CONNECT CHATGPT
ChatGPT reads your training. Tally logs every set.
ChatGPT reads your training history. On Business, Enterprise and Edu plans, it can also write planned workouts and log, change or delete finished workouts when you ask. You can undo each change for 7 days.
You are on a phone or tablet. Setting up ChatGPT needs a computer, so do this in two parts.

What ChatGPT can do
- Read your training history, progress and planned days
- On Business, Enterprise and Edu plans: plan, change, move or skip planned days
- On those plans: log, change or delete finished workouts when you ask. You can undo each change for 7 days.
If something goes wrong
- I cannot find developer mode.
- Use chatgpt.com in a browser. MCP apps do not work in the ChatGPT phone app. On Business, only admins can use developer mode.
- ChatGPT cannot add workouts.
- On Pro, MCP apps are read only. On Business, Enterprise and Edu plans, ChatGPT can also write planned workouts and log, change or delete finished workouts.
- The agent sees no workouts.
- Sign in with the same method you use in the Tally app. Apple, Google and email sign-ins are separate accounts.
- The server address does not work.
- Use https://mcp.tallyworkout.app/api/mcp. The address tallyworkout.app is the website, not the API.
- Steps not working?
