Quick verdict: Grammarly and Wordtune look alike and are not. Grammarly is a correctness layer that follows everything you type — grammar, clarity, tone, a plagiarism checker — for $12/mo billed yearly (Pro). Wordtune is a rewriting specialist: it makes sentences read better — rephrases, tone shifts, shorten/expand — without pretending to be a full grammar engine, and its Unlimited plan is $6.99/mo billed yearly, nearly half Grammarly’s price. Buy Grammarly if writing correctness across email, docs and apps is the job; buy Wordtune if your drafts are grammatically fine but sound flat; buy neither if a $17–20/mo chatbot already covers your editing — a real possibility we get to below.

Round 1: The job each tool actually does
Grammarly’s center of gravity is error elimination with context: it watches your typing across the whole computer, flags grammar/punctuation/clarity issues, suggests full-sentence rewrites, detects tone, and checks plagiarism against web sources. Wordtune’s center of gravity is expression: highlight a sentence and it offers alternative phrasings — casual or formal, shorter or expanded — plus a summarizer (Wordtune Read) for documents and videos. Wordtune’s free tier includes unlimited basic spelling/grammar checks, but depth-correctness is Grammarly’s game; if your problem is “this paragraph is correct but lifeless,” Wordtune is the surgical tool.
Winner: Grammarly for correctness breadth; Wordtune for sentence-level style. It genuinely depends which problem you have.
Round 2: Price — the specialist undercuts the platform
Grammarly Pro is $12/mo billed yearly (or a steep $30 month-to-month). Wordtune’s ladder is lower at every rung: Advanced $4.89/mo billed yearly (30 rewrites/day, 15 summaries/mo) and Unlimited $6.99/mo billed yearly — unlimited rewrites and summaries, vocabulary/fluency enhancements — the tier most buyers should compare against Grammarly Pro, at 58% of its price. (Wordtune’s monthly-billing figures are inconsistent across sources; annual is the sane way to buy it anyway. Its 3-day trial demands payment details upfront — set a reminder.)
Winner: Wordtune, clearly — you’re paying for one craft, not a platform.
Round 3: AI allowances and the free tiers
Grammarly meters its generative AI: 100 prompts/mo free, ~2,000/mo on Pro — plenty for assisted drafting, finite by design. Wordtune meters by day on lower tiers (10 free rewrites/day; 30/day Advanced) and removes the meter on Unlimited. For pure rewriting volume, Wordtune Unlimited is the only genuinely unmetered product in this comparison. Both free tiers are auditions: Grammarly’s shows you the checking layer; Wordtune’s shows you the rewrite quality.
Winner: Wordtune for rewriting volume; Grammarly for assisted drafting breadth.
Round 4: Coverage — everywhere vs where-you-compose
Grammarly runs as a system layer: browser extension, desktop apps with an overlay on other apps, mobile keyboard, Office add-ins. Wordtune covers the browser, Word and its own editor plus iOS — the places long-form writing happens, but not your whole machine. If your writing is 90% in Docs/WordPress, Wordtune’s coverage suffices; if it’s scattered across Slack, email, CRM notes and three browsers, Grammarly’s omnipresence is the feature.
Winner: Grammarly, and it isn’t close.
The verdict
- Pick Grammarly if you write professionally everywhere and want one correctness layer + plagiarism checks: Pro, $12/mo billed yearly. It’s also the proofreading slot in our freelancers roundup.
- Pick Wordtune if your grammar is fine but your sentences need a voice — bloggers, newsletter writers, ESL professionals polishing expression: Unlimited, $6.99/mo billed yearly.
- Pick neither (yet) if you already pay for Claude or ChatGPT and your editing is occasional: both chatbots rewrite and proofread well inside a chat window, as our bloggers’ writing guide covers. What you give up is the in-place, everywhere-you-type layer — decide if that layer is worth $7–12/mo to you. For daily professional writers, it usually is.
FAQ
Is Wordtune better than Grammarly?
At rewriting, yes; at everything else Grammarly does, no. They’re adjacent tools with one overlapping feature. If forced to own one: Grammarly for professional correctness across apps, Wordtune for making drafted prose sound human and varied — at nearly half the price.
Does Wordtune check plagiarism?
No — that’s a clean Grammarly Pro advantage (and a reason students and content teams standardize on it). Wordtune has no originality checker as of October 2026.
Can I use both?
Some writers do — Grammarly as the always-on safety net, Wordtune for deliberate rewrite passes on important pieces. Combined annual cost is ~$19/mo billed yearly; only worth it if writing is billable work for you.
What about the free tiers for real work?
Grammarly free is usable indefinitely as a basic checker (it’s how millions use it). Wordtune free’s 10 rewrites/day suits occasional polish, not daily publishing — treat both as evaluations unless your volume is truly tiny.
