We've all done it. Your fingers are a-flying and next thing you know, you've written 'sneak peak' when you meant to write, 'sneak peek.' Now, if you make that mistake on Twitter, @StealthMountain will correct you. The account is a bot that searches for this single incorrect phrase and sends users a message that says, "I think you mean 'sneak peek.'" That's it. It does nothing else. Well, technically, someone also favorites the enraged responses of the people who have been so corrected.
Since the account went live in late November, it's alerted more than 8,000 people that he or she had a homophonic mixup.
