HDA is a multilingual, privacy-first platform that transforms scattered health records into a unified, real-world data AI-driven profile.

Many of the things that are worth tracking for longevity can’t be tracked automatically. But even among the records that you get from clinics and labs we often focus on the population norm rather than our personal baseline and what’s functional for us.

The most valuable health data for preventive care and longevity is surprisingly “boring” and almost never tracked properly:
– what is normal for you
– how fast you recover
– what happened before symptoms started
– early warning signs before illness
– medication effects
– cognitive changes
– days when you feel “off” but can’t explain why

This is the data that helps detect problems early, understand triggers, and get diagnosed faster.

The problem is that this information is rarely captured and even if we do record it somewhere, it’s scattered across notes, apps, PDFs, patient portals, conversations and your memory.

This is exactly why we built Health Data Avatar — a place where you can bring your entire health story together, see patterns, and actually use your data when it matters.
Because preventive care is impossible without longitudinal data, and the cleanest longitudinal data can’t happen without your active contribution.

I’ve met enough clinicians to know most of them are doing their best — often under impossible conditions, with whatever information they happen to have in front of them at that moment.
The problem is that the information is almost never complete.
A doctor treating you in London doesn’t see the scan you had in Madrid. The cardiologist doesn’t see what the GP wrote last year. The A&E team at 3am doesn’t see your allergy. Not because anyone failed — because the data lives in 12 different places and nobody thought to bring it together.

Research confirms what patients already know from experience. Fragmented records are directly linked to medication errors, misdiagnosis, delayed treatment and redundant testing (PMC, 2024). Fragmented care is an independent risk factor for mortality — confirmed in a 4.7 million patient study (BMC Medicine, 2023). Cancer patients receiving fragmented care have 26% higher mortality risk than those with coordinated care (ScienceDirect, 2024). 6 to 17% of all adverse events in hospitals globally are caused by diagnostic errors — and the root cause is almost always incomplete information at the point of care (WHO).

This isn’t a technology problem — It’s a sovereignty problem. The patient is the only person who has ever had access to their full health history — and until now, no secure place to centralise it and make it usable.

That’s what we built HDA for.

Are you ready to upload your entire medical history to ChatGPT Health?

Here are some facts to bare in mind:

- EU vs US storage: consumer ChatGPT data is currently stored/processed in the US. It’s one of the reasons why the waitlist isn’t available if you’re in the UK/EEA/CH, that matters.
- If you’re considering to use a VPN to access ChatGPT Health anyway, that can:
breach terms
muddy jurisdiction
weaken your local protections
- US authorities can seize access to data held by US companies and have already done so under the CLOUD Act
- Don’t assume HIPAA would protect your data: if your health data moves from a covered healthcare flow into a consumer AI product via an integration, the legal protections don’t apply in the same way.

I’m not saying “don’t use it”. I’m saying: you either don’t feel like your health data leaked or resold would affect you or you must trust that OpenAI and its partners will keep your data secure, use it only for your benefit, honour their privacy promises in the long run and won’t go bankrupt.

Follow for Part 2 (more controversies + what to think about) and tell us if you’ve already joined ChatGPT Health waitlist.

If you’re in the UK, EEA or Switzerland, check out Health Data Avatar we’ve been building for two years. It’s fully GDPR-compliant, tested, encrypted at transit and rest, and already available to chat to your full health picture you can securely store, capture, understand and share with fine-grained privacy controls. Read our story and check out our demo account if you’re not yet ready to try HDA with your own data.

Juggling multiple chronic conditions is the invisible reality for millions: overlapping symptoms, conflicting treatment, and a mental load that never ends.

Another comment overheard on the bus, this passenger begins their overwhelming shift from managing a single diagnosis to navigating the complex, exhausting journey of three.

Let’s talk about the reality of the multimorbidity maze where overlapping symptoms and clashing treatments create a mental burden that never truly subsides.

A new year brings new opportunities to care for ourselves better.

By making health data a resolution, we can move from guesswork to clarity, from reaction to prevention, and from goals to measurable progress.

Happy New Year! 🎆

Festive season can be genuinely magical.
It can also be a minefield: loneliness, grief, family dynamics, chronic illness flare-ups, sensory overload, “why are we pretending everything’s fine?” energy.

A few things that help (and you can borrow my scripts):
1. Pick your mode: Celebrate / Survive / Hibernate. No moral hierarchy.
2. Use one boundary sentence. Repeat it. Don’t over-explain.
3. Budget energy like it’s finite (because for many of us, it is).
4. Pre-plan an exit route (outside/bathroom/quiet corner).
5. Schedule micro-rituals so the day doesn’t swallow you whole.
6. If you need it: allow one “sad slot”. Feel it on purpose, then soften.

If you’re on the move, or your nervous system is already doing a lot — focus on your essentials (sleep, food, meds) and keep your health data readily available with HDA.
