Setup

Set up Gutlog in one step

Paste this into ChatGPT, Claude or your coding agent. It reads the instructions, works out which app it is in, and either connects itself or gives you the exact clicks. Then it logs your first meal.

Paste into your assistant

Set up Gutlog for me: read https://getgutlog.com/setup.md and follow it.

Free to start, no card. You sign in once in your browser; there is no key to copy. The instructions your assistant reads are at /setup.md.

Or do it yourself

Pick your app. Every step, the URL to paste and a one-click link where the app has one.

Until the Gutlog app is listed in ChatGPT's app directory, add it as a connector in developer mode, on the web.
