Use with ChatGPT #
There are two ways to use your Garmin data in ChatGPT: the Plugin and the Custom GPT. Both work on every plan, including Free. They share the same account and Garmin connection, so you can switch later and still see the same data.
Plugin or Custom GPT?
Available data by connection method #
Available data differs by connection method (on the Basic plan).
| Data | Plugin (v2) | Custom GPT |
|---|---|---|
| Daily wellness (steps, heart rate, sleep, stress, HRV) | ✓ | ✓ |
| Activity list (distance, duration, heart rate) | ✓ | ✓ |
| Detailed workout analysis (pace breakdown, lap splits, HR drift) | ✓ | ✓ |
| Device-recorded FIT metrics (Training Effect, time in zones, Normalized Power) New (August 2026) |
✓※2 | ✓※2 |
| Long-term trends (weekly comparisons) | ✓※1 | ✓ |
| Weight & body composition (body fat %, muscle mass) | ✓ | ✓ |
| Menstrual cycle data | — | ✓ |
| Data refresh (recover missed syncs) | ✓ | ✓ |
※1 On the Plugin, the AI may suggest up to 90-day windows until the next update (v3.0.0) — but you can access up to 5 years by explicitly asking for a longer period (e.g., “show the past year”).
※2 Activities synced on or after August 14, 2026 (Basic and above). Normalized Power and power zones require a power-capable device. See the FAQ for details.
