an overly picky language style checker

Nitpicker is a language style checker which compares your text with a large database of style warnings, common errors, or warnings indicating that you may have once more used the wrong word or preposition. Nitpicker’s goal is to implement the old proverb “shame on you if you fool me once, shame on me if you fool me twice”: the moment your supervisor, colleague, reviewer, or local native-speaker finds a mistake in your text, any repetition is just embarrassing.
