First Impressions & Personal Experience
I tested Grammarly across several platforms: Chrome extension, Microsoft Word plugin, and the Grammarly desktop app. First-time setup took less than five minutes, with a guided onboarding process that felt modern and beginner-friendly.
Upon first use, Grammarly instantly highlighted issues in real-time, without being intrusive. I appreciated the side panel, which cleanly displayed suggestions categorized by correctness, clarity, tone, and engagement.
When rewriting a marketing email draft, Grammarly’s suggestions felt intelligent and subtle, unlike many AI tools that rewrite text too aggressively. However, I noticed that its tone detector occasionally misread sarcasm or informal phrases. Still, it was more of a quirk than a deal-breaker.
Core Features & Real-World Performance
1. Grammar and Spell Check
Grammarly remains a leader in this category. It picks up on advanced grammar issues, like incorrect verb forms or dangling modifiers, better than native spellcheckers in Word or Google Docs. In practical use, I found it especially helpful for catching errors in long-form writing.
What works: Accurate, fast, and minimal false positives.
What doesn’t: Overzealous correction of informal writing or regional phrases.
2. Tone Detection
Tone detection has improved with Grammarly’s AI upgrades. It evaluates whether your writing comes off as confident, friendly, or forceful.
Use case: Before sending client emails, I ran them through Grammarly to ensure the tone aligned with my intention.
What works: Useful feedback for business and academic writing.
What doesn’t: Less effective with humor, irony, or creative content.
3. AI Rewrites and Suggestions
This is Grammarly’s response to tools like ChatGPT and Jasper. You can now highlight sentences and get AI-powered rewrites for clarity or fluency.
Use case: Polishing dense or awkward phrasing in reports.
What works: Rewrites are context-aware and often better than the original.
What doesn’t: Lacks flexibility – no way to tweak or rewrite goals beyond clarity.
4. Plagiarism Checker
Available only on Premium, Grammarly scans billions of web pages to flag copied content.
Use case: Checking freelance submissions or academic work.
What works: Fast and accurate scanning.
What doesn’t: No citation recommendations or source comparison like Turnitin.
5. Multiplatform Integration
Grammarly works across Chrome, Firefox, Edge, Safari, MS Word, Google Docs, and its own desktop app. Mobile support is available through the Grammarly Keyboard.
What works: Seamless syncing and in-context corrections.
What doesn’t: Google Docs integration still lags behind others in speed.
User Experience (UI/UX)
Grammarly’s UI is sleek and minimalist. The sidebar UI is consistent across apps and browsers, and the suggestion cards are color-coded and easy to understand. Whether you’re writing an essay or a Slack message, the interface feels native, not bolted on.
Beginner-Friendly? Absolutely. Even first-time users can navigate and apply suggestions with zero training.
Standout UX Feature: The ability to set writing goals (audience, formality, intent) and receive tailored feedback is both powerful and intuitive.
Pricing: Is It Worth It?
Grammarly Plans (as of 2025):

Value vs. Competitors
Compared to ProWritingAid or Quillbot, Grammarly is pricier, but also more refined in UI and integrations. If you’re a student or casual writer, the free plan might suffice. For professionals or teams, the Premium or Business plan justifies the cost through time saved and improved output quality.
Verdict: Premium is worth it if writing is central to your work or brand.
