About Olivka
Last updated: August 22, 2026
Builds Olivka end to end — the vision pipeline, the nutrition-database matching, and the evaluation loop that re-checks logged meals against reference models.
Runs the company side of Olivka — what gets built next, who it is for, and the commercial decisions behind it.
Olivka is an AI calorie counter that lives in the chat apps you already use. This page says who builds it, how it works underneath, and — the part most product pages skip — where its limits are. If you are deciding whether to trust a calorie estimate that arrives in a chat window, that is the information you actually need.
Who builds Olivka
Olivka has two co-founders, Gabriel Kurowski and Franciszek Mysłek, and is a product of Deveji sp. z o.o., a company registered in Poland (KRS 0001054053, NIP 9522245188). Gabriel writes the code that reads your photo, chooses which nutrition databases an ingredient is matched against, and runs the evaluation loop that checks whether the resulting numbers hold up. There is no separate content team writing about a system somebody else built.
That matters for a page like this one. When Olivka tells you a meal is 620 kcal, the explanation of where that figure came from is written by the person who built the thing that produced it — and it can be checked against the methodology page, which sets out the databases and the error bars in detail.
How Olivka counts a meal
You send a meal the way that suits you: a photo, a voice note, or a line of text. A vision model reads the photo first and describes what is on the plate — the dish, its ingredients, and the portion sizes. Each ingredient is then matched against real nutrition databases: USDA FoodData Central and Open Food Facts, with a web lookup for restaurant dishes and branded products that public databases handle poorly.
Your calories and macros are calculated from those matched entries rather than estimated by a language model guessing at a number. You get back an itemised meal card with Confirm and Edit buttons, so nothing enters your log before you have seen it, along with a running total for the day. When a meal is genuinely ambiguous — a large portion or a small one — Olivka asks rather than picking one silently.
How the numbers get checked
Estimating calories from a photograph is a job with a real error rate, so treating it as solved would be the wrong posture. On a schedule, a sample of meals that have already been logged is re-run through the pipeline and judged by a separate reference model, and estimates that drift materially from the original are flagged for review. It is a way of catching systematic problems — a category of food consistently read wrong, a database match that keeps landing on the wrong entry — rather than arguing about any single meal.
What that process cannot do is make a calorie estimate exact, and we do not claim it does. Printed nutrition labels are themselves legally permitted to be off by a substantial margin, which sets a floor on the precision available to any calorie counter, app or not. The methodology page states those tolerances with sources.
What Olivka is not
Olivka does not write you a diet. She does not calculate a calorie target on your behalf, does not build meal plans, and does not tell you what to eat next. She asks which of three goals you are working toward — losing weight, maintaining, or building muscle — and adjusts what she pays attention to, and beyond that her job is to count honestly and keep the daily total in front of you. If you want a target number, the free calculators on this site work one out and show the equation they used.
Olivka is also not medical advice and is not a substitute for a dietitian or a doctor, particularly if you are managing a health condition, are pregnant, or have a history of disordered eating. It is a tool for counting food, and it is worth being clear about the difference.
