Write a prompt. See which skill does it better.

Enter a prompt. Parley picks two skills to compare, or you choose them. Your model answers with each, blind, side by side. You pick the better one, and the model picks too — we record both. The result joins the public record. We use your API key for this run only, and never store it.
