AI is pretty good in translating "bread with butter" into realistic calorie and nutrient values by evaluating typical portions and knowing the numbers. It's even pretty good at guessing from photos. I wanted a tool for myself, because I simply didn't like other trackers or their price. This one starts free, with all features available. The only reason there's a paid plan is because I need to cap the free usage somewhere, coz I actually pay for every single AI call made under the hood. But for a price of coffee, you can have fully unlimited version. I use this every day and am fairly happy with it so far.
