Mind of Matt
Mind of Matt — only with Team 80/20
3 million words. 400 articles. 30 books. One coach.
Mind of Matt is the most highly trained AI coach in existence. It has learned and absorbed 3 million words — more than 30 published books and 400 articles — and every one of those words is the work of one human: endurance coach and author Matt Fitzgerald. That gives Mind of Matt a clear perspective, a consistent voice, and a coherent philosophy of endurance coaching that other chatbots lack. And it doesn’t coach in the abstract: before every answer, Mind of Matt reads your TrainingPeaks calendar — the training you’ve done and the week you have planned.

How does Mind of Matt use my TrainingPeaks data?
Before it writes or answers anything, Mind of Matt reads your TrainingPeaks calendar — the workouts you’ve completed and the sessions you have planned.

And it grounds every answer in your actual TrainingPeaks calendar.
What languages does Mind of Matt support?
