About DietSem

Take a photo of your plate and DietSem's AI recognises the dish, estimates the calories and logs the meal in your diary with a short practical tip. The Today dashboard shows calories against your target, meals, water and steps in one place, and the reports show calorie balance, water intake and a weight curve over time. Water, steps and exercise are logged by hand with quick-add buttons, and 16 activity types come with automatic calorie estimates.

Planning is where the AI does the most work. The weekly plan builds a seven-day menu from your health conditions, food preferences and meal pattern, intermittent fasting included. Fridge Diet takes the ingredients you have and returns five healthy recipes with calories, protein and preparation steps. When motivation dips, the AI coach answers with empathy and one small, doable next step.

New accounts receive three AI photo scans, and more come from daily check-ins and optional reward videos. Scan packs, plan credits and DietSem PRO, monthly or yearly with a seven-day trial or as a lifetime purchase, unlock everyday use of the AI features. An account and an internet connection are required. DietSem offers general wellness guidance and is not a substitute for medical advice.

Who it is for

Adults who want help tracking what they eat, planning balanced meals and staying motivated, without weighing every ingredient.
