Grammarly and Wordtune are both writing assistants, but they emphasize different parts of the writing process. Grammarly is a comprehensive editor: grammar, spelling, punctuation, clarity, tone, and now AI-powered drafting. Wordtune is a rewriting specialist: it takes your existing sentences and offers alternative phrasings, summaries, and expansions.
Think of Grammarly as a proofreader who also writes. Think of Wordtune as a co-writer who rephrases what you’ve already said. The overlap is growing (both are adding AI features), but the core strengths are still distinct.

|---|---|---|
| Free | Grammar/spelling/punctuation | 10 rewrites/day, 3 AI generations |

Grammarly’s free tier is more useful day-to-day — you get unlimited grammar and spelling corrections, which is enough for many users. Wordtune’s free tier caps you at 10 rewrites per day, which runs out fast if you’re actively editing.
At the premium level, Wordtune is slightly cheaper, but Grammarly gives you significantly more: clarity suggestions, tone detection, full-sentence rewrites, plagiarism checking, and GrammarlyGO for AI drafting. For the $2/month difference, Grammarly Premium is denser with value.
Where Grammarly Wins
Comprehensive Error Catching
Grammarly catches the full spectrum of writing issues: grammar, spelling, punctuation, subject-verb agreement, article usage, comma splices, passive voice, wordy sentences, and more. The suggestions include explanations, so you actually learn from the corrections.
For non-native English speakers, students, and professionals who write a lot of formal content, this comprehensive coverage is invaluable. Wordtune doesn’t focus on error correction — it assumes your grammar is already decent and focuses on rephrasing.
Platform Coverage
Grammarly works almost everywhere: Chrome, Firefox, Safari, Edge, desktop apps for Mac and Windows, a mobile keyboard for iOS and Android, Microsoft Office, Google Docs, Gmail, Slack, and more. It’s deeply integrated into the writing surfaces people actually use.
Wordtune’s reach is narrower: Chrome and Edge extensions, a Google Docs integration, and a Microsoft Word add-in. No desktop app, no mobile keyboard, no Firefox or Safari extension. If you write across many platforms, Grammarly covers more ground.
Tone Detection and Adjustment
Grammarly analyzes your text and tells you how it reads: “Your text sounds Formal and Confident” or “This may come across as Slightly Accusatory.” You can then adjust toward your intended tone. This is genuinely useful for emails, client communications, and anything where tone matters.
Wordtune offers a simpler Casual/Formal toggle for rewrites, but it doesn’t analyze or report on the overall tone of your writing.
Plagiarism Checking
Grammarly Premium includes a plagiarism checker that compares your text against billions of web pages. Useful for students, content writers, and anyone who needs to verify originality. Wordtune doesn’t offer this.
Team Features
Grammarly Business ($15/user/month) includes style guides, brand tones, and admin analytics. You can define company-specific terminology, preferred phrasing, and tone guidelines that apply across the team. For organizations that care about consistent communication, this is a real feature. Check Grammarly’s pricing for the full breakdown.
Wordtune’s team plan exists but lacks style guide functionality.
Multi-Language Support
Grammarly has expanded beyond English with beta support for German, French, Spanish, Portuguese, and more. It’s not as polished as the English experience yet, but it’s there. Wordtune is English-only.
Where Wordtune Wins
Sentence-Level Rewriting
This is Wordtune’s core competency. Highlight a sentence and get multiple alternative phrasings — shorter, longer, more formal, more casual. The rewrites are often surprisingly natural. For people who know what they want to say but struggle with phrasing, Wordtune’s rewriting engine is more focused than Grammarly’s equivalent.
Wordtune Read and Spices
Wordtune Read lets you upload documents or articles and get AI summaries — useful for processing research material. “Spices” lets you expand on a point, add a counterargument, or insert examples inline. Both features focus on augmenting your existing work rather than generating from scratch.
Price for Rewriting
If rephrasing is your primary need, Wordtune’s $9.99/month gives you unlimited rewrites at a lower price without grammar features you might not use.
Who Should Pick Which?
- Students and non-native speakers → Grammarly (grammar correction + plagiarism checker + learning from explanations)
- Professionals writing emails → Grammarly (tone detection + works in Gmail, Outlook, Slack)
- Content writers → Both have merit; Grammarly for error-catching, Wordtune for rephrasing. Pick one? Grammarly.
- Researchers and academics → Wordtune (summarization + paraphrasing for source material)
- Teams → Grammarly (style guides and brand tones make it the only real option)
The Verdict
Grammarly is the better all-around writing assistant. It catches more issues, works on more platforms, and covers the full writing workflow from grammar to tone to AI generation. Most people who need one writing tool should get Grammarly.
Wordtune is the better rewriting tool. If your grammar is solid but you want help saying things better, shorter, or differently, Wordtune’s focused approach delivers. It’s also the better choice for content summarization.
Some writers use both — Grammarly always on for error catching, Wordtune activated when they need to rework a specific passage. There’s no conflict running both browser extensions simultaneously.
