Grammarly has dominated the writing tool space for years, and with AI evolving at lightning speed, it’s now more powerful than ever.
But in 2025, with free alternatives like ChatGPT, and built-in grammar editor tools everywhere—is it still worth paying for?
This is why, we put Grammarly to the ultimate test: Does it actually improve your writing, or is it just another overpriced AI gimmick?

As a non-native English speaker who's written for Forbes as a council member in the past and built a successful career in global markets, I've been there. And after 10 years of daily Grammarly use, processing millions of words across 15+ platforms, I'm here to share what you really need to know about this AI writing assistant.
Quick Answer:

With GrammarlyGO’s AI improving contextual writing, better mobile integration, and advanced analytics, it’s a powerful tool for non-native speakers, professionals, and content creators. However, if you write infrequently, the free version might be enough.

What's New in Grammarly 2025?
Grammarly has evolved significantly from its grammar-checking roots. The latest version includes a much powerful AI-Powered Writing Assistant:

- GrammarlyGO integration for AI-powered writing suggestions
- Enhanced context understanding through machine learning
- Real-time writing style adaptation based on your audience
In my testing, GrammarlyGO has proven particularly impressive in understanding nuanced writing contexts.
For instance, when drafting a technical email to a client versus a casual team update, the AI automatically adjusts its suggestions to match the required tone and formality level.
What's particularly noteworthy is how the system learns from your writing patterns. After about two weeks of regular use, I noticed the suggestions becoming increasingly personalized to my style.
It started recognizing my common phrases and industry terminology, reducing false positives by approximately 60% compared to the first week of use.
The real breakthrough comes in how it handles multilingual nuances. As a non-native speaker, I often think in my native language and translate mentally. GrammarlyGO has become surprisingly adept at identifying these translation-based patterns and suggesting more natural English alternatives.
Enhanced Mobile Experience
- Seamless cross-device sync
- Improved keyboard integration on iOS and Android
- Native app performance optimizations
Having tested both iOS and Android versions extensively, I've found the mobile experience has finally caught up with desktop in 2025. The keyboard no longer lags on complex documents - a major improvement from earlier versions.
What impressed me most was how the mobile app handled context switching between professional and casual writing. When jumping from a work email to a social media post, the suggestions adjust instantly. This alone saved me about 15 minutes daily in editing time.
However, sometimes spelling suggestion tool broke the sentence and bigger words and started rewriting the words while picking up from the middle. But that issue was not native to the Grammarly editor.
Advanced Analytics Dashboard
- Detailed writing statistics
- Personalized improvement recommendations
- Writing goals tracking and progress reports
The analytics dashboard has become surprisingly useful for professional development. It tracks improvement patterns over time and identifies specific areas where you consistently make mistakes. In my case, it helped identify a persistent issue with preposition usage that I wasn't aware of.
Comprehensive Features Breakdown and Review
Core Writing Improvements

During my recent software documentation project, this saved me countless manual overrides.

After analyzing my writing patterns, it even created custom rules for my common technical terms.

Premium Features Deep-Dive
Advanced Grammar Detection
The premium version catches 400+ types of advanced grammar mistakes, including:
- Subject-verb agreement in complex sentences
- Proper modifier placement
- Consistent tense usage
- Article usage optimization
During my recent technical documentation sprint, I discovered how the advanced detection adapts to specific writing contexts. When writing documentation, it automatically recognized technical terms and adjusted its suggestions accordingly. This context-awareness prevented roughly 40% of false positives I used to get with earlier versions.
What's particularly impressive is the handling of complex sentence structures. In a recent 10,000-word white paper, it caught subtle agreement errors in sentences with multiple dependent clauses - something even human editors occasionally missed in my experience.

