One of the best ways to decrease the number of wasted clothes and contribute to the development of communities is to donate them. However, because of the lack of controlled channels, unused clothes do not always go to the target audience and instead become waste instead of fulfilling them. The purpose of this project is to develop Rewearify an AI Based Sustainable Clothing Donation Platform that will help bridge the donors and NGOs in a transparent and seamless manner! It is based on the established MERN stack (MongoDB, Express.js, React.js, Node.js) to manage user roles, the item submission and approval process. Increment in the level of automation, Python FastAPI AI Service has been created, which employs Finite State Machines (FSM) to track statuses, Content-Based Filtering to combine words co-occurring and semantic matching using similarity of terms, Decision Trees to detect Fraud, K-Means Clustering due to logistic reasons. The site supports Socket notification in realtime.IO and status tracking and analytics dashboards, which are useful in facilitating the donation process. Rewearify also shifts to a more demand-based model of supply and introduces transparency and intelligent automation to the humanitarian supply chain.
