Grammarly
Grammarly is AI writing assistance that proofreads, rewrites and adjusts tone inside the apps you already type in.
Grammarly's advantage is deployment, not depth. It already sits in the browser, the Office ribbon and the Zendesk reply box, so rolling it out to a team costs almost nothing — which is why 50,000 organizations pay for it. Pro at $12 per member per month billed annually ($30 month-to-month) is fair once you want full-sentence rewrites, plagiarism and AI-text detection, and more than 100 prompts a month. The AI-native Docs workspace with agents like AI Grader and Citation Finder is genuinely new, not a repackage. Go to ProWritingAid if your work needs line-level style critique, Zotero or EndNote for real reference management, or LanguageTool if you need language coverage Grammarly doesn't

Skip Grammarly if you need line-level style critique, real reference management, or offline operation — ProWritingAid, Zotero or EndNote cover those better, and Grammarly needs a cloud connection.
Going past 2,000 AI prompts per member per month on Pro means upgrading to Enterprise, since prompts do not roll over between months
Pro at $12 per member per month billed annually ($30 month-to-month) is the cheapest serious writing assistant for a team already inside Microsoft 365 or Google Workspace, and it undercuts ProWritingAid Premium on a per-seat basis. Free covers individual proofreading well enough that solo writers may not need to pay. Enterprise is the real step up: only there do you get BYOK, DLP, SAML SSO, SCIM and unlimited prompts, so a 200-person regulated company is effectively buying the top tier, not Pro.

About Grammarly
Grammarly is an AI writing assistant that sits inside the places you already write: browser extensions for Chrome, Safari, Firefox and Edge, Windows and Mac desktop apps, iPhone, iPad and Android keyboards, plus Microsoft Office, Google Docs and Zendesk. You type, it flags, you accept or ignore. The vendor cites 40 million people and 50,000 organizations. The free tier covers mistake-free writing, tone detection and 100 AI prompts a month. Pro runs $12 per member per month billed annually ($30 billed month-to-month) and adds one-click full-sentence rewrites, tone adjustment, fluent English, inclusive language, citation consistency, plagiarism and AI-text detection, and 2,000 prompts per member monthly. Enterprise is contact-sales only and layers on confidential mode, BYOK encryption, data loss prevention, SAML SSO, SCIM, an audit logs API, cost center visibility and unlimited prompts, now delivered alongside Superhuman Go. The product has moved well past grammar. Recent releases added speech-to-text dictation into any supported app, Grammarly Docs as a collaborative AI-native workspace with context-aware agents including AI Grader, Citation Finder and Reader Reactions, multilingual writing and rewrites in Spanish, French, Portuguese, German and Italian with translation across 19 languages, and Grammarly Authorship inside Blackboard for AI-use transparency in academic work. Three buyers get real value: individual professionals polishing daily email and reports, marketing and sales teams enforcing brand voice through style guides, brand tones and snippets, and enterprises standardizing writing across departments. The frictionless upside is also the ceiling — this is a corrector and rewriter, not a reference manager or a line-editing studio.
Behind the Verdict
Grammarly's real moat is not the language model — it is 15 years of distribution. The extension is already installed, the Office add-in is already trusted by IT, and the Zendesk sidebar already loads in your support queue. That is why a rollout to 500 people takes a week rather than a quarter, and why the 50,000-organization figure holds up. If you are buying writing help for a team that already types in Google Workspace or Microsoft 365, the switching cost of evaluating anything else is the actual competitor. The feature set has widened considerably past spellcheck. Pro adds one-click full-sentence and paragraph rewrites, tone adjustment, fluent-English rewriting, inclusive-language suggestions, citation consistency, plagiarism detection and an AI Detector the vendor says ranked first in an independent quality evaluation. Prompt allowances are the sharp edge: 100 a month on Free, 2,000 per member per month on Pro, unlimited on Enterprise. A heavy user who drafts with AI daily will feel 2,000 arrive faster than expected. Grammarly Docs is the most interesting recent move — an AI-native document editor rather than a layer on someone else's canvas. Its agents (Proofreader, Paraphraser, Humanizer, AI Detector, Plagiarism Checker, Reader Reactions, Citation Finder, AI Grader) each target a stage of the writing process. Reader Reactions, which previews how an audience is likely to read a draft, is a genuinely uncommon capability. Citation Finder is useful but shallow — it is not a reference manager and will not replace Zotero or EndNote for anyone writing a dissertation or a systematic review. Where it falls short: style analysis is coarse compared with ProWritingAid's line-level reports, offline and air-gapped work is not viable, and the supported language set — English plus Spanish, French, Portuguese, German and Italian, with translation across 19 languages — is narrower than LanguageTool's. Enterprises get the strongest tier here: confidential mode, BYOK, DLP, SAML SSO, SCIM, an audit logs API and cost center visibility are exactly the controls a security review asks for, and they are Enterprise-only, not Pro. For an individual who wants sentence-level help without thinking about it, Pro is a straightforward buy. For a team that needs style depth or reference management, Grammarly is a complement, not a replacement.

