Fast answer
Grammarly is a strong default for broad writing improvement, but alternatives may be better for long-form editing, SEO content, team style guides, or budget constraints.
Decision criteria
- Does it work where writing happens: browser, docs, email, CMS?
- Does it catch clarity issues, not just typos?
- Does it preserve the writer's voice?
- Is the paid plan justified by weekly usage?
Best workflow
Draft quickly, edit for structure, run grammar/clarity checks, then do a final human read for facts and tone.
