What Grammarly does well
Grammarly is the tool you install once and forget about until it saves you. It works in email, docs, social posts, and messaging — catching the typo, the wrong “their,” the sentence that reads ruder than you meant. The Pro tier’s full-sentence rewrites and tone adjustments genuinely improve writing rather than just flagging errors, and the plagiarism and AI-text detection matter for students, publishers, and anyone whose work gets scrutinized.
After the 2025 rebrand (parent company now Superhuman Platform Inc.), the old Premium/Business split collapsed into a single Pro plan, which simplified the choice: free for basic correction, Pro for the full assistant.
What Wordtune does well
Wordtune solves the most common writing problem there is: the sentence that’s almost right. Highlight it, and Wordtune offers a spread of alternatives — shorter, more formal, more casual, more confident. For non-native English speakers and anyone who writes marketing copy, emails, or social posts, that “try another version” loop is addictive and genuinely productive.
It’s also the cheaper buy. The free tier’s 10 rewrites a day covers occasional use, and the paid tiers cost less than Grammarly Pro while removing the rewrite limits entirely.
The verdict: which should you pick?
Pick Grammarly if you want one tool watching everything you write — correctness, clarity, tone, and originality. It’s the complete package, especially the free tier.
Pick Wordtune if your writing is already correct and you need better phrasing — more natural sentences, the right tone, sharper copy. It’s the best pure rewriter at this price.
Use both if you’re a heavy writer: Grammarly free for proofreading everywhere, Wordtune for the sentences that need reworking. They overlap less than you’d think.
Grammarly vs Wordtune: FAQ
Is Wordtune free?
Yes — the free plan includes 10 rewrites per day and 3 AI summaries per month, which covers light use. Paid plans start around $6.99/month billed annually.
Is Grammarly worth paying for?
For professionals, yes — Pro at $12/month billed annually adds full-sentence rewrites, tone control, plagiarism and AI-text detection, and 2,000 AI prompts a month. Casual writers do fine on the free tier.
Can Wordtune replace Grammarly?
No. Wordtune rewrites sentences beautifully but isn’t a proofreader — it won’t systematically catch grammar mistakes across your documents. Grammarly does that; they’re complementary.
Which is better for non-native English speakers?
Wordtune for phrasing — its rewrite suggestions teach you more natural English. Grammarly for correctness — it explains the errors. Many learners run both.
