"This encourages you to write only using frequently used words"<p>"This helps you to write only using top words"<p>These two sentences could have different meanings though. What is a top word? The best ones? The frequently used ones? Without context it might not be clear.<p>Encourages and helps can also be very different.<p>---<p>Anyway it is quite cool I guess. Maybe you could add automatic synonyms for words that are within the 1000.
