From comma splices to subject-verb agreement and misplaced modifiers, Grammarly catches them all.

Far more advanced than typical word processors, it even flags context-specific spelling errors (e.g., “there” vs. “their”).

It helps eliminate wordy phrases and redundancies, making your writing more direct and impactful.

Offers suggestions for more impactful, accurate, or captivating word choices, significantly refining your writing style.

Grammarly analyzes your writing and provides an instant tone assessment (e.g., confident, joyful, assertive, concerned). This feature is valuable for ensuring your message lands exactly as intended, whether you’re writing a formal business proposal or a casual social media post. Moreover, With GrammarlyGO, you can now actively change your tone with AI prompts.

This is the game-changer for Grammarly in 2025. Once enabled, GrammarlyGO seamlessly embeds AI capabilities into your writing process, empowering you to:

Provide a simple prompt (e.g., “Write an email requesting a meeting,” “Draft a blog post outline on sustainable living”), and GrammarlyGO will create a starting point for you.

Don’t like how a sentence sounds? Instead, ask GrammarlyGO to rewrite it for clarity, conciseness, formality, or a completely different tone.

Moreover, instantly condense long documents or emails into key takeaways.

Stuck on a topic? Then, leverage AI to spark new ideas, structure your content with ready-made outlines, and craft compelling headlines that grab attention.

Beyond detecting tone, GrammarlyGO can actively adjust the tone of your text (e.g., make it more confident, friendly, empathetic, or formal). You can even set a custom voice profile.

The AI understands the surrounding text, providing more relevant and helpful suggestions than ever before. This functionality is a key aspect of this Grammarly review.

The plagiarism checker, a crucial feature particularly for students, academics, and content creators, leverages a vast database encompassing billions of web pages and academic sources. Consequently, it highlights passages that might be unoriginal and provides source citations, helping you avoid unintentional plagiarism. In 2025, with the rise of AI-generated content, Grammarly has also introduced Grammarly Authorship to help identify a content’s origin, which is a significant step towards promoting digital integrity. Furthermore, you can explore robustness of Grammarly’s Plagiarism Checker and its value against QuillBot in the Grammarly vs QuillBot accuracy and performance analysis.

Grammarly’s true power lies in its ubiquity because it integrates seamlessly into nearly every platform where you write. For instance:

• Browser Extensions: Chrome, Edge, Safari, Firefox.
• Desktop Apps: For Windows and macOS.
• Microsoft Office Add-in: For Word and Outlook.
• Google Docs Compatibility: Provides immediate, on-the-fly writing suggestions directly as you compose in your Google Docs.
• Mobile Keyboards: For iOS and Android, bringing Grammarly’s power to your smartphone.

For teams and businesses, Grammarly offers robust features to ensure consistent brand voice. You can upload custom style guides and define brand tones. As a result, Grammarly will provide suggestions that keep all team members on-brand, no matter who is writing. This is crucial for maintaining a professional and unified external presence.

Grammarly provides a weekly email report summarizing your writing performance, common errors, and areas of improvement. Consequently, this feedback loop is an excellent tool for continuous learning and refining your writing skills over time.

Grammarly has just launched its new AI Humanizer feature, available under the Pro version. I tested it personally, and it’s a solid addition to Grammarly’s growing toolset. Once you write your text, you can click on the “Humanize” option to choose from several pre-built voice templates such as Neutral, Concise, Formal, Clear, Crisp, Assertive, and Objective.

Moreover, you can even train it with your own writing style, by providing 3 to 4 text samples, Grammarly’s AI learns your tone and saves it for future use. Once you select a preferred writing style, your text is instantly converted in that tone with impressive natural flow.

While highly effective, no digital assistant offers a flawless experience, and Grammarly, too, has its areas for improvement. Therefore, here’s a balanced look at its advantages and disadvantages based on its 2025 capabilities as observed in this Grammarly review:

Pros (+)	Cons (-)
Exceptional Core Correction: Catches more errors than built-in checkers.	Premium Price: Can be expensive for individuals on a monthly plan.
Powerful Generative AI (GrammarlyGO): Speeds up content creation & rewriting.	AI Nuance: AI outputs may sometimes lack deep creative nuance or human touch.
Extensive Integrations: Works almost everywhere you write.	Over-reliance Risk: Can hinder independent writing skill development if misused.
Real-time Feedback: Instant suggestions as you type.	Plagiarism Checker Limitations: While strong, no checker is 100% foolproof for novel content.
Tone Detection & Adjustment: Helps tailor your message for impact.	Internet Connection Required: Most features need an active connection.
User-Friendly Interface: Easy to learn and navigate.	Occasional Over-Correction/Incorrect Suggestions: Still an AI; human review is always best.
Plagiarism Checker Included: A valuable added layer of security.	Not a Human Editor Replacement: Cannot replicate the critical thinking or deep understanding of a human proofreader.
Continuous Updates & Innovation: Regularly adds new features and improves AI.

