The world's most accurate food tracking - powered by AI.
Penng uses a chain of AI models that work together to identify meals from photos, barcodes, or text in seconds. Each model queries multiple food databases and cross-checks entries using your location data to match regional ingredients and brands. From local staples to international meals, Penng ensures your nutrition data is precise, contextual, and truly personal. Food tracking has never been faster - or more accurate.
