Your AI nutritionist. It knows how you train.
Send Claude or ChatGPT a photo of your plate or a line about lunch. Octos logs it, counts it against targets that follow your training and weight, and keeps your diet and allergies in every answer.

Works with your AI and your devices
Food logs die in a week. Octos keeps them easy.

Counting food by hand takes minutes per meal, so the log stops by Thursday.

Your target today is 2,150 kcal and 130 g of protein — there is a long ride on the plan. Let’s start with breakfast: what do you have at home?
Snap the plate. The rest is counted.
Your AI recognises the food and estimates the grams. Octos takes calories and macros from its food database and adds them to the day.
About 780 kcal and 48 g of protein. After three hours on the bike you are still 120 g short on carbs — add oats or rice to dinner.

One methodology, your rules on top.
Your targets come from a methodology, not a guess: energy from your body and training, protein by weight, carbs by load — checked as weekly averages.
Built on energy balance
Your base rate from your body, your training on top, adjusted by how your weight actually moves.
Calories or hand portions
Count in kcal and grams, or in palms and fists. Switch any time — your history converts too.
Rules come first
Allergies, diets and foods you skip are rules. Every answer respects them.
Or bring your own
Write your own methodology on the screen or with your AI. It replaces Octos’ one until you delete it.
Your weight, your training, your plate — in one place.
Weight comes from WHOOP or Apple Health, training load from your devices, meals from your AI. Your nutritionist sees all of it before it answers.
Weight toward your goal
The goal is a range with a date. You see the trend — and your nutritionist adjusts the plan to it.
One memory for every role.
Octos keeps what matters about you — facts, rules and documents — and every role works from it. Your coach knows what your nutritionist knows. Switch from ChatGPT to Claude and nothing is lost.

Questions
How do I log a meal?
Send a photo or a line to Claude or ChatGPT, or add it on the screen. Your AI recognises the food and estimates the grams; the numbers come from Octos’ food database.
Where do the calories come from?
From a food database built on open data, not from the model’s memory. You can add your own products and recipes.
Calories or portions?
Your choice. Count in kcal and grams, or in palms, fists and thumbs. Switch any time.
Does it know about my training?
Yes. Octos sees your sessions and load, so energy and carbs follow the day you are having.
Do I need to be technical to connect this?
No code, but a few steps. In Claude or ChatGPT you add Octos as a connector: paste its address in the settings, sign in to Octos and allow access. The step-by-step guides show every screen. If you get stuck, book a call and we’ll set it up with you.
Is this medical advice?
No. Octos helps you plan and track food. For a diet for a medical condition, an eating disorder or pregnancy, work with a doctor.
Your next meal is the first entry.
