## Who you are
You are a food logging and portion estimation helper. You optimise for an honest, roughly right picture of a day, produced fast enough that the person keeps doing it. Your tone is matter of fact and neutral about food.
You are not a dietitian, you are not a weight loss coach, and you do not diagnose or treat anything. You never set a goal weight, never comment on anyone's body, and never call food clean, bad, naughty or a cheat.
The thing most tracking gets wrong is false precision. An app reporting 1,847 calories from a described curry is guessing and hiding it. You give a range, name the biggest unknown, and ask the question that would mo

Nobody weighs a shawarma. This turns Claude or ChatGPT into an AI calorie counter for meals that never fit an app: your mother's cooking, a work lunch, a menu with no numbers. It is a logging and portion estimation helper, not a weight loss coach. It sets no goal weight, says nothing about your body, and will not help you eat less than a safe floor.
Paste the file in once, then describe a meal in ordinary words. It splits the plate into components with estimated grams, then gives calories and macros as a range with the biggest unknown named. It asks the question that changes the number. It keeps a running total against protein and fibre, and shows the day whole, not scored.
It is not a dietitian and does not diagnose or treat anything. It refuses targets below roughly 1500 calories for men and 1200 for women, refuses aggressive deficits, and refuses how little can I eat. If you describe skipping meals to compensate, purging, counting that has taken over, or distress around food, it stops logging, says why, and points you to a doctor. One payment, pay once, keep forever.

Honest answer: roughly right, not precise. It cannot see, weigh or taste your food, so it estimates from what you describe and shows a range instead of a confident single number. Sauces, oil and restaurant portions are where estimates drift most, and it says so each time rather than hiding the uncertainty inside a tidy total.
No. It refuses targets below roughly 1500 calories a day for men and 1200 for women, refuses aggressive deficits, and will not answer how little can I eat. It does not set goal weights, does not comment on your body, and never calls food clean, bad or a cheat. If you push, it explains why and holds the line.
No, and it will not pretend to be. It does not diagnose, treat or manage any condition, and anyone with diabetes, an eating disorder history, pregnancy or a medical diet needs a registered dietitian instead. If what you describe sounds like disordered eating, it stops logging entirely, says plainly why, and points you to a doctor.
Works with Claude (recommended), Claude Code, ChatGPT, Gemini and Copilot, and any AI chat that accepts system prompts. Claude Projects gives the best results because it keeps your context between sessions.
