Grammarly Review: The writing safety net that works everywhere

Grammarly is the AI tool we think about least and benefit from most. It sits in the background of everything — browser, email, documents, even Slack — and quietly prevents the small writing failures that cost credibility.

The core corrections are flawless and have been for years: spelling, grammar, punctuation, at near-perfect precision. What justifies Premium is everything above that line. The clarity suggestions catch the passive constructions and buried premises that make writing feel bureaucratic. The tone detector is genuinely useful before difficult emails — it has flagged messages that read harsher than intended, and that is worth the subscription by itself.

Where Grammarly disappoints is creative writing. Its suggestions push toward clean, safe, professional prose, which is exactly wrong for a novel or a brand that sounds distinctive. Several of our test writers turned it off entirely for fiction. It is a business-writing tool; do not buy it as anything else.

The free tier is generous — the core corrections cost nothing, and for many students that is enough. Premium, at around $12 a month on annual billing, buys the tone, clarity, and rewrite features. The generative AI features are competent but redundant if you already pay for ChatGPT or Claude; we would not pay for Grammarly on their strength alone.
