How did I sleep last night?
Searching your Fit AI Connect dataRead 30 nights of sleepget_sleep
7 h 12 asleep, with 1 h 34 of deep sleep. That's 16 minutes more deep sleep than your 30-night average. You woke twice, both before 3 am, and your sleep score was 82.
Am I recovered enough to run hard today?

Probably yes. Your resting heart rate is 48, two below your 30-day average, and last night's HRV was 62 ms, above your weekly baseline.
Is my resting heart rate creeping up?

A little. It averaged 49 in August and 52 over the last two weeks. The rise started the week you ran four days in a row, and it has eased since Sunday.
What was my fastest 5K this year?

23:41 on 14 September, a Saturday morning run. That's 4:44 per km on average, and your fourth kilometre was the quickest at 4:31.
Three promises, in plain words.
We never see your password
You sign in on Garmin's own page in its own window. The app keeps only the sign-in key Garmin hands back, in your computer's keychain.
Your data stays on your computer
It comes straight from Garmin to a file on your Mac or PC, and Claude reads it from there. There is no Fit AI Connect server in between.
Claude can only read
Claude can look up your data to answer you. It can't change, delete or upload anything.
