Use with ChatGPT #
There are two ways to use your Garmin data in ChatGPT: the Plugin and the Custom GPT. The Custom GPT version ends on November 30, 2026 — please use the Plugin. New features such as sending workouts are available only in the ChatGPT Plugin version and the Claude version (see How long can I keep using the Custom GPT version?). Both share the same account and Garmin connection, so if you move from the Custom GPT to the Plugin you still see the same data.
Plugin or Custom GPT?
