About kcal.quest
Last updated: 25 August 2026
kcal.quest is built by one person who tests it on their own meals (Polish food included) and their own body before anything ships to others. If something is here, it is because it genuinely helps, not because it looks good on a slide.
The promise
Weight loss without the misery of weighing, counting and writing everything down. Photograph your plate and get honest numbers in seconds. Every feature should remove effort, not add it.
That is not an arbitrary test. Most people do not quit calorie counting because it fails to work; they quit because two weeks of weighing and typing is more than anyone wants to keep doing. If a new feature adds a step, it does not ship.
Honest by design
No invented stats, no fake testimonials. A photo is an estimate, not a kitchen scale, so every analysis says plainly how far off it might be. When the AI is unsure it asks a question rather than guessing and stating a number with a straight face. Nutrition labels, barcodes and weighed notes are the most accurate inputs, and they are described that way.
Where your data lives
Your journal, your weights and your progress photos sit in the browser on your device. There is no account, no server database and no tracking. A scan photo is sent to Anthropic's API for the analysis itself, because there is no way to read a plate without it, and it is stored on none of our servers. You can export a backup to a file or delete everything in one tap.
What is not here yet
There are no accounts, so there is no sync between your phone and your laptop. There are no payments, so everything is free right now, with a daily scan cap because every scan costs real money at the AI provider. Barcode scanning works only where the browser exposes it, which means Chrome on Android and on desktop. On an iPhone you photograph the label instead, which is more accurate than the barcode anyway.
Polish, not translated Polish
The app is built in Polish and English side by side. The Polish is written as Polish rather than run through a translator, and the food is treated the same way: pork cutlets, pierogi and yesterday's soup have to work as well as oatmeal and a salad.
