Connect ChatGPT or Claude
This guide walks you through connecting ChatGPT or Claude to your Assistant Coach account, so you can ask about your coaching data in plain language: a client's weight trend, how their training is going, whether they hit their protein, or help with this week's check-in reply.
The connection is for coaches only. Clients can't connect ChatGPT or Claude to their client app.
What it reads on your plan
- Free and Starter: Emma, your demo client, with 8 weeks of check-ins, a month of workouts and a week of meals. It's a free way to see what ChatGPT or Claude can do with coaching data before you use it with your own clients.
- Pro: all your clients.
If you upgrade to the Pro plan, the connection you already have reads all your real clients straight away. There's nothing to reconnect.
Before you start
You'll need:
- An Assistant Coach account, on any plan
- Claude on any plan, including the free plan, which allows one custom connector. Or ChatGPT on a paid plan
Both connect with the same link. You'll find it in Settings → Connected apps, under Your connection link, with a Copy button next to it.
Connecting Claude
- In Assistant Coach, go to Settings → Connected apps and click Copy next to your connection link.
- Open claude.ai and go to Customize → Connectors.
- Click + Add, then Add custom connector.
- Give it a name (for example "Assistant Coach"), paste your connection link, and click Continue.
- Leave the sign-in settings as they are and click Add.
- Click Connect.
- An Assistant Coach page opens. Sign in if you're asked to, check what Claude will read, and click Allow.
- You're connected. Go back to Claude and ask your first question.
- When Claude first uses Assistant Coach in a chat, it asks your permission for each kind of data. Choose Always allow, so it doesn't ask again.
On a Claude Team or Enterprise plan, only your organisation's owner can add connectors, so ask them to add it.
Connecting ChatGPT
- In Assistant Coach, go to Settings → Connected apps and click Copy next to your connection link.
- Open chatgpt.com and go to Plugins → Add → Add custom MCP server.
- Name it "Assistant Coach", paste your connection link, and leave Authentication on OAuth.
- Tick I understand and want to continue, then click Create as a plugin.
- Click Connect Assistant Coach.
- An Assistant Coach page opens. Sign in if you're asked to, check what ChatGPT will read, and click Allow.
- You're connected. In a new chat, type @, choose Assistant Coach, then ask your question.
What the approval page shows
Before anything is shared, Assistant Coach shows you exactly what ChatGPT or Claude will be able to read. On Free and Starter it says it will read "for your demo client, Emma", with a line saying that on the Pro plan, the same connection reads all your clients. On Pro it says "for all your clients". Nothing is shared until you click Allow, and you can disconnect any time.
Once you've clicked Allow, Settings → Connected apps shows the app as connected within a few seconds, without a reload.
Using the connection
Once connected, you can ask ChatGPT or Claude questions about your coaching data in plain language. It looks up the answers in Assistant Coach for you.
What ChatGPT or Claude can read
For each client it can read (on Free and Starter, that's Emma):
- Their profile and goals
- Check-ins, including progress photos, your responses and your client's replies
- Workout and meal plans
- Logged workouts, with every set and the client's effort rating
- Food logs, with each day's calories and macros
- Weigh-ins and tape measurements
- Habits
- Sessions and session packs
It can also read your private notes and your exercise library. It doesn't see payments, the medical questions on your intake form, meal photos, or workout photos and videos.
Your clients' notes and feedback are shared as they wrote them, so they may include health details. If you disconnect, ChatGPT or Claude can't read anything new, but what it has already read stays in that chat.
Questions to try on Emma
These are the same five questions you'll see in Settings → Connected apps, each with a Copy button:
"Chart Emma's weight and waist over the last 8 weeks. What's the trend?"
"Which of Emma's lifts went up this month, and where is the effort climbing?"
"How close was Emma to the protein target each day last week?"
"Emma's energy has dropped. What in the sleep, habits and training data might explain it?"
"Emma says work is hectic. Help me write this week's check-in reply."
With Pro: questions about all your clients
On Pro, Settings → Connected apps shows these five, each with a Copy button:
"Give me a quick summary of how each of my clients is doing this week."
"Whose weight has moved the most over the last month, and who has stalled?"
"Whose lifts went up this month, and where is the effort climbing?"
"Which clients mentioned low energy, poor sleep or stress in their recent check-ins?"
"Help me write a reply to my most recent check-in."
More you can ask:
Client overview:
"Give me a summary of all my active clients and their current status"
Check-in analysis:
"What did Sarah report in her last check-in? How does it compare to the previous week?"
Trend spotting:
"Which clients have been losing weight consistently over the past month?"
Program review:
"What's in David's current workout plan? How many sessions per week?"
Planning help:
"I need to update Maria's meal plan. What are her current macros and what did she say about hunger in her last check-in?"
Cross-client insights:
"Which clients mentioned energy issues or fatigue in their recent check-ins?"
Training progress:
"Which of David's lifts went up over the last four weeks, and where is his effort climbing at the same weight?"
Food logs:
"How close was Sarah to her protein target each day last week?"
Weigh-ins:
"Chart Maria's weigh-ins for the last eight weeks and give me the weekly averages."
Habits:
"How consistent has Sarah been with her water habit this month?"
Sessions:
"Who do I see this week, and whose session pack is about to run out?"
The more specific your question, the more useful the answer. But even broad questions like "How are my clients doing?" can give you a useful snapshot. A good habit: ask it to describe what the data shows first ("What changed this month?"), then decide what to change in the plan yourself.
Managing connections
Viewing connected apps
Go to Settings → Connected apps to see the apps currently connected to your account. Each shows:
- The app name and icon
- When it was connected
- A Disconnect button
If an app says Approved today, still connecting, you clicked Allow but ChatGPT or Claude hasn't finished connecting yet. It usually clears in a few seconds. If it stays, click Disconnect and connect again from the start.
Disconnecting an app
If you want to revoke access:
- Go to Settings → Connected apps
- Click Disconnect next to the app
- Confirm the disconnection
Access is revoked immediately. ChatGPT or Claude will no longer be able to read your coaching data. You can reconnect anytime by going through the setup process again.
Frequently asked questions
Does this cost extra? No. You can connect ChatGPT or Claude on every Assistant Coach plan. On Free and Starter it reads your demo client, Emma; on Pro it reads all your clients. Claude's free plan allows one custom connector, which is all you need. ChatGPT needs a paid ChatGPT plan.
Why can't Claude see my other clients? On Free and Starter, ChatGPT and Claude read your demo client, Emma, so you can try it on real-looking coaching data. Ask about your other clients and it explains that Emma is the one client it can read on your plan, with a link to Pro. It never sees your other clients' names or data. On Pro, the same connection reads all your clients, with nothing to reconnect.
What if I deleted Emma? On Free and Starter, connecting brings Emma back. If you delete Emma after connecting, ChatGPT or Claude will tell you Emma isn't in your account any more: disconnect in Settings and connect again, and Emma comes back.
Can ChatGPT or Claude change my data? No. The connection is strictly read-only. They can view your data but cannot create, edit, or delete anything — not clients, not plans, not responses.
Can other coaches see my data through their own connection? No. Each connection is scoped to your account only. Your clients' data is only accessible through your authenticated connection.
What if I change my password? Your ChatGPT or Claude connection stays active. It uses separate authentication tokens that aren't tied to your password.
Can my clients connect ChatGPT or Claude? No. The connection is for coaches only.
