MacKeylogger

Small, simple and functional, MacKeylogger monitors and records keystrokes on your Mac. Best of all, MacKeylogger runs in the background - invisible to most users.

Keystroke logging works in any language your computer supports and captures text typed in any application or web page except passwords. That makes MacKeylogger a great monitoring tool for parents who want to keep tabs on the messages their kids send.
