Text Your AI Coach: ChatGPT Dots, iMessage, and TrainingDojo

The best time to ask about your training is rarely when you are sitting at a computer. It is at 5:40 in the morning when your legs feel flat, or at lunch when your afternoon just disappeared and you have 45 minutes instead of 90.

ChatGPT dots make that possible. A dot is an always-on agent in ChatGPT, and you can now text it. Connect TrainingDojo and your dot can read your actual training calendar and move workouts, right from your Messages app.

What This Looks Like

Here is an example of the kind of exchange you can have.

You: Only got 5 hours of sleep. What's on today and should I change it?

Dot: You have 3 x 12 min threshold on the plan. Your HRV is down and
last night was your shortest sleep this week. I'd swap it for 60 min
easy and move the threshold session to Thursday, which is open.
Want me to make that change?

You: Yes

Dot: Done. Today is now 60 min easy, and threshold is on Thursday.

Before You Start: Availability*

This is new, and it is limited. As of October 30, 2026:

• Your first dot is included with ChatGPT Pro and Business Premium, and access is rolling out gradually.
• Texting a dot is rolling out in beta to ChatGPT Pro users in the U.S., over iMessage or RCS.
• Texting is not available in Business or Enterprise workspaces.
• Your dot can only text you, and only you can text it.

*Availability depends on your AI provider, plan, and region, and it is changing quickly. Check OpenAI’s current documentation for the latest.

How to Set It Up

1. Connect your training platform. Connect TrainingPeaks or Intervals.icu in TrainingDojo.
2. Connect TrainingDojo to ChatGPT. Follow the ChatGPT setup guide. Connect on Free to read your training. Moving or changing workouts requires Pro or Coach.
3. Turn on texting. Open your dot’s profile in ChatGPT and turn on texting. It shares the same memory and plugins as your dot in the app.
4. Try a read-only question first. Text: “What’s my workout today?” Once that works, try a change.

Things to Text For Your Own Training

What's on my calendar this week, and how does it look against last week?

I only have 45 minutes today. What should I do instead?

My knee is sore. Make the next two days easy and show me the change first.

How did Saturday's long ride compare to the plan?

I'm traveling Thursday to Sunday. Rework the week around that.

If You Are a Coach

The same setup works from a TrainingPeaks coach account. You can check on an athlete between sessions, or handle a schedule change from your phone without opening a laptop.

How did Maya's week go? Anything I should worry about?

Theo just told me Thursday is out. What are the options for moving
the key session? Don't change anything yet.

Move it to Friday and leave the rest of the week alone.

Remember that your AI provider sees whatever your assistant reads, including athlete data. Review your provider’s data settings before you use this with athletes. See how TrainingDojo handles coach-managed athlete data.

Which Tools Your Dot Uses

• get_upcoming_workouts reads the calendar and finds workouts to change.
• get_wellness reads sleep, HRV, and fatigue when they are recorded.
• list_recent_activities and get_activity_detail review what you completed.
• update_platform_workout moves or changes a workout.

Stay in Charge of Changes

Tell your dot how you want this to work. A simple rule goes a long way: “Show me what will change and wait for my yes before you update my calendar.” TrainingDojo never changes a plan on its own. Changes happen through your AI, and your AI app controls when it asks.

Not on ChatGPT Pro?

You can get most of this from a normal chat today. Connect Claude or ChatGPT to TrainingDojo and use the mobile app. In Claude, connectors work on mobile, and you get a notification on your phone when a task finishes or needs you.
