Type What You Ate. Get Calories Instantly.

Most calorie counters make you search a database, scan a barcode, or tap through endless menus just to log a sandwich. This estimator does the opposite: describe your meal the way you'd say it out loud — "two eggs, a slice of toast and a banana" — and get an instant calorie and macro breakdown. No account, no manual entry, no friction.

It's the fastest way to sanity-check a meal before you eat it, settle a "how many calories is this?" debate, or see roughly where your day is landing.

How the Estimator Works

When you type a meal, the tool parses each food and quantity ("2 eggs", "1 cup rice", "150g chicken") and matches it against a database of common foods with typical portion sizes and USDA-style nutrition values. It adds everything up and shows you total calories plus protein, carbs, and fat — with a per-item breakdown so you can see what's driving the numbers.

It understands plain-language amounts (a, two, half, a dozen), household servings (slice, cup, scoop, bowl), and weights (grams and ounces). Separate foods with commas or the words "and" / "with".

How Accurate Is It?

This is a directional estimate, not a lab measurement. It assumes standard portion sizes and average recipes, so a heaping bowl or a restaurant version can run higher. That's exactly the gap Bento Bunny's app closes: instead of guessing portions, its AI looks at a photo of your actual plate (or reads a sentence you type) and estimates the real portions and ingredients for you — far more accurately, in seconds. You can also scan a barcode for packaged foods.

Why Effortless Logging Matters

The single biggest reason people quit calorie tracking is the effort of logging. Studies consistently show people underestimate intake by 30–50%, and the more taps it takes to log, the sooner they stop. Removing the friction — type it, photograph it, or scan it — is what makes tracking a habit you actually keep. Try the estimator above, then let Bento Bunny do it automatically.

Frequently Asked Questions

How does the AI calorie estimator work?
You type your meal in plain English — for example, 'grilled chicken breast with a cup of rice and broccoli'. The tool parses each food and quantity, matches it against a database of common foods and typical serving sizes, and sums the calories, protein, carbs, and fat. You get a total plus a per-item breakdown instantly, with no account or manual logging.
Is the calorie estimator free?
Yes, completely free with no sign-up. The Bento Bunny app — which estimates calories automatically from a photo of your meal or a sentence you type — is also free during the iOS beta.
How accurate are the calorie estimates?
It's a directional estimate based on standard portion sizes and average recipes, so real meals can vary, especially restaurant portions. For accurate, portion-aware results, Bento Bunny's app uses AI to read a photo of your actual plate (or a typed description) and estimate the real portions for you.
Can I estimate calories without taking a photo?
Yes. This tool works entirely from text — just type what you ate. In the Bento Bunny app you can log the same way (type a sentence), snap a photo, or scan a barcode, whichever is fastest in the moment.
What foods does it recognise?
It covers dozens of common foods across breakfast items, proteins, grains, legumes, fruits, vegetables, dairy, snacks, drinks, and popular meals like pizza, burgers, and burritos. If it can't match something, it tells you — and the full Bento Bunny app recognises far more from a photo.
