Grammarly: review, test, pricing and alternatives (2026)

Grammarly is a veteran: long before the generative-AI wave, it was already the checker millions of English speakers left running in the background of their browser. It navigated the AI turn by going from a simple 'grammar checker' to a genuine writing assistant, without losing what made it strong — being everywhere you type: email, Google Docs, social media, chat.

In practice it corrects in real time, but reaches well beyond spelling: clarity, tone, concision, and now a generative AI that rewrites or drafts on demand, right inside the text field. That omnipresence is its real edge: no tool to open, the suggestion lands the moment you're writing.

Two important caveats. First, it's in English that it's unbeatable — for a non-native writing professionally in English it's near-essential; French, by contrast, is covered far more superficially and won't replace a human proofread. Second, its suggestions can be a touch too prescriptive, sometimes smoothing away a distinctive voice. The free tier handles the basics; advanced style and AI tip quickly into Premium.

For writing English without flinching, we know nothing better. In French, it helps without replacing a human proofread.
