Grammarly has been one of the most widely used writing assistants for over a decade. What started as a simple grammar checker has evolved into a powerful AI-driven writing tool that helps millions of people write clearer, more professional, and more polished content every day. But now that advanced AI models like ChatGPT-5 exist, many people are asking the same question: is Grammarly still worth it in 2025?
In this review, I will break down everything you need to know about Grammarly. I will compare the free and premium versions, show practical examples, explain how it compares to ChatGPT-5, and help you decide if it is still the right tool for your needs. As someone with both a Bachelor’s and a Master’s degree in Artificial Intelligence, I bring more than just surface-level impressions. My goal is to give you a clear, informed perspective on whether Grammarly is a tool you should invest in today.
What is Grammarly?
Grammarly is an AI-powered writing assistant designed to improve your writing quality in real time. It checks grammar, spelling, punctuation, tone, and clarity. It can also detect plagiarism and provide AI-powered rewrites, making it far more than just a simple spell checker.
One of Grammarly’s strengths is its wide availability. It can be installed as a browser extension, used in Microsoft Word, integrated into Google Docs, or downloaded as a desktop and mobile app. This makes it easy to use Grammarly wherever you write.
Over the years, Grammarly has shifted from being a reactive grammar checker into an intelligent tool that actively improves the flow, tone, and persuasiveness of your writing.
Grammarly Free Plan: What You Get
The free version of Grammarly gives you access to the core features that most people expect. These include:
-
Grammar and spelling corrections
-
Basic punctuation checks
-
Suggestions for clarity improvements
-
A tone detector that helps you identify whether your text sounds friendly, formal, or casual
-
A limited number of AI prompts to rewrite or adjust small sections of text
The free plan is very useful for catching basic mistakes, especially for casual users who want something better than the default spell checker in Word or Google Docs.
However, it has clear limitations. It does not provide advanced clarity suggestions, vocabulary improvements, or full rewrites. You also cannot access the plagiarism checker on the free plan, which can be a dealbreaker for students and professionals.
Example with Grammarly Free
Let’s take a simple text:
“The report is good but it can be better if we fix some parts and make it more clear.”
Free Grammarly will correct this into:
“The report is good, but it can be better if we fix some parts and make it clearer.”
This is helpful, but it only addresses basic grammar and punctuation. The structure and flow of the sentence still feel clunky. That is where Grammarly Premium comes in.
Grammarly Premium: Features and Benefits
The premium version of Grammarly unlocks all of its advanced tools. This is where it moves beyond a grammar checker and becomes a true writing assistant.
Key premium features include:
-
Advanced clarity and conciseness rewrites
-
Tone adjustments for formality, confidence, and engagement
-
Vocabulary enhancement suggestions
-
Unlimited AI rewrites and paraphrasing
-
Full plagiarism detection, scanning billions of web pages and academic databases
-
Additional AI features such as summarizing or expanding text
Example with Grammarly Premium
Using the same sentence from earlier:
“The report is good but it can be better if we fix some parts and make it more clear.”
Grammarly Premium suggests:
“The report is solid, but it could be improved by refining certain sections for greater clarity.”
The difference is obvious. Premium does not just fix grammar, it reshapes the sentence to be more professional, concise, and polished. This is the type of difference that stands out in academic writing, business communication, and content creation.
Grammarly vs ChatGPT-5 in 2025
One of the most common questions people ask now is: if ChatGPT-5 exists and can write entire essays, articles, and emails, do we even need Grammarly anymore?
The answer is yes, but for different reasons. ChatGPT-5 is excellent for generating new content, brainstorming ideas, and even rewriting text in creative ways. However, it is not designed to work inside your writing process in real time. Grammarly integrates directly into your email client, word processor, and browser to catch mistakes and improve clarity as you write.
Think of ChatGPT as a content generator and Grammarly as a quality control editor. They complement each other rather than replace one another. In fact, many professionals use both: generate ideas or drafts with GPT-5, then polish the final draft with Grammarly before sending it out.
Who Should Use Grammarly?
Grammarly is still highly relevant in 2025, but it is most useful for certain groups of people.
Students benefit from both grammar corrections and the plagiarism checker. This can prevent accidental plagiarism and improve essay quality.
Professionals use Grammarly to ensure emails, reports, and client-facing documents are error-free and confident in tone.
Content creators and marketers use it to polish blog posts, video scripts, and newsletters, ensuring their content reads smoothly.
Non-native English speakers gain the most value. Grammarly helps with clarity, tone, and word choice, which can make writing in English much more natural and persuasive.
Grammarly Pricing in 2025
Grammarly offers three main pricing options:
-
Free plan: $0 forever with basic corrections
-
Premium plan: Around $12 per month when billed annually (prices vary slightly by region)
-
Business plan: A team-focused subscription with collaboration tools and analytics
For most individuals, the Premium plan is the right choice. The improvements in clarity and tone alone can justify the cost if you write frequently.
