What's Inside

Every Tool You Need

AI Coach

Powered by Anthropic's Claude, a real deep-reasoning model, not a scripted chatbot. It reads your food log, biomarkers, and goals before every answer, remembers what matters to you, and can log food, weight, and biomarkers straight to your diary from the conversation, with your confirmation. How the AI keto coach works

Free + Premium

Macro Tracking

2.3 million+ foods and products across FatSecret, USDA FoodData Central, and Open Food Facts, plus an NIH-sourced supplement database and curated restaurant menus. Net carb tracking, GI scoring, and barcode scanning in one place.

Free + Premium

Glycemic Index Scoring

Every food color-scored with a GI scale so you always know exactly what keeps you in ketosis and what spikes blood sugar. Built into the food database, no manual lookup.

All tiers

Agentic Metabolic Forecast

A 3-day energy and weight projection built from up to 14 days of your own logged history, not population averages. It won't run until you've logged at least 3 days, and gets sharper with every day you add. Most users see a meaningfully more informed picture by day 100.

Available on Premium

AI Body-Fat Reading

Take a photo in the app and get an AI body-composition read, including body-fat percentage, so you can track composition rather than scale weight alone. Your photo is analyzed and never stored on our servers. We keep the numbers only, never the image.

Available on Premium

Ketone & Glucose Log

Log your blood BHB, urine ketone readings, and blood glucose. Track trends over time with full chart history. GKI (Glucose Ketone Index) calculated automatically.

All tiers

Electrolyte Tracking

Sodium, potassium, magnesium, and calcium tracked daily against science-backed keto targets. Critical for preventing keto flu and optimizing performance.

All tiers

Fridge-to-Recipe

Tell the AI what's in your fridge and get custom keto recipes generated instantly. Full macro breakdown included. Premium-exclusive, in the app now.

Premium only

3,800+ Recipe Search

Recipe search now reaches FatSecret's recipe database: 3,800+ recipes with ingredients and step-by-step directions. Searchable alongside 289 KetoNoir cultural recipes across Latin, American, Italian, French, and Mediterranean traditions, 182 of them keto-adapted.

The AI Coach

Not a Chatbot.
A Real Coach.

The KetoNoir AI coach is Anthropic's Claude, a real deep-reasoning model, not a scripted chatbot. It reads your actual food log, macro targets, biomarkers, and health goals before every response, and remembers your history. It knows what you ate today, how close you are to your carb limit, and how your patterns are trending over time. What makes it agentic rather than conversational is that it doesn't just answer: it acts, writing straight to your diary and to the app itself once you confirm.

Read the full coach breakdown →

What It Actually Does
Writes food, weight, glucose, ketones, blood pressure, even a full cholesterol panel directly to your diary from a normal conversation, with a confirmation step before anything saves
Reads today's log, the prior 7 days, and how that compares to the 7 days before, on every turn, so it responds to your trend, not just your last message
Remembers what matters to you in named categories you can view and delete any time: allergies, goals, medical conditions, dislikes, preferences
Acts on the app itself from chat: builds a meal plan into My Meal Plans, generates a recipe, adjusts your macro goals
Built-In Guardrails
Never diagnoses conditions or recommends medications
Detects disordered eating language and redirects with care
Refuses to set calorie goals below safe minimums
Knows BHB reference ranges, adaptation timelines, and electrolyte targets cold
Routes insulin and medication questions to your healthcare provider
AI Coach · Live Preview
What's a good keto lunch I can make fast?
KetoNoir Coach Something easy that hits your fat and protein targets without touching your carb limit. 3 scrambled eggs in 1 tbsp butter, 2 oz cheddar, and half an avocado. Takes 5 minutes, no measuring required. You've got 8g net carbs left for the day so this works perfectly.

Recommended tool

A GKI is only as good as the meter behind it.

KetoNoir calculates your Glucose-Ketone Index automatically. That number only means something when the readings behind it are real: blood glucose and blood ketones, not a urine strip that fades by the afternoon.

Why we recommend Keto-Mojo

Blood readings your log can trust.

Urine strips measure spillover, not what is in your blood, and they lose accuracy within days of opening. A real GKI needs blood glucose and blood ketones. Keto-Mojo is the meter we point people to for exactly that.

Blood glucose and blood ketones in one kit, the two numbers a GKI actually needs.
Log every reading in KetoNoir next to your macros, ketones, and adherence.
We handle the plan and the coaching. The meter handles the proof.