Real-world workflow fit
Concrete scenarios for the personas Grammarly actually fits — and what changes day-one when you adopt it.
Installs the Chrome extension and desktop app on day one, writes proposals and replies as usual, and accepts sentence rewrites and tone suggestions inline without leaving Gmail or Outlook
Outcome: Faster replies with fewer follow-up clarification threads; Free covers proofreading, and Pro at $12 per member per month billed annually unlocks full-sentence rewrites once the 100-prompt cap starts biting
Sets up a style guide, brand tones and shared snippets, then rolls Pro seats out to writers so every draft picks up the same terminology and tone rules
Outcome: Consistent external copy without a review bottleneck; the analytics dashboard tracks adoption, but unlimited style guides and brand tones require Enterprise
Deploys the Zendesk integration plus browser extensions so agents get on-brand rewrite suggestions inside the reply box, with tone adjusted for frustrated customers
Outcome: Shorter handle times and more consistent replies; note that the compliance-grade controls — DLP, confidential mode, audit logs API — are Enterprise-only, so start that conversation early if security will ask
Use Cases
- Polishing professional emails for clarity and tone before sending
- Checking spelling and grammar in Google Docs before submission
- Drafting social media and marketing copy with a consistent brand voice
- Detecting accidental plagiarism and AI-generated text in academic papers
- Adjusting tone from formal to friendly in customer support replies from Zendesk
- Rewriting paragraphs for clarity in multilingual communications
- Dictating a first draft by voice into whichever app you already write in
- Previewing with Reader Reactions how a sales pitch will land before you send it
Limitations
- Grammarly offers Free ($0), Pro at $12 per member per month billed annually ($30 when billed month-to-month) and Enterprise via contact sales.
- Pro adds full-sentence rewrites, tone adjustment, plagiarism and AI-generated text detection, and 2,000 AI prompts versus 100 on Free.
- It works across browser, desktop, mobile and a Docs writing space.
- Security controls that matter to larger buyers — SAML SSO, SCIM, audit logs API, confidential mode, data loss prevention and BYOK encryption — are Enterprise-only, not Pro.
- Prompt allowances are monthly and reset, not banked.
- The sources do not disclose the underlying AI models or any token limits, and style analysis is coarser than ProWritingAid's line-level reports.

$12/member/mo billed annually ($30 billed monthly)
Ideal for
Professional or small team writing daily email, docs and support replies who want rewrites and plagiarism detection

Larger organizations that need centralized administration, security review sign-off and unlimited AI use across departments

Where the pricing makes sense
The company stage and team size where Grammarly's pricing actually pencils out — and where peers do it cheaper.
Pro at $12 per member per month billed annually ($30 month-to-month) is the cheapest serious writing assistant for a team already inside Microsoft 365 or Google Workspace, and it undercuts ProWritingAid Premium on a per-seat basis. Free covers individual proofreading well enough that solo writers may not need to pay. Enterprise is the real step up: only there do you get BYOK, DLP, SAML SSO, SCIM and unlimited prompts, so a 200-person regulated company is effectively buying the top tier, not Pro.
Setup time & first value
How long it actually takes to get something useful out of Grammarly — broken out by persona, not the marketing-page minute.
Individual: minutes — install the browser extension or desktop app, sign in, and suggestions appear in whatever you already type in. Team on Pro: an afternoon to create the workspace, invite members, and configure a style guide, brand tone and snippets. Enterprise: one to two weeks, mostly spent on SSO, SCIM provisioning and the security review that unlocks confidential mode, DLP and BYOK.
Switching to or from Grammarly
How to bring data in from common predecessors and how to get it back out — written for the switcher, not the buyer.
- →From Microsoft Editor: install the Grammarly extension alongside or instead, keep writing in Word and Outlook, and move team terminology into a shared style guide
- →From ProWritingAid: run both for a month on the same documents, carry your house style rules into Grammarly's style guide, then drop the seat you use less
- →From LanguageTool: map your custom rules into Grammarly style guide entries, accepting that Grammarly's supported language set is narrower
- →From a standalone spellchecker or no tool at all: install the extension and add the Office or Google Docs add-in — there is no document corpus to import
- ↗To ProWritingAid: export or copy your style guide rules into its style settings, then run both on a sample of real documents before cancelling Grammarly seats
- ↗To LanguageTool: recreate style guide entries as custom rules, and re-check any non-English workflows since LanguageTool covers more languages
- ↗To Zotero or EndNote: keep Grammarly for proofing but move citation and reference work out, since Grammarly's citation tools are basic
- ↗To Microsoft Editor: cancel Pro renewal, remove the extensions and add-ins, and move brand terminology into Editor's rewrite settings
