How we rank Grammarly alternatives

Every tool above is scored against the same six inputs: monthly cost, time-to-first-result, output quality in our hands-on tests, free-tier generosity, category fit, and reader signals. The ranking is editorial and computed before we know whether an affiliate program exists. See our about page and affiliate disclosure for the full method.
