Explain Like I'm New
A digital mail-sorter. It reads an incoming document and throws it into the correct bucket. (e.g., Is this email Spam or Not Spam? Is this news article about Sports, Politics, or Technology?)
Real World Example
Gmail's automatic inbox tabs. Gmail reads every incoming email and classifies it into 'Primary', 'Social', or 'Promotions' so your inbox stays clean.
