Xchange converts currencies instantly, no sign-up, no login, no accounts. Enter an amount, pick two currencies, get a live rate, quick-select pairs, both-direction rates, and a copy button. Each conversion includes a short insight note on the pair (major vs minor, rate size, amount sensitivity). It is a local rule-based heuristic, not a live model call, since a static site has nowhere safe to hold a real API key.

Repo creation date comes from GitHub and can't be altered by the author. Commit dates can be rewritten, so treat them as context rather than proof. Build window: 2026-08-28 18:00 UTC → 2026-08-30 18:00 UTC.

Declared by @chukaufo
Model use is declared, not detected. Hackyard cannot verify which model wrote code and does not claim to. A receipt shows a session existed, it does not prove that model wrote what shipped, and most builders won't attach one. Treat it as context, the same as commit dates.
