What the Free Version Actually Does
Grammarly Free isn't useless. It catches the basics well — spelling mistakes, basic grammar errors, punctuation issues, and some sentence structure problems. For everyday emails, forum posts, and casual writing it's perfectly fine.
Where it starts to fall short for students is in academic writing. It won't tell you that your argument is unclear, that your essay intro is too passive, or that your sentence structure is monotonous. That's where Premium comes in.

The Plagiarism Checker Alone Might Justify It
Academic plagiarism checkers like Turnitin can flag passages you didn't even realise were too close to a source. Grammarly Premium's plagiarism checker lets you run your essay before submitting — so you can rephrase anything flagged before it goes through your university's system.
If you only need the plagiarism checker for a dissertation period, sign up for one month, use it intensively, then cancel. Monthly plans are flexible and there's no contract.
Is It Worth It Day-to-Day?
If you write a lot — essays, reports, emails to lecturers, application forms — yes. The clarity suggestions genuinely improve writing quality over time because you start to understand why your sentences are being flagged. It's not just correcting you; it's teaching you patterns.
What Grammarly Won't Do
Be honest about the limits. Grammarly won't fix a badly structured argument. It won't tell you your research is thin. It won't replace careful reading and editing. It also sometimes over-suggests changes that make academic writing sound too casual — you need to use your own judgement on what to accept.

Try Grammarly Free →Grammarly vs Microsoft Word's Editor
Word has improved its Editor feature significantly, and it's free with your student Microsoft 365 account. For basic checking it's solid. But Grammarly's suggestions are more nuanced, the tone detection is better, and the plagiarism checker is a completely different product.
⭐ Sento Verdict: Grammarly Free is worth installing for every student — no debate. Premium is worth it if you write regularly for your course, especially if you're in your second year or beyond. The plagiarism checker alone justifies at least one month's subscription before any major submission.
