Ecoceipt is a Kotlin-based Android app that empowers MSMEs to digitize paper receipts using OCR, extract structured sales data with LLM, and receive AI-powered stock recommendations — all aimed at minimizing overstocking and reducing food waste for a more sustainable future. 🌱

Overstocking contributes to unnecessary food waste, which releases harmful greenhouse gases and strains local economies. Ecoceipt empowers small businesses to only stock what’s needed — using AI and data-driven decisions for a greener planet. 🌏
