THE IDEA, AND THE BOUNDARIES
One journey.
A thoughtful start.
Two Cities Korea is a pre-launch travel-planning concept for US and UK visitors interested in combining Seoul and Busan. Two Cities Korea is the Seoul–Busan travel-planning service concept of 터치하트관광. This demo is not a tour operator or booking service.
The itinerary demo uses fixed, deterministic rules in your browser. Trip length controls the city split, pace controls optional stops, and interests rotate through a small set of travel ideas. It does not use AI, call Claude, check live availability or generate a personalised expert recommendation.
Business details
Business opening date: 2 January 2026. Representative: Eric Choi, CEO. Legal trade name: 터치하트관광. Two Cities Korea is our travel-planning brand.
The United States and United Kingdom are intended audience markets, not a claim of legal operations in either country. The current product is a pre-launch planning prototype, not a live booking platform.
Why these two cities?
The concept pairs Seoul’s palace, neighbourhood and riverside ideas with Busan’s hillside, market and coastal ideas. The connecting rail day is deliberately left spacious. A draft should help you ask better questions, not disguise uncertainty.
Claude integration: a future plan
No Claude integration is currently implemented. A future version would explore:
- Source-grounded explanations: explain itinerary choices using retrieved official material, with traceable source links and retrieval dates.
- UK and US localisation: adapt English spelling and wording without altering factual meaning.
- Numeric and source fidelity: preserve fares, dates, durations, units and caveats exactly when supported by a source; never invent missing numbers.
- Abstention: say when information is missing, conflicting or out of date instead of supplying a plausible guess.
- Human review: review source quality and travel guidance before public release, with a process to correct errors.
Any future AI feature would require a separate implementation, privacy review and clear notice before information is sent to a provider. This static demo has no API keys, backend or Claude runtime calls.
A test plan, not a track record
There are no measured success claims. Proposed future tests would assess citation coverage and source correctness, exact numeric fidelity, appropriate abstention on missing information, US/UK wording consistency, accessibility, and whether test participants can understand and revise an itinerary. Test criteria and review methods would be defined before evaluation; no user results or performance scores are claimed here.
