What's on your plate? Show Mangi.

Typing in every ingredient is why people stop tracking. Take a photo of your meal and see what the Mango Bites AI reads from it, the same way the app does it.

Take a photo of your meal Take a photo

Short answer

Yes, AI can estimate calories from a photo. It recognises the foods, estimates the portion from the plate and the size of everything around it, and looks up the nutrients. The weak spot is portion size and hidden fat like oil and sauces, the same thing people get wrong by eye, so a photo is best for everyday tracking rather than a lab-grade weigh-in.

What this page cannot do

One photo shows you a meal. The app shows you the day.

A single scan is a number. Mango Bites keeps every meal you photograph, adds them up against your own targets and tells you what to change at the next one, so the photo you just took turns into a habit.

Get a better reading

Shoot from above, in good light

A top-down photo shows the whole plate and its size. Side angles hide half of the food and make portions look smaller.

Keep the plate and cutlery in frame

Plates, forks and glasses are the ruler the AI uses to judge how big the portion is.

Mention the hidden stuff

Oil, butter and creamy sauces are invisible in a photo and carry a lot of calories. In the app you can add them in one tap.

How this is worked out

Recognise, measure, look up, score

photo → foods + portions (g) → nutrients per 100 g × grams → calories, macros, fiber, health score

The photo goes to the same vision model and instructions the Mango Bites app uses. It names each part of the dish, estimates its weight from the plate and objects around it, and works out calories, protein, carbs, fat and fiber per portion from standard nutrient tables such as USDA FoodData Central.

The health score (0 to 100) weighs the meal's balance, fiber, sugar and processing for a general adult profile. In the app it is scored against your own goal and diet.

Research on image-based dietary assessment finds that recognising foods is now reliable and that portion size is the main source of error, for AI and for people estimating by eye. That is why the tips above matter.

What a scan tells you

Everything below comes from one photo, with no typing.

Fields returned by a meal scan
You get	What it means
Calories	Energy in the portion on the plate, not per 100 g
Protein, carbs, fat	Grams of each, and their share of the calories
Fiber	Grams in the meal, the nutrient most people fall short on
Ingredients	Each part of the dish with its estimated weight
Health score	0 to 100, how well the meal is balanced
Mangi's reaction	A one-line take on the meal, in your language

Questions people ask

Can AI really count calories from a photo?

Yes. Modern vision models recognise foods reliably and estimate portion size from the plate and objects around it, then calculate nutrients from food databases. It is accurate enough for day-to-day tracking, which is what most people need.

How accurate is a calorie estimate from a photo?

Food recognition is the easy part; portion size and hidden fats like oil are where estimates drift, for AI and for trained people estimating by eye alike. A clear top-down photo with the whole plate in view gives the best result.

Is this free? Why only one photo a day?

The demo is free and needs no account. Every scan runs a paid AI model, so the web demo is limited to one photo per person per day. The Mango Bites app is free to download and is built for scanning every meal.

Do you keep my photo?

No. The photo is sent to analyse the meal and is not stored or added to any account. The result stays in your browser so you can see it again today.

What is the best app to count calories with a photo?

Look for one that gives you macros and fiber, not just calories, lets you fix a portion in a tap, and keeps you coming back. Mango Bites does all three and adds a health score and Mangi's tips for each meal.

Does it work with drinks, snacks and restaurant meals?

Yes. It reads home-cooked plates, packaged snacks, drinks and restaurant dishes. For mixed dishes it lists the main components with an estimated weight for each.

This is an estimate, not medical advice. Formulas like these describe averages, and you are a person rather than an average. Medication, thyroid conditions, pregnancy, breastfeeding and a history of disordered eating all move these numbers. Talk to a doctor or a registered dietitian before making a big change.
