Connect COROS to Grok

Yes. Connect COROS in the Memory.fit app, add one Memory.fit address to Grok, and Grok reads your activities, sleep, HRV and resting heart rate.

Grok can also plan structured sessions, and Memory.fit sends them to your COROS.

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.
Workouts sent to your COROS
Yes. Once Grok plans a structured session, Memory.fit sends it to your COROS. Up to 90 days ahead, and a session your AI changes is updated there.
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 COROS runs and sleep in any chat after that, with no connector to pick.

“How has my resting heart rate moved with my training load this month?”

GrokExample
It rose from 47 to 51 bpm across your two biggest weeks, 58 and 61 km, and settled at 48 in your easier week. It followed the load closely.

From the video. Answers depend on your data.

  • Your AI's own subscription is separate from Memory.fit's.
  • The first read goes 90 days back.
