Frequently asked questions
Can a grammar checker replace an editor?
No. It catches mechanical problems and patterns. A human editor catches story, logic and voice problems a tool cannot see.
Which is best for a novel?
ProWritingAid or AutoCrit. Both report on pacing and style in fiction. Grammarly is better for short everyday writing.
