Everything you need to know about Diet Mate, the voice-first nutrition app that builds your nutritional memory. Find answers about how it works, pricing, privacy, and more.
Diet Mate is a voice-first nutrition tracking app that captures the context of your meals — not just what you ate, but when, where, why, and how it fits your life. It uses AI to build your nutritional memory over time, revealing patterns that help you understand your eating habits and make better decisions. The more you use it, the more it understands you.
Nutritional memory is your personal food history enriched with context — your routines, constraints, timing, environment, and how you felt. Unlike calorie counting alone, nutritional memory helps you see why you eat the way you do, making it easier to identify what truly works for your lifestyle. It is the core concept behind Diet Mate.
Diet Mate does not rely on external food databases or barcode scanning. Instead, you describe meals in your own words via voice, and AI estimates nutrition from your natural description. This captures the context that matters — your routine, constraints, and environment — building a nutritional memory that reveals patterns, not just calories.
No. Diet Mate works best when you log consistently, but there is no pressure to track everything. The app learns from what you do track, building your nutritional memory gradually. Even partial tracking reveals meaningful patterns over time.
Open Diet Mate, tap record, and describe your meal however you naturally would. For example: "Had eggs and toast with coffee at my desk before the morning meeting." The app captures your exact words and context. No database searching or portion estimation required — your voice provides richer information than any barcode scan.
Diet Mate's AI analyzes your natural description — ingredients, quantities, cooking methods, and context — to estimate nutrition using advanced language models. It understands your meal the way a nutritionist would from hearing you describe it, handling compound dishes, homemade recipes, and cultural food contexts that traditional databases cannot cover.
Every Monday, Diet Mate analyzes your logged meals from the past week to create a personalized report. It includes a summary of your eating patterns, detected trends, and one priority action to improve your nutritional memory. It is data-driven insight tailored to your life, not generic advice.
Memory Score is Diet Mate's proprietary metric that rewards the quality and depth of your tracking. It increases when you log consistently, include context like time and environment, and engage with your weekly report. It rewards qualitative engagement — not just volume — without encouraging restriction or guilt.
