Both score 18/25. Here's who should pick which — and the data flag to read first. - Author: Adam - Tags: Writing & Content AI, Grammarly, QuillBot, #comparison Head-to-head verdict [**18**/25Grammarly](https://www.theaidirectory.com.au/grammarly-review-australia-2026/)[**18**/25QuillBot](https://www.theaidirectory.com.au/quillbot-review-australia-2026/) **No single winner.** The right choice depends on the job; the verdict below says who should buy which. *Pricing figures updated 6 September 2026: USD prices are converted at the current rate (1 USD ≈ 1.40 AUD, verified 5 September 2026) and shown ex-GST, replacing the retired 1.55 + GST basis. A GST-registered Australian business that supplies its ABN is not charged GST on an imported digital service; other buyers should allow \~10% on top (*[*Methodology*](https://www.theaidirectory.com.au/methodology/)*).* > **Winner: it depends on the job — and they're closer than they look.** **Pick Grammarly** if you want to catch errors and fix tone everywhere you type, across every app. **Pick QuillBot** if you mainly rephrase and tighten other people's words, and you want native AUD billing. Both score 18/25\. Read the data section before you commit either. > > *Last reviewed: 20 September 2026 by Adam.* > > **ℹ Vendor note — 20 September 2026: Grammarly is now part of Superhuman.** Grammarly's homepage says "Grammarly is now a part of Superhuman" and its footer reads "2026 © Superhuman Platform". The parent renamed itself from Grammarly to Superhuman on 29 October 2025\. **Nothing in this comparison changes** — Grammarly's prices, plans and data hosting are unchanged at our 20 September check, and Pro is still US$12/month on annual billing and US$30 month to month. The name on your invoice is Superhuman Platform. > > *Sources:* [*grammarly.com*](https://www.grammarly.com/?ref=theaidirectory.com.au) *·* [*grammarly.com/plans*](https://www.grammarly.com/plans?ref=theaidirectory.com.au)*. Read 20 September 2026\. Wayback: capture pending (archive.org unavailable 20 Sep 2026).* These two get lumped together as "AI writing tools," but they're built for different jobs. Grammarly is a correction-and-tone layer that follows you across every box you type into. QuillBot is a rephrasing-and-editing workbench you go *to*. Both now bundle a broader AI suite, both land on the same 18/25 score, and both have a real Australian catch. The right pick depends on whether you draft or edit — and how much you care where your text goes. ## At a glance | | Grammarly | QuillBot | | ------------------ | --------------------------------------- | --------------------------------------- | | **Our score** | 18/25 ⭐⭐⭐⭐ (AU Fit 2/5) | 18/25 ⭐⭐⭐⭐ (AU Fit 3/5) | | **Free tier** | Yes — grammar, tone, 100 AI prompts | Yes — paraphraser + grammar with limits | | **Paid (annual)** | \~A$17/mo ex-GST (US$12, billed yearly) | A$12.49/mo (native AUD) | | **Paid (monthly)** | \~A$42/mo ex-GST (US$30) | billed annually | | **Billing** | USD — watch the exchange rate | Native AUD | | **Core strength** | Errors + tone, everywhere you type | Paraphrasing + editing | | **Data residency** | AWS US East; no AU option | No AU option | | **The catch** | No AUD, no local support | Trains on your inputs by default | | **Best for** | Drafters who write across many apps | Editors who rephrase for a living | ## What both tools actually do **Grammarly** is a writing assistant that lives almost everywhere you type — email, your CRM, Google Docs, the browser — catching spelling slips, clumsy sentences and the wrong tone in real time, and now drafting and rewriting with generative AI on top. Its strength is ubiquity: it's the same helpful layer in every box. **QuillBot** started as a paraphraser and grew into a suite: a rewriter, grammar checker, summariser, translator, plagiarism and AI detector, citation generator, plus image and PDF tools. The paraphraser and grammar checker are the parts worth paying for; the rest is convenient rather than class-leading. You go to QuillBot to *work over* text you already have. ## Pricing in Australia This is QuillBot's clearest win. **QuillBot prices in native AUD.** Premium is **A$12.49/month billed annually**, localised to Australia — no USD conversion, no exchange-rate guesswork — and the free tier covers a lot of everyday rephrasing and proofing. The one thing it doesn't state is how GST is handled. **Grammarly bills in USD, and the casual rate stings.