Introduction
Welcome to the Nutrition AI Platform!
Nutrition AI by Passio gives developers a single integration point for AI-powered food tracking and nutrition intelligence. Send a photo, a voice note, a barcode scan, or a text query — and get back structured nutritional data from a 2.5M+ food database, ready to use in your app.
The platform combines cloud-based AI models (LLM-powered food recognition and natural language understanding) with a comprehensive nutrition database covering branded products, generic foods, and recipes. You send input, Passio identifies the food, matches it to the database, and returns structured nutrition data — calories, macros, micros, portions, and serving sizes.
Who is this for?
Developers building health, fitness, nutrition, or wellness apps who need food logging, meal tracking, or dietary analysis.
Teams adding food recognition or nutrition features to an existing mobile or web application.
Companies building AI-powered nutrition coaching, personalized meal planning, or food shopping experiences.
What can you do with it?
Image Recognition — take a photo of any meal and get identified ingredients with nutritional data.
Food Database — search and retrieve detailed nutritional information from a 2.5M+ food database.
Voice Logging — speak or type what you ate and get structured food entries with portions.
