I tried Grammarly back in its very early days (before customers started getting hit with sneaky auto service charges) and was completely and utterly underwhelmed. Grammarly is useful perhaps to non-English speakers or to many of the unfortunate youngsters of the current generation who slept through English Composition classes and take the majority of their grammar rules from colloquial text speech and emoticon use. For the portion of the population either well-educated or well-experienced with proper written English and basic composition, Grammarly is entirely obsolete. Not only are its grammar suggestions limited to the most obvious grammar flaws, but I was astounded by how many grammar errors it detected that were not errors at all and would have resulted in a grammarly "fix" that would have actually made the structure of the written works even worse (for example, the proper use of semicolons seems to be outside of Grammarly's abilities and it frequently detects sentence fragments that are not actually there.) In short, do not use this tool unless you want a program that serves as no more than a screaming sign of your own English incompetence; proper English users will get by with Word or just fine without this useless program.
