Take control over your health data across providers and countries. HDA parses, translates, summarises, and structures all your health records from 25+ formats + soon wearables and apps, with focus on medical records and logs. Chat to your complete health picture, spot gaps & trends; identify sensitive info and selectively redact it, safely plug into LLMs, share what you choose via fine-grained access controls. Essential for migrants, health tourists, longevity enthusiasts and chronic health

Healthcare data is still incredibly fragmented, especially when people move between countries or providers.
An app that can organize medical documents across languages, borders, and healthcare systems could remove a lot of friction for patients and doctors alike.
Really interesting concept. Curious, how does HDA handle data privacy and interoperability with different healthcare providers?
Congrats on the launch and excited to see how this evolves!
@dharmikp1908 thank you, Dharmik!
Great question!
Right now our interoperability layer is the user — they bring their records together themselves, combining documents with their own logs. And even as we build more provider partnerships and integrations (like InterSystems), everything inside HDA will still only ever be initiated by the user managing their own data. That's a design principle, not just a feature.
On privacy & security: all data storage and processing takes place within GDPR-designated regions. We use Microsoft Azure for infrastructure, and our AI pipeline runs on either Azure or Nebius AI — both GDPR-compliant. We don't route health data outside these regions for any reason, including AI inference, and all model calls are made against infrastructure covered by our data processing agreements.
Are you.adding more languages in the future?
@archie_miller_bakewell when it comes to handling your data we're language-agnostic by design. Our UI is currently limited to English, but we are working to expand this.
Is there a function for analyzing results? Does it just copy the information, and the AI adds it to the system and gives its recommendations?
Congratulations on the launch! A really important and impactful problem to be working to solve, and a great use of these new technologies.
How has the private beta been going, what do users love the most?
@benblume Thank you! The beta users loved the PII redaction - being able to highlight sensitive data, and then output a Markdown file suitable to then pass to GenAI tools like Claude for further analysis. This was really helpful feedback, as I had initially feared it would be too niche.

We built Health Data Avatar real health journeys not as an extension of a tool made for hospitals or insurers.
This is so useful, thank you for building it! I have a very long, complicated medical history and am under the care of different NHS trusts. They each have their own separate systems so they can't access the others' results etc and I have to try to keep track of everything myself - this will help so much!
@rutheliasjones thank you so much! This is exactly why we built HDA. You just described the experience of millions of people in the UK alone, holding everything together yourself because the systems simply don't talk to each other, and the cost of gaps falls entirely on you. Just acknowledging this reality, and instead of (or at least alongside) endlessly pouring money into new Electronic Health Records for clinics and overwhelming new standards, offering a tool that is actually designed around the patient's needs.
So glad you found us! And please do reach out if there's anything that would make it work better for your specific situation. Stories like yours are what keep us going 💙
Let’s talk about carers!
This could be many of you: those who take care of your family’s health count too. And in real life, there’s rarely just one unpaid carer for one person — juggling health records across a family can quickly become a nightmare.
If you’re a mother, can you actually delegate a doctor’s appointment for your child?
Who would be there to provide all the information that only you know?
HDA solves this with multi-user profiles (available in Premium), enabling families to co-manage a single patient’s record — a use case no competitor has truly addressed.
