FAQ

What is the Pacelab Plugin for ChatGPT?
A full account connection inside ChatGPT. After signing in to Pacelab, ChatGPT can read your existing workouts, create new ones directly in your library, edit them, and see your training history.
How do I connect the Pacelab Plugin to ChatGPT?
Open the Pacelab Plugin from ChatGPT, sign in to your Pacelab account when prompted, and start describing workouts — ChatGPT builds, edits and saves them straight to your library.
Can I use ChatGPT without a Pacelab account?
Yes — the free Interval Builder GPT needs no account. It returns a share link you open in the app, but it can't read or change your existing library the way the Plugin can.
Is the Pacelab Plugin free?
Yes — the Pacelab Plugin and your Pacelab account are both free, no subscription. ChatGPT Plus is only required for the Custom GPT alternative, not the Plugin.

No — only the workout data the Plugin sends to our API. See the Privacy Policy and Terms.
Is there a version of this for Claude?
Yes — see Claude + MCP integration — same account, same capabilities.
