health and your experience of it.
Always accessible
Your health does not stop when the surgery closes. Your Health Story should not either. It is built to be there at two in the morning before an appointment later that day, or in a new doctor's waiting room.
Partnership
Better conversations, not a replacement for your doctor. OnionAI is designed to support the relationship between you and the professionals who care for you.
Clear boundaries
We help you understand. We do not diagnose, and we do not tell you what to do. OnionAI records, explains and prepares. It never assesses. Those decisions belong to you and with your healthcare professionals.
Privacy
Health information is deeply personal. Protecting it is not an added feature; it is fundamental to the product we are building. OnionAI holds Cyber Essentials Plus certification.
Built by people who know healthcare and believe it has to work better for patients.
OnionAI brings together doctors, technologists, patient advocates and communicators with experience across healthcare, research, education and technology.
Expertise from across healthcare.
Our ambassadors bring experience from across medicine, surgery, general practice, nursing, research and medical education, helping us build health information that reflects the breadth of people healthcare serves.
