Worst forWriters wanting substantive editing. Grammarly fixes mechanics and tone; it does not improve an argument.Anyone needing original writing. QuillBot reworks text you already have and is not a drafting tool.
Skip it ifYou write mainly in one app that already has good built-in checking. The value here is breadth of coverage.You want an AI assistant. This is a focused rewriting and summarising utility, not a general-purpose one.

Why Grammarly is flagged here

Works everywhere you already write, which is the entire reason to pay for it. It has the lowest ongoing cost of the tools compared here. We compare on the price you keep paying, not the introductory rate — a plan advertised cheaply that renews higher is ranked on its renewal price. Read the methodology.
