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 Hevy sets, reps and weights in any chat after that, with no connector to pick.

Ask Grok about your Hevy data

“How has my bench press moved over the last eight weeks in Hevy?”

GrokExample
Up 7.5 kg. Your top set went from 80 kg × 5 to 87.5 kg × 5 in eight weeks, and you benched twice a week in all but one of them.

From the video. Answers depend on your data.

Limits

Limits, said plainly

  • Needs Hevy Pro for the API key. Without a key, a workout Hevy saves to Apple Health or Health Connect still comes in from there, as a strength workout with its time and estimated calories, without the sets; Hevy's sync to them has to be on, and it doesn't send older workouts.
  • Memory.fit reads Hevy and writes nothing back to it.
  • Your key is stored encrypted and never shown again; revoke it in Hevy at any time.
  • The first read goes 90 days back.
  • Your AI's own subscription is separate from Memory.fit's.

Questions

Hevy in Grok, in short.

  • Not from Hevy. Memory.fit is a hosted MCP server: connect Hevy 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 Hevy 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.
