ChatGPT
Wellness Project is a ChatGPT fitness tracker you control with conversation.
Wellness Project ships as a Custom GPT inside ChatGPT, backed by an OAuth-protected REST API. Tell the GPT what you ate, how you trained, how you slept, your data lands in the right tracker, your AI specialists pull it on their next reply, and you never open a separate app.

What's inside
Your fitness data layer, inside ChatGPT
Log meals from ChatGPT
"Log my breakfast: eggs, toast, and a smoothie." The GPT calls Wellness Project; the meal lands in your nutrition tracker; macros are estimated automatically.
Log workouts from ChatGPT
"Log my push day: bench 4x10 @185, pec fly 3x12 @200." The GPT structures the sets and reps; Wellness Project saves the workout and detects PRs.
Log sleep, weight, anything
Most modules Wellness Project tracks are callable from the GPT. Sleep, body weight, supplements, recovery sessions, lab results, wellbeing.
Read your data in ChatGPT
The GPT can pull your weekly summary, recent workouts, last night's sleep, or any specific data point and discuss it with you.
OAuth-protected
Sign in once via OAuth from the GPT; your account is bound to the connection. Revoke at any time from Settings.
Specialist-aware replies
When the GPT pulls your data, Wellness Project includes the relevant specialist context (Coach Jamie's workout history, Casey's nutrition patterns) so replies stay grounded.
In the app
The cleanest way to log: just talk.
For users who already live in ChatGPT, Wellness Project is the backend that makes your conversations actionable. You don’t open a tracker app at the end of every meal. You tell the GPT what you ate, the same way you’d tell a friend, and the data lands structured in the right place.
The same connection also means the GPT can read your data when relevant. Ask “did my running volume go up last week?” and it’ll pull your weekly mileage from Wellness Project, compare to the prior week, and answer with real numbers.
For users who prefer Claude, a separate native MCP server exposes the same data layer at /api/mcp. ChatGPT users get the Custom GPT path; Claude users get MCP. Both reach the same tools.
