Decode Your Health with AI

AI can read your medical records, spot patterns across years of data, connect dots between symptoms, and help you prepare for doctor visits with the right questions. This guide shows you exactly how to set it up.

Free guide. No technical skills required.
Why AI?

Your medical records are full of insights no one has time to find

Doctors have 15 minutes per visit. AI has unlimited time to read everything, cross-reference results, and find what matters.

📄

Reads Everything

Upload PDFs of blood tests, imaging reports, prescriptions, specialist notes. AI reads them all in seconds.

🔗

Connects the Dots

AI can cross-reference your blood work with imaging results, medications, symptoms, and lifestyle factors that a single specialist might not see.

📈

Tracks Trends

Instead of comparing lab results yourself, AI spots trends across years of data. Rising cholesterol, shifting thyroid levels, recurring patterns.

💬

Answers Your Questions

Ask anything in plain language. "Why is my ferritin low?" "What should I ask my neurologist?" "How do these medications interact?"

🧠

Remembers Everything

Unlike a conversation that disappears, your health project keeps your entire medical history. Come back days or months later.

🎯

Prepares You for Appointments

Go to your doctor with organized data, identified patterns, and targeted questions that make every minute count.

Which AI to use

Choosing the right tool

There are three major AI assistants today: ChatGPT (by OpenAI), Gemini (by Google), and Claude (by Anthropic). All three can analyze text and answer medical questions.

This guide uses Claude because it is currently the strongest at reading long, complex documents carefully, following detailed instructions, and maintaining context across many files. For medical record analysis, where precision matters, that makes a real difference.

Specifically, we recommend the Claude desktop app and its Cowork feature. Cowork turns Claude into an agent that works directly with files on your computer. You connect a folder, and Claude can read, create, and update documents in it automatically. This is how Claude will build and maintain your Master Health Document, with no manual copying or re-uploading. Your medical data stays on your machine.

A Claude Pro subscription costs around $20/month (about 20 euros). For a tool that can read, remember, and analyze your entire medical history, it is well worth it.

Before Starting

Privacy & Security

🛡️

Your Data is Yours

Claude does not use your conversations or uploaded files to train its models. Your medical data stays private.

💻

Local Files

With Cowork, your medical files and Master Health Document live in a folder on your computer. Nothing is uploaded to the cloud.

🔍

Anonymization (Optional)

If you prefer, you can redact personal identifiers (name, address, social security number) from your documents before uploading. Use Preview on Mac or PDF-XChange Editor on Windows.

🔑

Account Security

Use a strong, unique password and enable two-factor authentication on your Claude account.

The Guide

5 steps to decode your health

From zero to personalized health insights.

1
Create Your Health Project
5 minutes

First, set up the Claude desktop app with Cowork:

  1. Subscribe to Claude Pro ($20/month) at claude.ai
  2. Download and install the Claude desktop app (Mac or Windows)
  3. Open the app and switch to the "Cowork" tab at the top (next to "Chat")
  4. Create a folder on your computer called "My Health". Put all your medical PDFs and documents in it

Now create your health project:

  1. In Cowork, create a new Project
  2. Choose "Use an existing folder" and select the "My Health" folder you just created. Claude will ask for permission to read and modify files in it. Accept
  3. Name the project "My Health"
  4. In the project Instructions field, paste the following. These tell Claude how to behave in every task you run inside this project:
You are a world-class medical analyst and holistic health strategist. I'm sharing my complete medical history in this project.

For every analysis:
- Be thorough and evidence-based while embracing a holistic view
- Explore beyond conventional boundaries: nutrition, lifestyle, stress, sleep, microbiome, environmental factors
- Clearly distinguish established science from emerging research and hypotheses
- Be specific and actionable: give concrete next steps, not vague advice
- When recommending supplements, be selective. Prioritize the 3-5 that matter most for my specific situation, with clear reasoning. Avoid long generic lists
- You are helping me prepare for conversations with my doctors, not replacing them

Master Health Document:
- A file called "master-health.md" exists in this project folder. It is the single source of truth about my health
- Every time I upload new blood results, medical reports, or share new information, you MUST update master-health.md with the new findings, updated trends, and revised recommendations
- Always tell me what you changed and why
- If you notice something concerning or a trend worth flagging, update the document and tell me proactively

These instructions are set once and apply to every task in the project. Claude also has memory within your project: it remembers what you discussed in previous tasks and builds on it over time.

2
Upload Your Medical Records
10 minutes

Put all your medical documents into the "My Health" folder on your computer. Since this folder is connected to your Cowork project, Claude can read everything in it directly. No uploading needed.

What to put in the folder:

  • Blood test results (complete blood count, metabolic panels, hormones, vitamins)
  • Imaging reports (MRI, CT scan, X-ray, ultrasound)
  • Consultation notes, specialist letters, prescriptions
  • Surgical reports, discharge summaries
  • Any other medical document you have

Tips:

  • Add everything you have. More data means better analysis
  • Claude reads PDFs natively, so no conversion is needed
  • Paper documents? Scan them with your phone first (Notes on iPhone, Google Drive on Android, or Adobe Scan)
  • Don't worry about organization. Claude will sort through it
3
Let Claude Interview You
15 minutes

Your medical records don't contain everything. Your lifestyle, symptoms, family history, daily habits, all of this matters. Instead of trying to write it all down yourself, let Claude ask you the right questions.

