Anyone can count calories.
Tell Claude what you ate, in plain words, and Callie logs the whole label: calories, macros, fiber, eleven vitamins and minerals. Every day measured against targets set to your body.
Logging a meal should take 30 seconds.
Just tell Claude
Type what you ate the way you’d tell a friend. “Greek yogurt and walnuts.” No forms, no barcodes, no scales.
She breaks it down
Callie reads it, splits the meal into ingredients, and estimates calories and macros for each.
You watch the day add up
Every meal lands on your daily ledger: calories, macros, and what's still left before dinner.
Macros are the first three lines.
Every food you log carries its full profile. Callie tracks fifteen nutrients past calories and macros: fiber, eleven vitamins and minerals, and the ones to keep under a limit, like sodium and saturated fat. She weights them by how much of your day actually reported data, and only shows you what she can stand behind.
Cook once, log it for months.
Save anything you cook and log it by servings. Macros, fiber and every micronutrient scale to the portion on your plate. Already logged a meal worth keeping? Turn it into a recipe in one line.
Set to your body.
Protein at whatever grams per kilo you train on. A carb and fat split you choose. Micronutrient targets drawn from your age and sex rather than a generic chart. Set them once with Callie, and every day measures against them.
Add what only you eat.
Homemade granola, the local bakery loaf, your gym's protein shake. Define a food once with its portions and Callie logs two bars or half a loaf without you weighing a thing.
Real values from USDA FoodData Central and half a million scanned products, or your own foods.
A daily card you can screenshot: energy, macros, fiber, and which targets you hit.

I've deleted MyFitnessPal three times. Two months with Callie and I haven't missed a day, mostly because I'm in Claude all day for work anyway.
Turns out I was eating about 9 grams of fiber a day. Nobody tells you that. Callie did, so now there are lentils in my life.
I type 'big bowl of the leftover pasta' from the sofa and it's logged. That's the whole workflow.
