TRUSTBANK and Recursive launched Choice AI, an AI agent that simplifies Japan’s Furusato Nozei tax donation program. Donors often struggle with thousands of regional gift options. Choice AI uses OpenAI GPT-4.1 models to offer personalized, conversational recommendations within the Furusato Choice app.

The system relies on a multi-agent architecture that routes user intent to specialized agents like Search, Recommendation, and Greeting. It tailors interactions based on whether users are first-time donors or returning. Dynamic prompting and randomized search results help surface diverse, lesser-known gifts from smaller municipalities.

Early results show higher conversion rates than standard search. TRUSTBANK plans to expand AI into a full AI concierge for the platform. Choice AI improves donor engagement while promoting regional equity—a smart application of LLM personalization in civic tech.

Beyond gift discovery, this project highlights how conversational AI and retrieval-augmented generation (RAG) can reshape user experiences in complex decision-making environments like public programs.
