Fortunately, with a few open source utilities, I can avoid this distraction. I process words pretty often for writing technical and creative pieces, and ducking out of my text editor to open a web browser, much less to visit a site that requires me to log in, is usually too much a bother for me. It's a useful tool, but you're required to register and log in to use it, and I rarely keep website login data in my cache. Grammarly is popular among many teachers, students, business people, and others who need to write or process a lot of words on a regular basis.