Platform-Specific Performance
Grammarly Browser Extension Review
- Chrome: Excellent integration, occasional memory usage spikes
- Firefox: Stable performance, slightly delayed suggestions
- Safari: Limited features compared to Chrome version
- Edge: Native integration with Microsoft ecosystem
In my daily workflow testing, Chrome's extension proved most reliable with Google Workspace tools, though it does consume about 200-300MB of RAM when actively checking longer documents. The Edge extension surprisingly outperformed others in Microsoft Office Online, with near-instant suggestions and minimal resource usage.
Firefox users will appreciate the latest memory optimization update but complex suggestions still take 1-2 seconds longer to appear compared to Chrome. Generally that shouldn't be an issue since you will have plenty of available memory if you are using a MacBook.
Desktop Apps
- Windows: Robust performance, full feature set
- macOS: Native feel, superior integration with Apple ecosystem
- Linux: Limited support through browser extensions only
Mobile Experience
- Grammarly iOS keyboard:
- Keyboard integration works seamlessly
- Smart suggestions appear instantly
- Battery impact is minimal
- Grammarly on Android review:
- Custom keyboard functionality
- Background performance optimizations
- Integration with popular apps
Real-World Usage Scenarios
Professional Writing
As a Forbes contributor, I've relied on Grammarly for:
- Article proofreading
- Style consistency
- Tone adjustment for different publications
- Deadline-driven editing
The real test came during a week when I had to submit three different articles to three different publications. Each had distinct style guidelines and tone requirements. Grammarly's ability to maintain separate style guides for each publication saved me hours of manual checking.
A particularly useful discovery was the custom style guide feature for different clients. I created specific rules for each publication's preferences (Oxford comma, number formatting, etc.), which reduced editing time by approximately 35%.
Here are a few areas where you will find Grammarly premium incredibly useful.
Academic Writing
- Research papers
- Thesis writing
- Citation formatting
- Plagiarism prevention
Business Communication
- Email composition
- Report writing
- Presentation reviews
- Social media posts
Pricing Analysis
Free vs Premium
- Free: Basic grammar and spelling
- Premium: $12-30/month depending on plan
- Business: Custom pricing for teams
Value Proposition
- Time saved per document: ~20 minutes
- Error reduction rate: 76%
- Professional impact: Measurable improvement in response rates
In tracking my own usage over three months, I found the most significant time savings came from the automated citation checker and style guide enforcement which comes for free with Grammarly premium. For a typical 2,000-word article, Grammarly reduced editing time from 90 minutes to about 45 minutes.
The error reduction rate is particularly impressive for non-native speakers. In a recent analysis of my writing team's work, members using Grammarly Premium showed a 76% lower error rate in their first drafts compared to those using the free version.
Grammarly cons to note down
Technical Constraints
- Occasional false positives
- Limited support for some specialized terminology
- API rate limits for developers
- Platform-specific feature availability
Real-world testing revealed that most false positives occur with industry-specific jargon and compound technical terms. It does not recoganize many tools specific to my industry including popular acronyms. Creating a custom dictionary will reduce this error.
Use Case Limitations
- Creative writing may require manual override
- Technical documentation needs additional review
- Code snippets often flagged incorrectly
- Some language pairs have limited support
The language pair support remains a challenge for non-native speakers. While English-Spanish translations show high accuracy, less common language pairs like English-Hindi often require additional manual review. In my testing, most of idioms and colloquialisms needed human intervention. So if you need Grammarly for translation, it might not be the right tool to fully rely upon.
Grammarly Alternatives Review
ProWritingAid
- More detailed reports
- Better for long-form content
- Lower price point
- Slower performance
Having tested ProWritingAid alongside Grammarly for 5 months, I found its detailed reports excellent for book-length projects. However, its performance lags significantly - taking up to 45 seconds to analyze a 5,000-word document compared to Grammarly's 10-15 seconds.
Also, false positives are much higher for PWA than Grammarly.
The style analysis tools go deeper than Grammarly's, offering 20+ different reports. However, this depth comes at the cost of usability - many users find the wealth of information overwhelming rather than helpful.
Here are some other tools I checked quickly for comparison.
Hemingway Editor
- Focus on readability
- One-time payment
- Limited features
QuillBot
- Strong paraphrasing
- AI writing capabilities
- Limited grammar checking
