Grammarly
A writing assistant that checks grammar, clarity, and tone as you type, with AI features for rewriting and adjusting tone, built as a browser extension and app rather than a chat interface.
Best for
Catching grammar and clarity issues in emails, documents, and messages as you write them.
Suitable for
Anyone who writes in a browser or desktop app and wants real-time corrections, not a chatbot.
Features
- Real-time grammar and clarity checks
- Tone suggestions
- AI rewriting
- Browser extension
What you get for free
The free tier covers spelling, grammar, and basic punctuation across the browser and desktop apps. Paid plans add tone adjustment, clarity rewrites, and full-sentence suggestions.
Where Grammarly falls short
The parts a product page will not tell you.
- Suggestions tend toward a neutral corporate register, which can quietly sand down a distinctive voice.
- It misses errors that depend on meaning rather than grammar — the wrong name, the wrong number, the right word used wrongly.
- Upgrade prompts are frequent and appear inside the writing experience.
- The browser extension can conflict with rich text editors and occasionally interferes with typing.
Who should skip it
Creative writing where voice matters more than correctness, and anyone hoping for a one-click rewrite of weak thinking.
Getting started
- 1Install the browser extension or desktop app and it starts working in the boxes where you already write.
- 2Set the goals — audience, formality, intent — before trusting tone suggestions. Defaults assume generic business writing.
- 3Accept corrections freely, but read rewrites twice. Correct and lifeless is not an improvement on rough and human.
Our take
Reliable at the mechanical layer of writing, which is a real and underrated benefit if English is not your first language or you write a lot under time pressure. Treat it as a proofreader rather than an editor: it catches what is wrong, it does not know what you were trying to say.
