About this site

Travel-pass advice online is mostly vibes: "totally worth it!" next to an affiliate link. We built the boring alternative — a calculator that enumerates every option for your actual itinerary and shows the arithmetic.

What we promise

• Deterministic results: the same itinerary always produces the same answer.
• Verified, versioned prices with visible confidence levels — and honest "we don't know" answers when data can't be verified.
• Commissions can never influence a recommendation; the separation is enforced by automated tests (see methodology).
• No accounts, no personal data collection beyond anonymous usage statistics (see privacy).

What this site is not

Not a booking agency, not a tour operator, and not affiliated with KORAIL, the Seoul Metropolitan Government or any pass vendor. Product names are used to identify the products being compared.

Questions or corrections? We genuinely want to hear about any price that looks wrong — every value links back to a registered source.
