RI-SWAP is a human-controlled community exchange application where AI helps people clarify reciprocal offers while each participant retains every decision. Community members and small businesses often have complementary needs, but informal exchanges become difficult when scope, quantities or consent are unclear. RI-SWAP structures an Offer, private Proposal, review of the same version, acceptance by both parties and Agreement. A website-for-catering scenario makes those choices concrete. Hoa Mai is the app assistant. Its server-side Muse Spark 1.3 adapter requests structured Offer details and clarification, validates output and presents suggestions for human review. AI does not publish, accept or decide terms for either party. Agreement Reached records consent to a version; it does not establish payment, delivery, service quality or fulfilment.
