Frequently asked questions
How do I count calories from a photo?
Open nodiet.ai, tap the camera and take a photo of your plate. AI recognizes the foods, estimates the portion size and counts macros and fiber for each ingredient, usually within seconds. No photo? Describe the meal in text or by voice.
How accurate is AI at counting macros from a photo?
Accuracy depends on how clearly the dish is visible: AI estimates the portion from the photo and may miss hidden ingredients such as oil, sauce or sugar. That is why results are broken down by ingredient — you can fix any item, change the portion weight or add what the photo does not show.
Is nodiet.ai free?
Yes, the core features are free: every way to log food, the diary, goals, the calorie calculator, water, weight and reminders. The free plan has limits on AI requests, voice input and PDF reports. Pro removes those limits; prices are shown in your app store.
Can I use it without signing up?
Yes. Install the app and start logging food right away — no account needed. You can create one later, for example to keep your diary when you switch phones; all your entries are kept.
Which devices does nodiet.ai work on?
On iPhone (App Store), Android (Google Play) and in the browser at app.nodiet.ai.
How is my daily calorie goal calculated?
With the Mifflin–St Jeor equation: first your basal metabolic rate is calculated from sex, age, height and weight, then multiplied by an activity factor and adjusted for your goal: −15% to lose weight, +15% to gain. You can try it in the calorie calculator on this site.
How is nodiet.ai different from FatSecret and YAZIO?
In FatSecret and YAZIO you usually search a food database and log items by hand. In nodiet.ai a photo, a short text or a voice note is enough — AI calculates the macros, and the assistant answers nutrition questions. You can start for free without signing up.
Can I export my food diary?
Yes, you can export your diary to PDF, for example to share with a doctor, dietitian or coach. The free plan includes one report a week; Pro has no limit.
How do I cancel my subscription?
Anytime: in App Store or Google Play settings if you subscribed there, or in your nodiet.ai profile if you paid in the browser. We send a reminder 2 days before each charge.
Is my data safe?
Yes. Your data travels over an encrypted connection and is used to run the app — to recognize food and do the math. We never sell it. We use anonymized analytics to improve the app; see the privacy policy for details.
