Grammarly (Pro) review 2026

The editor rather than the writer: it works inside every app you already type in and makes your own writing clearer

Is the Grammarly Worth It?

Best for editing your own writing. Grammarly is the tool to buy if the problem is your own drafts rather than a blank page. As a generator it is the weakest here, and it does not pretend otherwise.

Grammarly Pros & Cons

Pros
  • Works in Gmail, Docs, Word, Slack and the browser — no copying between tools
  • Caught every real grammar issue our editors flagged in the rewrite brief
  • $12 a month, and the free tier is genuinely useful
  • Business plan enforces a shared style guide across a team
Cons
  • As a generative writer it scored 5 — it is an editor first
  • Suggestions can flatten a distinctive voice if accepted wholesale
  • Full generative features need the paid tier

Why it scored 8.4

Grammarly is the tool to buy if the problem is your own drafts rather than a blank page. As a generator it is the weakest here, and it does not pretend otherwise.

Where it loses

Generation quality.

Still the right pick for

People who write plenty and want it tightened.

What owners say

No reader ratings yet. This block fills in from real submissions only — we never write, buy or generate reader reviews, and none of them touch the editor score.
