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.

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.
