Grammarly Review and verdict 2026

Your personal English writing assistant.

From 12€/mo.

Our take

Understanding Grammarly.

Grammarly is the best-known English writing assistant. Plugged in as an extension in your browser, email or word processor, it corrects in real time well beyond spelling: grammar, phrasing, tone, clarity. For someone who writes in English without being a native, it's a safety net that prevents the kind of mistakes that stand out in a client email or a sales proposal.

The free version covers basic corrections. The Premium plan, around $12/month annually ($30 monthly), unlocks style, tone and rewrite suggestions, plus AI features. Team plans also exist.

Who it's for: people writing professional English daily. Two limits to know: it's mainly relevant in English (French is weak), and a general AI assistant like ChatGPT or Claude now does a large part of the proofreading and rewriting, for free or cheaper. Grammarly keeps the edge of real-time correction built in everywhere, with no copy-paste.

Practical uses

Proofread English emails and documents.
Adjust the tone of a professional message.

Pros and cons

What Grammarly does especially well — and the limits to anticipate.

Pros

Real-time corrections in most apps.
Useful tone and clarity suggestions.
Free version is already usable.
Generative-AI features on paid plans.

Cons

English-focused, limited other languages.
Advanced features locked behind the paid plan.
Extension accesses typed content.

Grammarly: when it makes sense.

Grammarly fits heavy professional English writing; for another language or occasional needs, a native checker is enough.

Keep if

You write a lot in English every day.. You want real-time corrections and tone smoothing.

Grammarly becomes worthwhile when

You use it at least once a week
The monthly cost (€12) is small next to the time it saves you

Challenge if

You mostly write in a language Grammarly doesn't cover.. Your word processor's built-in checker is enough.

Grammarly becomes too expensive when

You use it less than once a month
A cheaper alternative already covers the essentials: Corrige et réécrit, nettement meilleur en français.

Our verdict on Grammarly.

Why this verdict

Very good

Grammarly is fairly easy to replace with an alternative, a free tier to test before paying, clearly documented use cases.