While Grammarly is a leader, several strong alternatives offer similar or complementary features:

A versatile generative AI writing tool that helps create a wide range of content, from blog posts and articles to ads and product descriptions. It offers numerous templates and is a strong competitor in the AI content generation space.

Often considered Grammarly’s closest competitor, ProWritingAid offers more in-depth reports and tools for fiction writers, though its interface can be less intuitive.

A more affordable and user-friendly generative AI writing assistant. It’s a good option for individuals or small businesses seeking AI assistance for various content types without a high price tag.

Powerful general-purpose AI chatbots that can assist with writing, brainstorming, and editing, but lack the seamless, real-time integration across platforms that Grammarly offers.

Microsoft’s built-in writing assistant, continuously improving but generally less comprehensive than Grammarly’s paid versions.

This tool specifically targets clarity and conciseness, drawing attention to intricate sentence structures and instances of passive voice. A great supplementary tool.

Choosing an alternative often depends on your primary need: deep editing (ProWritingAid), rapid content generation (Jasper), or quick rephrasing (QuillBot). However, for a comprehensive, all-in-one writing assistant that integrates everywhere, Grammarly remains a top choice.

Getting started is easy. In fact, using Grammarly is incredibly intuitive, designed to fit seamlessly into your existing writing habits.

• Visit the Grammarly website and create an account (you can start with the free version).
• Download the browser extension (e.g., for Chrome) and the desktop app for your operating system. You can also get the mobile keyboard.

• Open your email client, Google Docs, Microsoft Word, or simply start typing in any text field online.
• Alternatively, open the Grammarly desktop app or the Grammarly web editor and paste your text directly.

• As you write, Grammarly will underline errors and suggest improvements in real-time.
• Specifically, red underlines indicate correctness issues (grammar, spelling).
• Meanwhile, blue underlines suggest clarity and conciseness improvements.
• In addition, green underlines highlight engagement and delivery issues.
• Finally, purple underlines point to tone suggestions.

• Click on an underlined word or phrase to see Grammarly’s suggestion and a brief explanation.
• You can accept the suggestion with a click, dismiss it, or learn more about the rule.
• For instance, for generative AI prompts (GrammarlyGO), simply highlight text or type a command, and Grammarly will provide options.

• Before you start, select your writing goals (e.g., audience, formality, domain) from the sidebar. This functionality enables Grammarly to provide highly personalized suggestions, directly aligning with your unique writing situation.

Grammarly acts as an intelligent co-pilot, guiding you toward better writing while keeping your flow uninterrupted.

8.1 Is Grammarly really free?

Yes. In fact, Grammarly offers a robust free version with essential grammar, spelling, and punctuation checks, along with limited generative AI prompts. A large segment of users consider this ample for their foundational purposes.

8.2 Does Grammarly detect plagiarism?

Yes, but the plagiarism modules still need improvement. Moreover, the Grammarly Pro (paid) and Enterprise plans include a plagiarism checker that compares your text against billions of web pages and academic sources.

8.3 Is Grammarly safe and private?

Accordingly to the company, Grammarly strongly commits to protecting user data and upholding privacy standards. They use industry-standard encryption, comply with GDPR and CCPA, and state that they do not sell user data or use it to train third-party models.

8.4 Does Grammarly work with Microsoft Word/Google Docs?

Absolutely, Grammarly offers dedicated add-ins for Microsoft Word and Outlook, and a seamless integration with Google Docs via its browser extension.

8.5 Can Grammarly generate full articles?

While GrammarlyGO can generate outlines, sections, and rewrite substantial passages, it’s primarily designed as an assistant to enhance existing content or kickstart ideas, rather than a standalone long-form article generator like some dedicated AI writing tools.

8.6 What is the difference between Grammarly Premium and Grammarly Pro?

In essence, Grammarly Premium and Grammarly Pro refer to the same individual paid plan. Grammarly transitioned its naming from “Premium” to “Pro” to better reflect the expanded and more advanced features, particularly the integration of cutting-edge generative AI capabilities (GrammarlyGO) beyond just basic grammar checking. So, if you’re looking for Grammarly Premium, you’re looking for Grammarly Pro.

8.7 Is Grammarly better than other tools like Jasper AI or ProWritingAid?

It depends on your specific needs. Grammarly is generally favored for its comprehensive real-time grammar/style checking and wide integration. When it comes to academic reporting, ProWritingAid might be stronger. Those focusing on pure content generation, Jasper or Copy.ai might offer more features.
