Buyer AI vs Seller AI

Haggling on a marketplace has real hurdles: writing the message is a chore, you cannot tell how far a seller will bend, and you just want an answer quickly. This mock app hands the whole exchange to an AI agent on each side.

You set your target price and your agent's personality, then send it off; it trades offers with the seller's agent on the spot and drops a notification once they agree. The point is that you stop worrying about tone — and can negotiate with several sellers at the same time.

In the spirit of an AI agent hackathon, we leaned on AI for the making as well: bouncing ideas off a Figma-MCP-connected board, laying out three very different mockups in Claude Design to compare, and then writing the app with Claude Code.
