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

Polar in ChatGPT without Memory.fit

Polar 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 Polar Flow sharing to Apple Health
The catch
It sees only what Polar Flow writes to Apple Health: workouts, heart rate during workouts, sleep times, steps and weight. Nightly Recharge and HRV don't go there, and nothing goes back to your Polar.

With Memory.fit

Polar in ChatGPT, anywhere

  • Works in every country.
  • ChatGPT reads your Polar data as Polar records it: the list above.
  • Every AI you add reads the same history, under its own permissions.

Try it

Ask ChatGPT about your Polar data

“Read my Nightly Recharge for the last two weeks and tell me which nights I recovered worst.”

ChatGPTExample
Two nights stand out: last Tuesday, compromised, with an ANS charge of −4.2, and this Sunday, poor, at −6.1. Both came after evening intervals, and you slept under 6 h 30 each time.

From the video. Answers depend on your data.

Uses:get_daily_metricsget_sleep

“Compare my training load this month with last month.”

Uses:get_training_load

“How did my sleep change on the nights after my hard sessions?”

Uses:get_sleepget_workouts

“Move tomorrow's threshold run if my Nightly Recharge is poor, and tell me why.”

ChatGPTExample
Your Nightly Recharge was poor last night, with an ANS charge of −5.8, so I moved Thursday's threshold run to Saturday. Thursday is now an easy 40 min run.

From the video. Answers depend on your data.

Limits

Limits, said plainly

  • Polar shares the last 30 days of history, so older sessions don't come in.
  • Accept Polar's data sharing consents when you connect, or Polar shares nothing.
  • Memory.fit reads Polar and sends nothing to it.
  • Polar shares the last 30 days of history.
  • Your AI's own subscription is separate from Memory.fit's.

Questions

Polar in ChatGPT, in short.

  • Not from Polar. The nearest is ChatGPT Health, through Apple Health, from OpenAI: US only. ChatGPT on iPhone, with Polar Flow sharing to Apple Health. It sees only what Polar Flow writes to Apple Health: workouts, heart rate during workouts, sleep times, steps and weight. Nightly Recharge and HRV don't go there, and nothing goes back to your Polar. Memory.fit is another route, a hosted MCP server: connect Polar 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 Polar at any time.

  • Not the first time. Adding a custom MCP server needs chatgpt.com in a browser on a computer, and takes about two minutes. In the Memory.fit app, Settings › AI agents › ChatGPT › Send it to my computer sends you these steps.

  • No. Memory.fit only reads from Polar. When ChatGPT changes a session, the change shows on Plan in the Memory.fit app.
