Track your meals.
Just text Marco.

Marco is a text-based macro tracker. Text what you ate in plain English and Marco logs calories, protein, carbs, and fat using USDA-backed food data, then replies with your macros and daily progress in the same thread.

Text Marco what you ate — for example, "eggs and toast for breakfast" or "chipotle burrito with chicken." Marco uses AI to match your meal to nutrition data, logs it to your account, and replies with a summary. Once you're off the waitlist, ask anytime for your daily totals or progress toward your goal.

After you join the waitlist, add Marco's number in iMessage and text what you ate — for example, "chicken burrito for lunch." Marco replies in the same thread with calories, protein, carbs, and fat for that meal, plus your running total for the day. Ask anytime for a full daily summary. No separate app to open.

MyFitnessPal requires opening an app, searching a food database, and adjusting servings for every item. Marco skips that — you text one sentence and Marco handles the matching. Marco is built for people who want nutrition tracking that fits into real life, not another app to maintain.

Cal AI estimates calories from a photo, but a picture cannot capture everything that matters. It cannot tell whether you used low-fat or full-fat cheese, diet or regular soda, which brand you bought, or which flavor you picked — details that can swing a meal by hundreds of calories. Marco works from what you say in plain English, so you can include those specifics. When something is unclear, Marco asks instead of guessing from a snapshot.

You could ask ChatGPT for calorie estimates, but it is not built for nutrition tracking. Marco matches what you say to verified USDA food data — not AI guesses — so what gets logged reflects real nutrition values. Marco is designed to map your words to the right foods and portions, avoids hallucinated foods or numbers, and saves every meal to a proper database tied to your account. Your history builds over time instead of getting lost in a chat thread, and your data is stored securely for tracking — not mixed into a general-purpose AI conversation.

Yes. Every meal you log is saved to a structured database with snapshot nutrition — not kept loose in an AI context window. That means you can ask Marco for today's totals, yesterday's meals, or progress toward your goals weeks later. ChatGPT forgets earlier messages as conversations grow; Marco keeps a persistent log you can rely on over time.

No. Marco does not invent foods or make up calorie counts. When you describe a meal, Marco matches it against verified food sources like USDA FoodData Central and snapshots the nutrition at log time. If something is ambiguous, Marco asks a clarifying question instead of guessing — which is a common problem when using general chatbots for meal tracking.

No app download required. Marco works through iMessage, SMS, and RCS — the messaging apps already on your phone. Text TRACK to join the waitlist and get early access.
