Greasy Fork is available in English.
This greasy script analyzes the interests of any person's dating profile and the current time and automatically generates a message based on them. The message doesn't look computer-generated. It's better than sending a copy-and-paste message to users, as they'll be suspicious if there's nothing in the message pertaining to them personally. I've gotten many dates and two girlfriends using this sneaky script. You get the option to edit and decide whether you want to send the message.
