Pantree - Your pantry insider, is an AI kitchen assistant that tracks inventory, remembers user preferences and time-bound dietary constraints, and takes real action: automatically adding used and expiring items to a grocery list and logging unused, expired items to a throwaway log. Rather than static rules, every suggestion is produced by an adaptive scoring function that weighs expiry urgency, preference match, and past waste/usage patterns computed live from MongoDB Atlas, and every response includes a plain-language explanation of exactly which signals drove it - transparency by design, not a bolted-on dashboard. Built to directly address a persistent, expensive problem (U.S. households are responsible for 40-50% of the country's food waste), it demonstrates genuine agent memory and action-taking rather than a chatbot wrapped around a database, with cross-session context and broader vector-search-driven ranking scoped as clear next steps beyond today's build.
