Simplifying Japan's Hometown Tax Donation Program with AI
Japan's Furusato Nozei (hometown tax donation) program allows taxpayers to support municipalities through tax deductions. However, with roughly 760,000 thank-you gifts available, the experience can feel overwhelming. TRUSTBANK's Furusato Choice platform recognized this and turned to AI to help users navigate options.
Building Choice AI Through Strategic Partnership
TRUSTBANK partnered with Recursive, an official OpenAI services partner. The teams developed Choice AI, powered by the OpenAI API, helping users discover gifts through interactive conversations.
Multi-Agent Architecture
Choice AI uses a sophisticated multi-agent architecture where a routing model analyzes user intent and delegates tasks to specialized agents. The system runs on GPT-4.1 series models with dynamic switching based on latency and accuracy.
Results and Impact
Users employing Choice AI achieved higher conversion rates than those using standard search. By drawing out preferences users struggled to articulate, the AI recommends specific gifts matching both stated and implicit needs.
TL;DR
- TRUSTBANK integrated OpenAI API to build Choice AI for personalized gift recommendations across 760,000 options- Multi-agent architecture with dynamic routing personalizes experience and improves conversion rates
- Controlled randomness promotes fairness and discovery of lesser-known regional products
