Good to know

Meal logging in ChatGPT is text only. Your TrueCal plan and your access to ChatGPT are separate. Open the listing to check availability for your account and workspace.1

Free TrueCal accounts get 3 introductory AI meal logs in ChatGPT for the life of the account. An attempt counts once processing starts, even if no meal is saved. After those logs, AI logging needs Pro.1

Accounts created in ChatGPT get no complimentary Pro trial. Free accounts show calories but not macros. Nutrition results are estimates, so check the saved foods and portions.1
