What it can do

What Grok Bot can do with it

Plans written back
Yes. Grok Bot plans and reviews from your real training, and can re-plan a week after a bad night's sleep.
Scheduled check-ins
Yes. Grok Bot keeps working after you close the app, so it can write your weekly review while you train.
Where it runs
A desktop app on macOS, Windows and Linux. A companion app on iPhone and Android, no web app.
Good to know
This page is for Grok Bot, xAI's always-on agent in its own desktop and phone apps, not Grok on grok.com. Withings tells Memory.fit when a new weigh-in lands, so it reaches Grok Bot without you opening the Memory.fit app.

Your Sleep Analyzer logged 7 h 05 on average before your four hard sessions, against 7 h 40 on other nights. The shortest was before Tuesday's intervals, at 6 h 10.

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 Bot, 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 Bot, and Grok Bot 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 Bot has its own requirements: X Premium, Super or Ultra, or a legacy Cursor plan.

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

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

  • In a message. Grok Bot has no settings form for it: ask it to add a custom MCP server called Memory.fit at the address above, check the name and address it shows you, approve it, then tap Authorize and sign in. It works from your next message.

  • Only with a Withings device that records nights, such as a ScanWatch or a Sleep Analyzer. A scale alone sends weigh-ins and body composition.
