What it can do

What Grok can do with it

Plans written back
Yes. Grok reads your training, sleep and fuel, and can plan around them.
Meal photos
In part. Grok sees your meal photo and logs the meal, but can't hand the photo itself to Memory.fit unless it can run code with internet access.
Where it runs
grok.com and the Grok apps.
Good to know
This page is for Grok, the assistant on grok.com and in the Grok apps, not Grok Bot. You add Memory.fit once in the Grok phone app, under Settings › Connectors › Custom Connector, and Grok reads your Withings weigh-ins in any chat after that, with no connector to pick.

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 Grok, in short.

  • Not from Withings. Memory.fit is a hosted MCP server: connect Withings in the Memory.fit app, add one Memory.fit address to Grok, and Grok reads it.

  • Memory.fit is $9 a month or $69 a year, with 7 days free, for every device and every AI you connect. Grok's own plan, if it has one, is separate.

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

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

  • Yes. In the Grok app, open Settings › Connectors, scroll to Custom Connectors, tap Custom Connector, then Connect. Name it Memory.fit, paste the address and tap Add Connector, then sign in with your Memory.fit account.
