What it can do

What ChatGPT can do with it

Plans written back
Yes. ChatGPT plans your week, fuels your long sessions and writes it all back to Memory.fit.
Meal photos
Yes. Send ChatGPT a photo of your meal: it logs the meal and can pass the photo itself to Memory.fit, so it saves with the entry.
Scheduled check-ins
In part. ChatGPT can schedule tasks, but OpenAI does not say a scheduled task can use a custom connector like Memory.fit. Try it once.
Where it runs
The web, desktop and phone apps. Adding Memory.fit needs chatgpt.com on a computer.

Other routes

Withings in ChatGPT without Memory.fit

Withings has no official route to ChatGPT. The nearest is OpenAI's own:

From OpenAI

ChatGPT Health, through Apple Health

Where
US only
Needs
ChatGPT on iPhone, with the Withings app sharing to Apple Health
The catch
It sees only what the Withings app writes to Apple Health, it works on iPhone in the US only, and it keeps no plan or fuel targets you can see in another app.

Limits

Limits, said plainly

  • Memory.fit reads Withings and sends nothing to it.
  • The first weigh-in of the day is the day's weight, and other readings that day are kept with their time.
  • With a Withings watch, your workouts come in too, and your nights with a watch or a Sleep Analyzer.
  • Your whole weigh-in history comes in.
  • Your AI's own subscription is separate from Memory.fit's.

Questions

Withings in ChatGPT, in short.

  • Not from Withings. The nearest is ChatGPT Health, through Apple Health, from OpenAI: US only. ChatGPT on iPhone, with the Withings app sharing to Apple Health. It sees only what the Withings app writes to Apple Health, it works on iPhone in the US only, and it keeps no plan or fuel targets you can see in another app. Memory.fit is another route, a hosted MCP server: connect Withings in the Memory.fit app, add one Memory.fit address to ChatGPT, and ChatGPT reads it.

  • Memory.fit is $9 a month or $69 a year, with 7 days free, for every device and every AI you connect. ChatGPT has its own requirements: on a computer, about two minutes.

  • Memory.fit works in every country, and ChatGPT's requirements name no region.

  • ChatGPT gets only the permissions you allow, every change shows in the Memory.fit app with who made it, and you can disconnect ChatGPT or Withings at any time.
