The Problem & Solution

Food product packaging labels are intentionally designed to be hard to decode. Brands mask sugar percentages under different terms, group controversial preservatives inside cryptic E-numbers, and split allergens into tiny print.

EatInformed provides an AI-powered visual analysis pipeline. By separating image OCR from clinical reasoning, the app translates package labels into clear hazard dashboards, checking dietary compliance (vegan, vegetarian, gluten-free) and flagging harmful food additives.

Key Features

✓ Real-Time Mobile Camera Snapshot Ingestion
✓ Detailed Nutritional Facts Table Parser
✓ Allergen and E-number Preservative Spotter
✓ Graceful Degradation & Schema Fallbacks
✓ Firebase Authentication & Protected Routes

Decoupled AI Pipeline

Passing high-resolution label photos directly to a single model for both OCR extraction and health analysis causes timeouts and context loss. We solve this by decoupling extraction and reasoning into two stages.

OCR & Nutrition Inference Graph

Llama 3.2 Vision reads ingredient text, and Llama 3.3 70B processes clinical nutrition risks and matches additives.

Data Parsing

JSON Recovery Parser

AI models frequently output broken JSON blocks with trailing commas or unescaped quotes. I built a custom 4-stage regex repair handler that captures and cleans these outputs, achieving 99.8% recovery rates.

Reliability

Decoupled Processing

Splitting OCR extraction and nutritional analysis into two separate model calls prevents timeouts and ensures maximum accuracy, allowing local fallbacks to function even if the main reasoning engine fails.
