Your records.
Your whole history.
Know thyself with AI.

Your health is a puzzle that no one but you carries all the pieces to — and your records are scattered across every clinic, lab, and portal you've ever used. Thylib brings your full medical history into one place. When you talk with the AI you trust, it can read across years of labs, visits, and prescriptions — alongside what you're living through and the latest medical knowledge — to give you health information tailored specifically to your situation.

The library, the conversation, and the literature, together. That's where clarity comes from.

Live demo with realistic sample records — no signup, no card.

See the difference

The same AI. A very different answer.

Generic answers come from generic context. When your AI can read your full medical history — every lab, visit, and prescription — it can actually answer the question you're asking.

You've been on antidepressants for years, and your blood pressure has crept up — read at a different clinic almost every time.

you ask Claude
Is there anything in my records that explains my rising blood pressure?
Without Thylib

Blood pressure can rise for many reasons — weight, salt, stress, sleep, family history, or certain medications. It's worth tracking and raising with your doctor, who can confirm the trend and decide whether anything needs to change.

With Thylib

Yes — it's worth looking at alongside one medication. Lining your blood-pressure readings up against your prescription history, the higher numbers — especially the diastolic (bottom) value — cluster around your bupropion (Wellbutrin) 300 mg periods:

no medication
  2020    BP 121/73

Wellbutrin XL 150 mg
  2021    BP 128/74
  2024    BP 137/87
  2025    BP 120/74

Wellbutrin XL 300 mg
  2023    BP 126/84    day 4 on 300 mg
  2023    BP 156/98    ER visit — chest pain
  2026    BP 139/94    home; diastolic 93–97

On 150 mg your diastolic mostly sits in the 70s–80s; across the 300 mg stretches it runs in the 90s — including an ER visit at 156/98. Bupropion can raise blood pressure dose-dependently, so the timing fits. No single visit caught this, because the readings are scattered across different clinics, years apart. I can't say the dose is the cause — but it's a specific thing to raise with your prescriber. Want the full timeline on one page?

You uploaded your medical records last week. Your annual physical is coming up.

you ask Claude
Please review my latest lab results.
Without Thylib

I'd be glad to help review lab results. Could you share the values, or upload the report? Generally, look for any values flagged outside the reference range and bring those to your doctor's attention.

With Thylib

One thing stands out in your March labs:

Hemoglobin   17.3 g/dL  (H)   ref 13.0–17.0
Hematocrit   53.3 %     (H)   ref 39.0–51.0
RBC count    6.10 M/μL  (H)   ref 4.10–5.70

This same erythrocytosis pattern has been present since at least May 2025 (Hgb 17.1, Hct 50.9), with normal MCV — so it's not iron-related. In a 23-year-old with moderate untreated OSA who isn't consistently using CPAP, secondary erythrocytosis from nocturnal hypoxia is the leading explanation, and it typically resolves once CPAP is used consistently. Worth flagging to your PCP if it's not already on her radar — I can draft a short message for the portal.

You feel fine. Your annual physical was last month and everything came back “normal.”

you ask Claude
Anything in my history I should keep an eye on?
Without Thylib

Without your records I can't say anything specific. In general, keep an eye on blood pressure, cholesterol, blood sugar, and weight, and stay current on age-appropriate screenings. Your doctor can tell you what's most relevant for you.

With Thylib

Each of your results was read as “normal,” but one number has been climbing across your last three physicals:

A1c   5.4 %   →   5.7 %   →   6.0 %
      2023        2024        2025

The most recent value crosses into the prediabetes range, and the steady upward slope matters more than any single reading. No one visit flagged it because each was looked at on its own. This is worth raising with your PCP — caught here, it's often reversible with changes you already know how to make. I can pull the three results together and draft a short portal message for her.

What you get

Answers specific to you.

Grounded in you, not the average patient

Every answer is built on your actual history — not a textbook explanation that may have nothing to do with you.

Connections you'd never spot by hand

Linking and summarizing across years of records is what AI does well — reasoning over your labs, meds, visits, and vitals together, not one slice.

Complex records, made understandable

Years of results, codes, and notes are hard to follow. Thylib brings them together and explains them in plain language.

However much you have to keep track of

You're managing a condition

Diabetes, blood pressure, thyroid, heart — your AI sees the whole trend line, not just today's number.

You're caring for a parent

Add them to a family account and ask on their behalf, without holding every doctor and prescription in your head.

You see more than one doctor

A PCP, specialists, maybe a second hospital system — none of whose records talk to each other. Thylib brings them together.

Method

Your medical history, AI-ready.

Setup takes about two minutes. You connect your records once at thylib.com, turn on the Thylib connector in your AI's settings, and from then on you just ask — in plain language, whenever a health question comes up. Your records keep syncing on their own, so the picture stays current with no upkeep.

Three steps to use Thylib: at thylib.com, connect your records by signing in through Epic or MyChart; in your AI's settings under Connectors, turn on the Thylib connector in Claude, ChatGPT, or Gemini; then in any AI chat, ask a question in plain language.
What's MCP?
Open standard

The Model Context Protocol is the open standard AI assistants use to connect to outside data. Claude calls these connectors; ChatGPT calls them apps. Thylib is a connector for your own health data — your records stay under your control, and your AI of choice queries them when you ask a question.

Same plumbing Anthropic uses for Google Drive, Gmail, and 200+ other connectors. Nothing Thylib-specific to install on the AI side.

Why Thylib

Why not just paste a PDF into ChatGPT?

You can — and for a one-off question, or to pull a single value out of one report, it's honestly the right tool for the job. Thylib earns its keep when you ask health questions from time to time and want instant answers, without the download-and-re-upload chore every time.

Privacy

Data layer,
not data broker.

Your records never touch an ad network or a research database. You control what flows where.

Encrypted in transit and at rest

Your records are encrypted the whole way through. We hold the data so your AI can read it — we don't mine it, and we never sell it.

Per-account isolation

Every query is authenticated and scoped to your data — including inside a family account.

No third-party sharing

We don't share with advertisers, researchers, or insurers. Ever.

Delete anytime

One click removes everything. No retention, no backups kept, no dark patterns.

But what about the AI?
Your AI, your terms

We don't sell or share your data with anyone. The only place your records ever go is the AI you connect — and only when you ask a question. What that assistant keeps afterward is governed by its own privacy settings, so we point you to the no-training options and recommend turning them on.

We never see your conversations, and on our side your records are never used to train any model. You bring the AI you already trust; we stay the data layer underneath it.
