What it is

A health chat that knows your own care

Advoca's chat is a health assistant you can ask anything, from "what did my doctor mean by that?" to "is this symptom worth worrying about?". It answers from two places: your own record (your recorded appointments, summaries, journal entries and planned visits) and trusted medical sources, not the open web. Every answer shows where it came from, so you can check it for yourself rather than taking it on trust.

40–80% of medical information given by healthcare practitioners is forgotten immediately, and almost half of what is remembered is incorrect.

Knows your record

One chat that holds your whole record

Health information gets scattered fast across appointments, letters, results and notes you made at the time. Advoca's chat brings it together. Ask "what did my doctor mean by post-exertional malaise?" or "have I had this symptom before?" and it pulls from your own recorded appointments, summaries, transcripts, journal entries and planned visits to answer, showing the parts of your record it used. No more re-reading old notes or re-explaining your story from scratch.

  • Ask about your own care. "What did my doctor mean?" pulls from your recorded appointments, summaries and transcripts.
  • Stop repeating your story. One chat holds your appointments, journal and plans, so you don't re-explain it from scratch.

Trusted answers

Trusted answers that show where they came from

When you're told a term or a treatment option you don't recognise, the open web can be hard to judge, especially when advice is written for another country or makes big promises. Ask Advoca instead. It answers from trusted charities, patient-information sites and medical sources, not the open web, and shows you the source cards behind every answer so you can read them yourself. It's a starting point for understanding and a question to bring to your doctor, not personal medical advice.

  • Answers from sources you can trust: charities, patient-information sites and medical bodies, not the open web.
  • See where it came from. Every answer shows its sources, so you can check for yourself.

Reports & letters

Turn a messy history into a clear letter or report

Explaining months of symptoms, appointments and results to a new clinician is exhausting, especially when you're unwell. Ask Advoca to draft a report or letter for your care team, and it pulls together the relevant appointments, journal entries and results into a clear, structured document you can review, edit and share. It's the difference between handing over a pile of notes and handing over a story that makes sense.

  • Draft it in seconds. Advoca pulls your appointments, journal and results into a clear, structured report.
  • Bring a story, not a pile of notes. Review, edit and share it with your clinician or carer.

Simple or detailed

Answers in your words: simple or detailed

Health information is often written for professionals, not for you. More than 4 in 10 adults struggle to understand health content written for the public, and 6 in 10 struggle when it includes numbers. Advoca lets you switch every answer between Detailed (all the facts, in patient-friendly language) and Simple (just the essentials, in plain, everyday words). Share the Simple version with a parent or partner who finds the jargon hard, and keep the Detailed one for yourself.

  • Switch in one tap. Detailed gives you all the facts; Simple keeps it to the essentials, in plain, everyday words.
  • Share it so it's understood. Give the Simple version to a relative who finds the jargon hard.
HOW IT WORKS

From question to a trusted answer in three steps

  1. 1Ask in your own wordsType any question about your health, from a confusing test result to a symptom you're unsure about. Soon you'll be able to speak it too. There's no form and no right way to phrase it.
  2. 2Get an answer from your record and trusted sourcesAdvoca draws on your own appointments, summaries, journal and planned visits, plus trusted medical sources, and writes a clear answer. It shows the sources and the parts of your record it used, so you can check them for yourself.
  3. 3Save it, share it, or pick up laterKeep the answer in your chat history, ask a follow-up whenever you like, draft a report for your care team, or come back to it before your next appointment. Your whole conversation is saved.

I think the most frustrating thing about having a chronic illness is having your symptoms flare up or you're developing a new one. So you go to your doctors and then boom, you get overstim ulated, the brain fog kicks in, and then you're stuck trying to understand all this new information that they're firing at you. And quite frankly, you just get confused. And then through all of this, you're not actually sure what the next step is. For example, I literally have a phone call appointment with my IBD nurse and literally forget half of what's been said. And having crippling health anxiety, this makes the problem ten times worse. But, there's a but. I've actually been informed about this app called Advica. Here we are. And wow, it is a game changer. So it essentially records your whole conversation with your doctor or your nurse and summarises all the key points, making it easier for you to understand. And then also what the actual next steps are. And on the topic of next steps, it gives you the resources to learn. Great, right? So like in simple terms, it gives you a link to your problem or like problems that you may be facing. And in turn, how's best to tackle it? Or you may just want a little bit more information regarding your appointment just to put your mind at ease a little bit. So, if you're facing any of the challenges that I've mentioned so far, why not give it a go? It's on Apple, it's on Android. And the best part of it all, it's completely free. None of this, it's free for a month and then you've got to pay $12.99 afterwards. You don't lose anything. If anything, it's going to make your life easier, less stressful and just overall better. In my opinion. I'm going to be trying it out. And if you do, let me know how you find it. I'll catch you later. Bye.

