Common questions about Grammarly
What is Grammarly?
A writing assistant that checks grammar, spelling, punctuation, clarity and tone, working in a browser, an editor or a desktop app across most places people write.
Who is it for?
Anyone producing written work who wants a second pass for mechanics — students, professionals, and people writing in a second language in particular.
Is Grammarly free?
It is freemium, scored 4.6 here. The free tier covers grammar and spelling; paid plans add tone, clarity and rewriting suggestions.
Is its advice always right?
No. Style suggestions are opinions, and a grammatically correct sentence can be flagged because a rule prefers it differently. Accept a change when you agree with the reason, not because it appeared.
Use cases
Catching mechanical errors
Typos and agreement mistakes are what a checker does reliably, and they are the errors readers notice most.
Working in a second language
Explanations of why something is wrong are more useful than a corrected version you have to reverse-engineer.
Checking tone before sending
A tone warning is a prompt to reread an email, which is worth having before it goes to a client.
Pricing
Grammarly carries an assessment of 4.6 in our directory. The free tier covers grammar and spelling; paid plans add tone, clarity and rewriting. The question worth asking is whether the extra suggestions improve your writing or flatten it. Details are on the vendor site. The Grammarly site publishes the live figures.
Alternatives
- LanguageTool — Open source, self-hostable, and narrower in scope.
- ProWritingAid — Longer-form reports, favoured by fiction writers.
- Reading it aloud — Free, and it catches more than people expect.

What to check first
Decide what may leave your machine
A cloud checker reads the text it checks. Establish the terms before pasting anything confidential.
Do not accept changes blindly
The suggestions are consistent, not correct. A flattened voice is a real cost of over-accepting.
