# AI Date (AI 데이트)

> AI Date is a chat-based Korean date-course planning app built on Anthropic's Claude API, developed by the AI division of Purify Solution Co., Ltd. (주식회사 퓨리파이솔루션), a Korean corporation incorporated on 2026-03-13. Status: in development, not yet launched. There are no users, customers, partners or funding yet, and place-data integrations are planned, not live. Not affiliated with Anthropic.

## Product
- Users describe area, date and time, budget, preferences and mood in a chat (Korean or English).
- Claude builds an ordered date course (e.g. activity, cafe, restaurant, walk) that fits the time window and budget.
- Each stop can be swapped for alternatives; the course is re-checked after a swap.
- Each candidate shows details such as menu, price, opening hours and reviews, planned to come from licensed third-party place-data APIs with attribution.
- The product mockup on the website uses fictional sample data.

## How Claude is used (design)
- Claude Messages API with a versioned system prompt.
- Tool use: search_places, get_place_details, get_alternatives, estimate_travel_time (read-only, executed on our server).
- Schema-validated JSON course output; place IDs must come from tool results, so Claude cannot invent venues.
- Prompt caching for the system prompt and tool definitions across swaps.
- Model routing: a smaller Claude model for parsing and quick swaps, a larger Claude model for full course planning.
- Offline course-quality evals: schema validity, budget fit, opening hours, travel distance, preference match, grounding, cost and latency.
- Development: the team uses Claude Code.
