How to connect ChatGPT to Jotly

You can connect ChatGPT to Jotly and manage your size guides by chatting with it. Once connected, you can ask ChatGPT to create a size guide, update one, change which products it shows on, or find out why a size guide is not showing on your store. This guide shows you how to connect it. It takes about 3 minutes.

Heads up

Connecting an AI assistant is available on the Jotly Enterprise plan.

Before you start

  • Keep the Jotly app open in one browser tab. You will copy your store domain and a connect code from it in Step 4
  • Sign in to chatgpt.com in another tab

Step 1: Add a custom MCP server in ChatGPT

Open this page in your browser: https://chatgpt.com/plugins. In the top right corner, click the Add button, then click on Add custom MCP server.

Step 2: Fill in the details

  1. In the Name field, enter Jotly Size Guides
  2. Keep the connection type set to Server URL
  3. In the connection field, paste this URL: https://sizechart.jotlyapps.com/api/mcp
  4. Keep Authentication set to OAuth
  5. Tick the checkbox to confirm
  6. Click Continue
Note

You can also copy the name and the URL from the Jotly app. Open AI Assistants, click Connect next to ChatGPT, and use the Copy buttons on that page.

Step 3: Confirm

ChatGPT shows a confirmation window. Click Continue.

A Jotly page opens and asks for your store domain and a connect code. Keep this page open, you will fill it in after the next step.

Step 4: Get your store domain and connect code from Jotly

Go to the tab where the Jotly app is open.

  1. Click on AI Assistants in the Jotly menu
  2. Click Connect next to ChatGPT
  3. Scroll to the Approve access step. Your store domain is shown there
  4. Click Generate connect code. A code appears below your store domain
Note

The connect code works one time and expires after 10 minutes. If it expires before you use it, click Generate a new code to get a fresh one.

Step 5: Enter the details and allow access

Go back to the Jotly page that ChatGPT opened in Step 3.

  1. Paste your store domain in the Store domain field
  2. Paste the connect code in the Connect code field
  3. Click Allow access
Works

That's it. ChatGPT is now connected to Jotly. Refresh the AI Assistants page in Jotly and you will see ChatGPT under Connected.

What you can ask ChatGPT

Start a new chat in ChatGPT and ask in your own words. Here are a few examples:

  • "List my size guides"
  • "Create a size guide for men's t-shirts with sizes S to XL"
  • "Turn off unit conversion in my jeans size guide"
  • "Show the shirts size guide on all products with the tag summer"
  • "Add a how to measure section to all my size guides"
  • "Why is my size guide not showing on my store?"
Note

ChatGPT can create and update your size guides, but it can never delete one. To delete a size guide, use the Jotly app.

Good to know

  • A connection works for 30 days. After that, open AI Assistants in Jotly and click Renew next to it. You do not need to set anything up again
  • To remove access, open AI Assistants in Jotly, open ChatGPT under Connected and click Disconnect
  • Each person on your team can connect their own ChatGPT account. Every connection shows who connected it

Something not working?

  • ChatGPT shows an error when adding the server: check that the URL has no extra spaces and that Authentication is set to OAuth
  • The connect code is not accepted: check that the store domain matches the one shown in Jotly. A code works once and expires after 10 minutes, so generate a new one and try again
  • ChatGPT does not use Jotly in a chat: make sure Jotly Size Guides is selected for that chat
  • ChatGPT does not see a new Jotly feature: open the Jotly connection in ChatGPT and refresh it
