iMessage Food Photo Nutrition Analyzer with GPT-4 Vision & Memory

This n8n workflow enables seamless nutritional analysis of user-submitted food photos received through iMessage. Triggered by a Blooio webhook, it validates and extracts images, processes them with OpenAI's GPT-4 Vision for accurate calorie and nutrient breakdowns, and stores results in a Postgres database for memory and historical tracking. A friendly, detailed report is then sent back directly in the chat.

Key benefits include hands-free meal logging, automated diet summaries for daily/weekly/monthly insights, and integration into messaging for effortless user experience. It saves time on manual food tracking, provides AI-powered estimates for better dietary awareness, and scales for apps in fitness, healthcare, or wellness.

Ideal use cases: Personal calorie trackers, virtual nutrition coaching via chat, food journaling in wellness apps, or sales tools for diet product demos. Note: Results are estimates; pair with professional advice. Requires Blooio API, OpenAI key, and Postgres setup.