Hey everyone, I just wanted to get you onto this little app that I've used today. So it's called Advocat, it's called the Advocat app and it 's by Dr Michael and he reached out and said would you just use it at one of your appointments and see what you think. I used it today and honestly I feel like it's what I've been missing. So I am sick to death of, because I go to three different hospitals across three different trusts and they don't speak to each other, they can't access each other. So one doctor will say one thing and then someone else will say something else and I'm stuck in the middle and I am trying to relay what they've said and I've forgotten and it's a lot. But this app records, so you just tell them, you know, I'm recording, is that okay? And then it literally is like a microphone recorder but then at the end it then uploads your recording and transcribes it for you and it gives you a breakdown of what you said, what they said, it then gives you a simple version or a detailed version, it gives you links at the bottom if you know you're not sure what someone's been like. For mine I was talking about biopsy and and it was like, it sent me a link to Macmillan and then the cancer patient. Honestly, it was actually unreal and I feel like it's something I really needed because of so many miscommunications and I think like last time I had my appointment they told me I was having a PET scan and then they booked me in for a biopsy and when I challenged this they said oh we've got no record of it. I've now got the record of what's being said so it can't be challenged and when I go to my next appointment in a different hospital in a different trust who can't access the letter from my surgeon today I've got that I've got the whole breakdown of it so there is no questioning but I just think if you're someone who likes to keep track but you forget if you're going on your own you don't always take it in or if you're someone who just likes to have the information that like me I think it's absolutely incredible so I'm going to put it on to you at the end and see what you think.

Why Advoca instead of Dr Google or a generic chatbot

Most health chatbots answer from the open web and nothing else. Here's how Advoca is different.

Your questions, answered

Is Advoca's health chat free?

Yes. Everything you need to ask questions, understand your care and manage your health is free when you join our research community. Joining means letting us share your fully anonymised data to help advance research into conditions like yours; you use the app exactly as normal, and when your data is matched to a study, you share in the reward. You can opt out at any time. If you'd rather not take part, our optional premium tier gives you full access without joining, and also unlocks extra features like research-paper search.

Are my chats private? Is my data safe?

Yes. Your data is encrypted in transit and held on encrypted servers in the UK and EU, and you don't need to share any identifying details to use Advoca. Your conversations are part of your record, and you can export or delete them at any time. Appointment recordings stay on your own device — the audio is never uploaded to our servers.

Does Advoca replace my doctor?

No. Advoca supports your care — it never replaces it. It helps you remember, understand and organise what your healthcare team tells you, and answers questions from trusted sources, but it does not diagnose or make treatment decisions. Always follow the advice of a qualified professional.

How accurate are the answers?

Advoca answers from trusted medical sources and your own record, and shows you the sources and the parts of your record it used so you can check them. It's built and overseen by doctors and tested on over 1,000 appointment transcripts. It isn't perfect, and it can occasionally get things wrong, so we always recommend checking anything important with your clinician.

What happens if I ask about something urgent or worrying?

Advoca is not a mental health service or an emergency service, but it has built-in safeguards. It watches for red flags in what you tell it, and if something looks urgent or concerning, it pauses and points you to the right help for your region. In the UK, that's NHS 111 for urgent advice or 999 in an emergency; in the US, it's 911 in an emergency. If you or someone else is in immediate danger, always contact your local emergency number.

Medical disclaimer

Advoca helps you record, understand and organise your care. It is not a substitute for professional medical advice, and it does not diagnose conditions or make treatment decisions — always speak to a qualified healthcare professional.

How the AI works

Advoca's assistant transcribes, summarises and explains your health information, grounded in trusted medical sources and overseen by our clinical team. It does not diagnose or replace your doctor — and, like any AI, it can occasionally get things wrong, so we always show you the sources and full transcript behind its answers.
