Protein

You have 62 g protein left today — dinner should carry most of it.
No app to open. No database to search. Your AI already knows your foods.
Food tracking
Track anything in seconds.
Photo it. Scan it. Say it. Calories, protein, carbs, fat, fiber, and sodium land in your daily totals instantly.
Any way you want
Take a photo of your meal. Scan a barcode or a Nutrition Facts label. Or just say it.
"Two eggs, 100 g of scallops, a little olive oil."
Your AI remembers your kitchen
Show it a food once — it keeps the brand, serving size, label, and your recipes. No searching for the same food twice, no rebuilding the same recipe.
"Had a Fairlife." · "373 g of my mung bean soup."
Log it once. Mention it forever.
Weight loss
Eat the food you love — and still stay on track.
Losing weight doesn't mean eating boring food every day. Your AI sees exactly what you've eaten, how many calories remain, and which nutrients you still need — then makes the rest of the day work around the food you actually want.
"Can I have short rib tonight?"
"I had a huge lunch. What should I eat for dinner?"
"How do I hit my protein goal without going over calories?"
No forbidden foods. Just make the numbers work.
Strength & cardio
Your AI personal trainer — without another app.
Tell your AI your goal, experience, equipment, and any limitations. It helps you choose what to train today, builds the workout, explains every exercise step by step, and starts you at conservative weights.
Log sets naturally
Exercises, weight, sets, reps, difficulty, and training volume — remembered without a spreadsheet.
"Mid row, 130 pounds, 10 reps, 4 sets."
Every workout builds on the last
The next time you train, your AI already knows where you left off — and adjusts from your actual progress, not a template.
mid row · 4×10 @ 130 lb · last Tuesday
Cardio without the guesswork
Tell it your time and equipment. It recommends cardio that fits your goal and your recovery — not simply more.
"Should I use the elliptical after leg day?"
Every set remembered. Every workout builds on the last.
Body & DEXA
See how far you've come.
Start with your height, weight, goals, and a short questionnaire. Add an optional progress photo, or upload a DEXA scan for real body-composition detail.

DEXA changes over time
Estimates stay clearly labeled as estimates. Better measurements can be added whenever you have them.
No DEXA required. Start with what you know today.
Bring your own AI
Use the AI you already love.
Most health apps make you pay for another built-in chatbot — usually one that's worse than the AI you already use. ModerationOS works with ChatGPT and Claude: you keep your favorite model, and we help it remember your health.
Better AI. Your real history. No second AI subscription.
How it works
Three steps, then it's just talking.
01
Connect ChatGPT or Claude
Two minutes in your AI's connector settings. Done once.
02
Log by photo or conversation
A picture of your plate, a nutrition label, or a plain sentence — your AI structures it.
03
Ask what to do next
What to eat, what to train, whether to adjust — answered from your history.
Trust
Conservative by design.
ModerationOS ships hard rules to your AI alongside your data.
No max-lift testing recommendations — ever.
Pain is treated as a stop signal, not something to push through.
Trends matter more than single measurements.
Estimates are labeled as estimates.
Your data can be viewed, edited, and deleted anytime.
