nudl strips tracking parameters off URLs you copy — in Slack, Discord, a terminal, a doc, your browser, anywhere — and hands back the same real link, trimmed. It is not a URL shortener: no alias, no server, no redirect. It makes zero network calls, keeps a local audit log of every change, and can undo any edit within three seconds. `nudlw` is the tray app (hotkey or automatic mode); `nudl` is the command line, for pipes such as `Get-Clipboard | nudl | Set-Clipboard`.
