Claude

Connectors work on every Claude plan, including Free, which allows one custom connector. Set it up on the web or in the desktop app; it then works on your phone too.

  1. In Claude (web, desktop or app), open Customize → Connectors and choose “Add custom connector”.
  2. Enter the server address shown below.
  3. Sign in to YumiFit and approve access. You can then return to the chat.

ChatGPT

Whether you can add your own connector depends on your ChatGPT plan and country, and OpenAI changes this from time to time. If your plan doesn’t offer it, use Claude or the web app for now.

  1. In ChatGPT, open the apps/connectors settings and add a new connector.
  2. Enter the server address shown below.
  3. Sign in to YumiFit and approve access. You can then return to the chat.

Your first message

Try: “Log in YumiFit: 2 eggs and toast.” Your assistant tells you what it saved.

You can disconnect in YumiFit settings or in your assistant at any time.

The connector isn’t listed in the ChatGPT or Claude directories yet. We’ll confirm the ChatGPT steps once we’ve tested them in ChatGPT.