** Pro is US$12/month billed annually (about **A$17/month ex-GST**), US$20/month quarterly, or US$30/month month-to-month (about **A$42/month ex-GST**). You only get the good rate if you commit to a year, and the month-to-month price is steep for Australians paying FX on top. The free tier is genuinely useful; Pro adds full-sentence rewrites, one-click tone, 2,000 AI prompts/month, and plagiarism/AI detection. On price, QuillBot wins: lower headline number, billed in your own currency. Just know that the cheap Grammarly annual rate (\~A$17 ex-GST) is competitive *if* you commit for the year. ## Where Grammarly wins - **It works everywhere you type.** Email, CRM, Docs, the browser — the same correction-and-tone layer in every app. Nothing else matches that ubiquity for a drafter. - **Tone detection and real-time correction lead the category.** It catches the wrong tone in an email before you send it, not after. - **Stronger security credentials.** SOC 2 Type 2 and a full ISO suite, and Grammarly says it doesn't sell or monetise your content — a meaningfully better data-handling story than QuillBot's default. - **Generative AI and writing agents** are built in on Pro, with a 2,000-prompt monthly allowance that's generous for most. ## Where QuillBot wins - **Native AUD billing.** A$12.49/month, no FX, no exchange-rate surprise — the thing most US writing tools get wrong for Australians. - **Paraphrasing is its core competence.** If your day is rephrasing, tightening and editing other people's words — students, marketers, support teams — QuillBot's paraphraser and modes are the better-built tool for that specific job. - **A broader utility suite.** Summariser, translator, citation generator, plagiarism and AI detection, plus PDF tools — convenient extras bundled into one subscription. - **A slightly better Australian fit (3/5 vs 2/5)**, entirely on the strength of that native AUD billing. ## The data flag — read this before you buy QuillBot The single most important difference for a business handling client or confidential text: **QuillBot trains on your text inputs by default** unless you opt out in the browser extension. Grammarly doesn't monetise your content and carries the stronger certification stack (SOC 2 Type 2, full ISO suite). Neither offers Australian data residency — Grammarly hosts in AWS US East, QuillBot states no AU region — and neither offers local support. For an individual editing everyday writing, neither is a dealbreaker. For a regulated Australian organisation (legal, health, government) or anyone routing confidential client text, **read each tool's data terms first**, and turn QuillBot's training off before you paste anything sensitive. ## Which to pick — decision framework - **You draft across many apps and want errors and tone caught everywhere** → **Grammarly**. - **You mainly rephrase, tighten and edit existing text** → **QuillBot**. - **You want native AUD billing and the lowest headline price** → **QuillBot**. - **You handle confidential or client text and want the stronger data-handling story** → **Grammarly** (and avoid pasting sensitive text into either without checking the terms). - **You write for a living and will commit to an annual plan** → **Grammarly** at \~A$17/month ex-GST is the one to buy. ## The verdict **Winner: by job, not by knockout — both earn their 18/25.** For the typical Australian who writes a lot across email, documents and a CRM, **Grammarly** is the one to reach for first: the ubiquity, the real-time tone correction and the stronger data-handling story make it the safer everyday buy, and the annual rate (\~A$17/month ex-GST) is fair. Just go in knowing the bill is in US dollars and there's no Australian hosting. **QuillBot is the better tool for a specific, large group:** people who edit more than they draft, and who value native AUD billing. The paraphraser is genuinely good, the AU$12.49 price is honest, and the free tier is usable. The weak point isn't the price — it's the data terms: QuillBot trains on your inputs by default, so turn that off before you trust it with anything confidential. Pick on the job you actually do. Drafters who write everywhere: Grammarly. Editors who rephrase for a living and want AUD billing: QuillBot. Either way, start on the free tier — both are usable without paying, and a week of real work will tell you which fits. Update history - **20 Sep 2026** — **Ownership note: Grammarly is now part of Superhuman.** Grammarly's homepage carries the line and the footer reads "2026 © Superhuman Platform"; the parent renamed itself on 29 October 2025\. Grammarly's plans page now describes Enterprise as "available through Superhuman Go". **No price moved: Pro is still US$12/month billed annually and US$30/month month to month**, confirmed from the plans data served to an Australian IP (Monthly US$30, Quarterly US$60, Annual US$144).
