Your Garmin data, in Claude and ChatGPT.

Connect once. Then ask your AI anything about your training, sleep, HRV and recovery — answered from your real Garmin data, not guesses.

How it works

01

Connect your Garmin

Sign in to garmlink, then sign in to Garmin Connect with your email and password. The password is used once and never stored — only the encrypted tokens it returns. We sync your history and keep it fresh.

02

Paste one URL

Add garmlink as a custom connector in Claude or ChatGPT — one URL, an OAuth approval, done.

03

Ask anything

“Am I ready for my half marathon?” “How did I sleep this week?” Your AI answers from your real data.

Connect garmlink to your AI assistant

All assistants and code tools →

Ask Internal AI

An AI coach, built in

No setup, no connector — the dashboard has its own assistant.

Open the dashboard, hit “✦ Ask Internal AI”, and ask anything about your training, sleep or recovery. The assistant reads your real synced Garmin data through the same tools the Claude and ChatGPT connectors use — nothing to configure, answers grounded in your numbers.

• Grounded in your data — every answer cites the dates and values it used.
• Read-only — the assistant can look, never change anything.
• Prefer your own AI? Connect Claude or ChatGPT to the same data anytime. Try it on your dashboard

Everything your watch records

garmlink keeps the raw data — the original activity files, the full time series — so your AI reasons from the source.

Every run, ride, swim, hike — summaries, splits, zones.

Time series

Heart rate, pace, power, altitude, cadence — the raw 1 Hz record.

Sleep & stages

Score, deep/light/REM, SpO2, respiration, skin temperature.

Overnight HRV

Nightly values and 7-day baseline status.

Stress & Body Battery

All-day timelines, charge and drain events.

Training status

Load, readiness, VO2max, endurance & hill score.

Race predictions

5K to marathon estimates, tracked over time.

Personal records & gear

PRs by sport, shoes and bikes with mileage.

Ask it like you'd ask a coach

Am I ready for my half marathon in 6 weeks?

Summarize my training load over the last month.

How has my HRV trended versus my sleep?

Which of my runs had the best efficiency?
