Wordfully's answer
Wordfully grew out of a simple writing problem: stopping to check every sentence can interrupt the task at hand. The team built it to bring corrections and clearer alternatives into the places people already write. The aim is to help people express their ideas while leaving the final choice of wording with the writer.
