Using multimodal AI for allergen detection

AllergySnap blends OCR for text extraction, an ontology of allergens and synonyms, and LLM reasoning that explains why an item is risky. The output is an explicit safety signal with highlighted ingredients, not a black‑box score.

• OCR → ingredients and advisory text
• Normalization → map synonyms (e.g., casein → milk)
• Reasoning → LLM checks against the user profile and cites matches
