Read-only · your data stays yours
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
Connect your Garmin
Sign in to garmlink and link your Garmin Connect account. We sync your history and keep it fresh.
Paste one URL
Add garmlink as a custom connector in Claude or ChatGPT — one URL, an OAuth approval, done.
Ask anything
“Am I ready for my half marathon?” “How did I sleep this week?” Your AI answers from your real data.
Ask AI
An AI coach, built in
No setup, no connector — the dashboard has its own assistant.
Open the dashboard, hit “✦ Ask 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.
