Ask in plain words.

Ask twyn about your own data. Or connect Claude or ChatGPT with one link, and the assistant you already use reads the same record.

I want to start creatine. Anything in my data I should know?

Without your data

Creatine is widely studied and generally considered safe for healthy adults. If you have a kidney condition, check with a doctor first. I don't have your health history.

A general answer

With twyn

Your April panel shows eGFR 98 and creatinine 0.95 mg/dL. Creatine can raise blood creatinine, which feeds the eGFR estimate, so note your start date before the next panel. There is no urinalysis in your record yet.

Second age

Your blood test has a second age in it.

Nine routine markers from an ordinary blood panel add up to a model estimate of biological age. twyn recalculates it with every new panel, so the only comparison is you against you, a year earlier.

Questions

Before you start.

Is twyn a medical service?

No. twyn collects and shows your data. It doesn't diagnose, treat or prescribe. Decisions about your health stay with you and your clinician.

Where is my data stored?

In Frankfurt, in the EU. When you use AI features, the relevant excerpts are processed by Anthropic, Google or OpenAI under API terms that don't allow training on your data.

What can I connect?

Oura and WHOOP sync automatically. Apple Health comes in through Health Auto Export or an XML export. Lab PDFs in English, Portuguese, Ukrainian and Russian. DNA files from 23andMe, AncestryDNA and MyHeritage. Garmin, Withings and CGM are coming soon.

Do I need my own AI?

No. Ask twyn works inside the app. If you already use Claude or ChatGPT, you can connect it on the Connect or Coach plan.

Can I take my data and leave?

Yes. Export everything in one click, delete your account at any time, and cancel a subscription even without signing in.
