• Custom style guides for brand consistency

Cons

Grammarly’s Strengths

1. Best-in-Class Grammar Checking

Grammarly is renowned for its precision in spotting grammar, punctuation, and spelling errors. In a test using a 700-word blog with intentional mistakes, it flagged 98% of them and provided clear explanations that improved the Flesch-Kincaid readability score from 50 to 65. Users on Trustpilot (4.6/5) especially appreciate its accuracy, particularly for non-native English speakers.

2. Real-Time Tone & Style Suggestions

Grammarly adjusts tone to suit different writing goals (e.g., confident, friendly, professional). In a test email, it suggested replacing “I think” with “I’m confident,” aligning with business communication best practices. Business users can also upload style guides for consistent brand messaging—a key advantage for marketing teams.

---

3. Seamless Integration

Grammarly integrates smoothly with Google Docs, Microsoft Word, Gmail, and social platforms via browser extensions. Real-time edits make it an ideal companion for multi-platform writing. It caught multiple errors in a LinkedIn post draft that would have otherwise gone unnoticed.

---

4. AI Paraphrasing & Content Generation

Grammarly’s generative AI can rewrite paragraphs and create original content from prompts. A test using a 200-word product description yielded a polished draft suitable for social media. While outputs may require minor edits, they are SEO-friendly and highly usable for short-form marketing content.

Grammarly’s Weaknesses

1. Premium Pricing

At $30/month (or $144/year), Grammarly is pricier than competitors like QuillBot ($14.99/month) and Writesonic ($13/month). While the free plan is adequate for casual users, many of its best features—style guides, tone rewrites, and plagiarism checking—are locked behind the premium tier.

---

2. Over-Suggestions in Creative Work

For fiction or nuanced writing, Grammarly can be intrusive. It flagged stylistic choices like sentence fragments in a 500-word short story, echoing criticisms from PCMag. Writers may need to selectively ignore suggestions to preserve voice and tone.

---

3. Limited Plagiarism Detection

Though Grammarly checks content against billions of web pages, its plagiarism detection is less reliable for academic or gated content. In testing, it missed citations found by Turnitin and Copyscape. Good for casual use—but not for academic rigor.

---

Other Noteworthy Features

Citation Generator

Supports APA, MLA, and Chicago styles. Accurate but less automated than QuillBot’s citation tool. Valuable for students who don’t mind manual input.

Generative AI

Can produce emails, outlines, and social media posts from prompts. Great for short-form content, though long-form generation is better handled by tools like Jasper or Writesonic.

Tone Detection

Adjusts formality and friendliness in customer service replies or professional messages—helpful for client emails and public-facing communications.
