You can connect your AI assistant (ChatGPT, Claude, etc.) to Welltory and talk with it about your data. Once connected, it can pull up Welltory's analysis of your:
Health: your HRV compared with your own norm, resting heart rate during sleep, and any unusual measurements.
Energy and Stress: how your energy changed during the day, your physiological stress level, and time spent in harmful stationary stress and rest.
Sleep: sleep score, duration, sleep stages, and heart rate at night.
Activity: steps, active minutes, calories, and cardio fitness, plus your workouts from today and yesterday.
HRV measurements: the results of each measurement you took, as the Heartbeat Report or Nervous System Snapshot.
History: for Health, Energy, Stress, Sleep, and Activity, your assistant can look back up to 60 days and see trends for up to 90 days.
The connector only reads your data. It can't change anything in your Welltory account or app.
Try to finish all the steps in one go: if you stop halfway, you'll need to start over.
Before you start
You'll need:
An iPhone with the Welltory app. Android isn't supported yet.
A Welltory Care subscription.
Welltory allowed to read your Apple Health data.
Your Welltory sign-in details at hand: you might need to log in to the web version of Welltory with the same account you use in the app.

That's all. You don't need to change any other settings.
Perplexity

Your first question
Before you ask, open Welltory on your iPhone. Then try something simple:
"How am I today? Check my Welltory data."
"Why is my energy low today?"
"Is my HRV within my normal range right now?"
"What does my Welltory data say about last night's sleep?"
"How has my sleep changed over the last 30 days?"
"How has my energy changed over the last two weeks?"
"Give me a summary of my week: sleep, stress, and activity."
"Compare this week with last week."
If you connect other sources to your AI assistant, e.g., your calendar, you can ask about them together. For example: "Look at my calendar and my Welltory data for the past month. On which days does my energy drop after a busy schedule?" In the same way, you can compare your Welltory data with any other source you connect.
Welltory scores are wellbeing estimates from consumer devices, not medical readings. For any health concern, please talk to your doctor.
If something doesn't work
Most of the time, the fix is simple: your assistant gets your data straight from your iPhone, so Welltory needs to be running there. It works when Welltory is open or minimized, even with your screen locked. If you swiped it closed, it can't answer. If the assistant can't reach Welltory after a long break, just open the app again.
What you see | What to do |
The assistant says Welltory didn't respond, or waits about 30 seconds | Open Welltory on your iPhone, check your internet connection, and ask again |
You can't find Welltory in the chat | ChatGPT: type @ and choose Welltory. Claude: + → Connectors → turn on Welltory. Gemini: type @ and choose Welltory. Perplexity: type @ and choose Welltory, or click + under the message box → Connectors → tick Welltory |
Your AI assistant says it can't see your data | Ask directly: "Use Welltory to check my data" |
It asks you to sign in again | Go to the connector settings, disconnect Welltory, then connect it again |
The data is empty, or it says there's no access to Health | On your iPhone, check that Welltory is allowed to read Apple Health data |
The data looks off, or it's empty while the app has data | You may have used a different email or sign-in method than in the Welltory app. Disconnect Welltory in your assistant's settings, and to connect again, sign in the same way you do in the app |
The assistant says there's no data for a day | That's okay: your iPhone simply has no data for that day. Try another day |
Gemini doesn't use Welltory | Check that Keep Activity is turned on in your Google account |
