NegotiateAI — Demo video

NegotiateAI is an AI-powered negotiation agent that helps buyers negotiate better deals while maintaining control over their budgets and final decisions. Negotiating prices can be time-consuming, stressful, and difficult, especially when buyers are unsure how much to offer, when to compromise, or how to respond to counteroffers. NegotiateAI addresses this challenge by combining AI-driven negotiation strategies with clear budget constraints and human oversight. Users define their product, opening offer, target price, maximum budget, and negotiation preferences. Powered by Meta's Muse Spark Open model, the agent analyzes negotiation history, generates context-aware counteroffers, and adapts its responses as negotiations progress. The application supports two modes: Manual Mode: Users review and approve negotiation responses. Autonomous Mode: The agent negotiates within predefined limits, while final agreements remain subject to human approval. Built with Python, FastAPI, and a React frontend, NegotiateAI demonstrates how agentic AI can support real-world decision-making through structured workflows, contextual reasoning, and human-in-the-loop safeguards. The goal is to make negotiation more accessible, efficient, and transparent while ensuring that AI assists users rather than replacing their decision-making authority.
