kerak
AI-powered personal nutrition assistant. Calorie tracking, recipe generation, weekly meal planning and nutrition advice - all driven by Mistral AI.
Demo
The Problem
Tracking nutrition manually is tedious - counting calories, balancing macros, finding recipes that fit your goals. Existing apps are either too complex, filled with ads, or lack intelligent suggestions. There's no simple tool that understands what you eat in plain language and builds a personalized plan around it.
The Approach
Kerak lets you log meals in natural language - just say what you ate and the AI figures out the rest. It generates recipes from your ingredients, builds weekly meal plans based on your goals, and gives personalized nutrition advice. The whole experience is conversational and effortless.
Technical Choices
Mistral AI for everything
