- Eric John Hollowell
- I strongly discourage the use of QuillBot. I appreciate some proofreading tools because of my propensity for typographical errors; however, more than ninety percent of the corrections recommended by QuillBot would have converted my correct writing into solecisms. Here was the outright offensive malignment (and grammatically false, whenever referring to the singular God by name) that prompted me to switch to LangaugeTool: QuillBot falsely identified the capitalization of “God” and “Godly” as unconditionally erroneous. (For the sake of validity, I know all of the grammatic rules of Oxford and the MLA. I acknowledge the contestability of many rules, but even if an atheist is trying to belittle God through insidious resources like this, there is no ambiguity regarding this particular capitalization of the first person’s name of reference of a person or being.)

- gilmer gonzalez

- William H
- Does what I need for the most part, but I am absolutely annoyed with how often it suggests semicolons. We live in the modern day, we don't all know how to use semicolons and this app recommends them like every other sentence. There needs to be an option to remove semicolons as a correction.