Start a new task in your Cowork project and send this:

You now have access to my medical records. Before we start any analysis, I want you to interview me. Ask me every question you need to build a complete picture of my health — things that aren't in the documents.

Cover: lifestyle, diet, sleep, exercise, stress, family medical history, symptoms I experience regularly, medications and supplements, allergies, past surgeries, mental health, environmental factors, goals.

Ask questions one group at a time. Wait for my answers before continuing.

Once the interview is done, tell Claude to build your Master Health Document. It will create the file directly in your folder:

Create my Master Health Document as "master-health.md". Combine everything from my medical records and our interview into one organized file. Include:

- Personal profile (age, gender, height, weight, blood type)
- Complete medical history with timeline
- Current medications and supplements
- Known conditions and diagnoses
- Family medical history and hereditary risk factors
- Lifestyle factors (diet, exercise, sleep, stress)
- Key lab values and their trends over time
- Active concerns and areas to monitor
- Recommended specialists: which doctors I should see and why
- Medical tests or screenings I should ask for
- Supplement plan: the 3-5 most important for my situation, with dosages and reasoning
- Lifestyle changes: specific, prioritized actions I should take
- Questions for my next doctor visits

You will keep this document updated every time I share new results or information.

Claude will create master-health.md directly in your folder. From now on, every task starts with your complete profile, and Claude updates this document automatically whenever you share new information.

Start Your Health Research
The powerful part

Now that Claude has your full picture, start new tasks in your project and explore. Here are 9 research prompts to get you started:

Prompt 1: Full Analysis
Based on everything you know about me, give me a thorough health analysis. What stands out? What trends do you see? What should I be paying attention to? What connections might my doctors have missed?
Prompt 2: Timeline & Trends
Create a detailed chronology of my health: major events, diagnoses, how symptoms evolved, and correlations between treatments and changes.
Prompt 3: Treatment Options
What conventional treatments have I tried? What new approaches (drugs in development, clinical trials, innovative therapies) could be worth exploring? Distinguish established from experimental.
Prompt 4: Which Doctors Should I See?
Based on my health profile, what types of specialists should I be seeing? Which medical tests or screenings should I ask for? Are there any doctors I should see that I haven't considered? Prioritize by urgency.
Prompt 5: Blind Spots
What might conventional medicine be missing? Consider microbiome, environmental toxins, nutrient deficiencies, and insights from functional medicine, TCM, or Ayurveda.
Prompt 6: Appointment Prep
I have an appointment with my [specialist] on [date]. Prepare a list of precise questions based on my history to make this consultation as productive as possible.
Prompt 7: Smart Supplements
The supplement world is overwhelming. Based on my blood work, conditions, and lifestyle, which supplements actually matter for me? I don't want a long list. Give me the 3-5 most impactful ones, with exact dosages, when to take them, why each one specifically helps my situation, and what to look for when buying them. Flag any that could interact with my medications.
Prompt 8: Lifestyle Changes
What are the most impactful lifestyle changes I can make for my specific situation? Cover diet, exercise, sleep, and stress. Be concrete: not "eat healthier" but specific foods, specific routines, specific habits. Prioritize by impact — what will make the biggest difference first?
Prompt 9: Deep Dive on Treatments
For each treatment I should consider: how it works, evidence for my condition, typical protocol, benefits, risks, costs, and questions for my doctor.
5
Keep It Updated
Ongoing

Your health project grows with you. Every time you get new lab results, see a specialist, or start a new medication:

  • Drop the new files into your "My Health" folder
  • Start a new task and tell Claude what's new. It will automatically update your Master Health Document with new findings, updated trends, and revised recommendations
  • No need to start over or re-explain your history. Claude remembers everything from previous tasks and has access to all your files

Just say something like:

Here are my latest blood test results. Compare with my previous ones, flag anything that changed significantly, and update the Master Health Document. Also update my supplement and lifestyle recommendations if needed.

Over time, your Master Health Document becomes a living record that tracks your health trajectory. It's always current, always complete, and always available for your next doctor visit or health decision.

Go Deeper

Your family's health is part of your health

Many conditions have genetic or environmental links that only become visible when you look at the family picture.

Family medical history is one of the most powerful tools in health analysis, and one of the most underused. Heart disease, diabetes, autoimmune conditions, cancer, mental health patterns: these often run in families, and knowing about them can change what you screen for, how early you act, and which lifestyle changes matter most.

People are sometimes reluctant to share medical details, and that's understandable. But even basic information helps: what conditions your parents, siblings, or grandparents have been diagnosed with, at what age, and what treatments they've had.

The ideal approach: help your close family members go through this same process. Each person creates their own health project. Then, with their permission, you share the Master Health Documents with each other. Upload your family members' summaries into your own project, and Claude can start finding connections: shared risk factors, hereditary patterns, conditions to watch for.

At minimum: during Claude's interview (Step 3), answer the family history questions as thoroughly as you can. If you're not sure about details, ask your family. A quick conversation with a parent about their health history could be one of the most valuable things you do.
