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. Polar's Nightly Recharge reaches Grok Bot as Polar rates it, from very poor to very good, with the ANS charge behind it on Polar's own −10 to +10 scale.

Ask Grok Bot about your Polar data

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

Uses:get_daily_metricsget_sleep

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

Grok BotExample
This month is about 19% higher: 540 a week on average, against 455 last month. Your biggest week, 612, was the one with two long rides.

From the video. Answers depend on your data.

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.”

Grok BotExample
Done. Polar rated last night poor, with an ANS charge of −5.8, so Thursday's threshold run moved to Saturday. Thursday is now an easy 40 min run.

Questions

Polar in Grok Bot, in short.

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

  • Your last 30 days. Polar shares 30 days of history when you connect, and every new session, night and Nightly Recharge after that as your watch syncs.
