Why the Fitbit app now says Google Health
If you own a Fitbit, you already have an account here, it just does not look like Fitbit anymore. Your Fitbit device is unchanged. The app it syncs to became Google Health in May 2026, and the Fitbit Web API that developers used sunsets on September 30, 2026, which is why the connection now runs on Google's Health API. Everything on your wrist keeps working exactly as it did.
That is also why some screens in this guide say Google Health and others still say Fitbit. Wellness Project keeps the label Fitbit on the device connection, since Fitbit is the account you are signing into, and reaches it through Google's API underneath. For the full breakdown of Google Fit, Google Health, and Health Connect, and which one applies to you, see Google Fit vs Google Health vs Health Connect.
How ChatGPT reads it as a connector
Google ships no MCP server for Google Health. Wellness Project connects to Google's Health API over OAuth, holds the synced history, and runs the MCP server ChatGPT reads through its connector. ChatGPT never authenticates with Google itself; it authenticates with Wellness Project, which already did the work of syncing and structuring your Fitbit history into rows a conversation can query.
You add that connector to ChatGPT once, as a plugin, and from then on any chat can pull from your synced history. Nothing gets pasted in and nothing expires the next time you start a new conversation.
Set it up in five steps
The setup runs through your Fitbit account and Wellness Project, not a Google developer console or an API key you generate yourself.
Get the Wellness Project app
Download Wellness Project for iPhone or Android with the buttons above, or sign in on the web. Signing in with Apple or Google takes one tap, the account is free during early access, and this is the app that stores your synced history and serves it to Claude and ChatGPT over MCP.
Connect your Fitbit account in Wellness Project
Open Settings, Devices, Fitbit, and sign in with the same Google Account your Google Health app uses. In Wellness Project this connection is called Fitbit, because Fitbit is the account you own. Google Health is Google's API behind it. Steps, Active Zone Minutes, sleep stages, and resting heart rate sync automatically from there.
Add the Wellness Project MCP connector to ChatGPT
Add Wellness Project as a ChatGPT plugin and authenticate with the key from your account settings. This is the one connection ChatGPT reads your Google Health-sourced data through, so you set it up once rather than pasting a screenshot into every chat.
Check what synced
Open Wellness Project and confirm steps, Active Zone Minutes, sleep stages, and resting heart rate are populated. You get about a year of history at connect, and it keeps building from there, so ChatGPT has real weeks to compare from your first question.
Ask about your data in plain language
Open a chat and ask. "How did my resting heart rate move this month?" "Did my sleep get worse on high-step days?" "What were my Active Zone Minutes last week?" ChatGPT answers from the structured rows Wellness Project holds, not a pasted screenshot.
For the connector itself and the tool surface it exposes to ChatGPT, see the ChatGPT integration page. This guide is the walkthrough; that page is the product.
Health Connect is a different product
Google Health is the app your Fitbit data lives in. Health Connect is a separate, Android-only layer that lets other apps share health data with each other on your phone, and Google Health is only one of the apps that can connect through it. If you also have Android data coming from apps other than Fitbit, see connecting Health Connect to AI instead, and the full three-way distinction lives on the Google Fit vs Google Health vs Health Connect comparison.
What to ask ChatGPT once it is connected
The setup pays off once the questions move past a single day. Because ChatGPT reads structured history instead of a pasted number, ask it things a screenshot never could.
Try "How has my resting heart rate trended over the past month?" Try "Which weeks had the most consistent Active Zone Minutes?" Try "Did my sleep hold up during my highest step weeks?" Because the same layer holds every device you connect, those answers can draw on Fitbit alongside Apple Health or Oura, not just one app in isolation.
Give ChatGPT your synced Google Health history.
Connect your Fitbit account through Google Health, add the ChatGPT plugin, and ask about your actual trends. Free during early access.
