Overview

Founded in 2009 and now part of Superhuman, Grammarly covers more than basic grammar correction. Its tools address proofreading, stylistic refinement, tone checking and assisted drafting in one product. Grammarly says it serves more than 40 million people and 50,000 organizations, making it a credible option for workplaces as well as personal writing.

Content privacy is a clear strength: user content is not sold, used for advertising monetization or used to train third-party models. A SOC 2 Type 2 report covers security, privacy, availability and confidentiality controls. Those assurances matter to organizations deciding whether to put business writing into an online editor.

Key features

Proofreading catches writing problems, while style suggestions help refine wording and tone detection indicates how a passage may sound to readers. Paragraph rewrites and additional tone suggestions support substantial editing rather than isolated corrections. A humanizer and AI detector agents extend the product into drafting review and checking AI-assisted text.

Brand voice controls and team collaboration make the service more suitable for shared editorial standards. Language support covers 24 languages, although the stated interface language support is English. AI usage is governed by monthly quotas: Free includes 100 prompts, while Plus provides 2,000 prompts per member. That difference makes the free tier better for occasional assistance than for sustained AI drafting.

Pricing

Plan	Price and allowance	Best fit
Free	₹0 INR per month; 100 AI prompts monthly	Individuals who need occasional proofreading and limited AI help
Plus	₹392 INR per member per month, billed annually; 2,000 AI prompts per member monthly	Individuals or teams needing substantially more AI use
Plus monthly	₹1,000 per month	Users who prefer monthly billing
Pro	$12.00 per month; 2,000 AI prompts per member monthly	Users seeking the stated Pro allowance
Enterprise	Custom pricing	Larger organizations requiring administrative and security controls

Plus is sold only through local payment methods, which can rule it out for some buyers despite its lower annual monthly equivalent. Enterprise supports unlimited members and adds confidential mode, roles and permissions, data loss prevention, proactive AI across applications, dedicated support, BYOK encryption and cost-center visibility. Support ranges from a help center and basic assistance to priority and dedicated support, so larger deployments get a clearer service path than free users.

Platforms

Grammarly offers a browser extension, desktop app and mobile app. Browser support covers Chrome, Safari, Firefox and Edge. Mobile apps are available for iPhone, iPad and Android, allowing users to carry the same writing workflow across major device types. The combination suits people who move between web applications, computers and phones rather than staying in one editor.

Who it's for

Choose Grammarly if you want proofreading, tone guidance and AI rewriting together, especially when writing spans email, documents and mobile work. The free plan fits light or occasional use. Plus or Pro is more appropriate for regular AI assistance, provided the monthly prompt allowance matches your workload and the payment route works for you. Enterprise is aimed at organizations that need unlimited seats, governance and stronger data controls.

It is less suitable for heavy AI users who would exceed 2,000 prompts per member each month, or for buyers unable to use the local payment methods required for Plus. Writers who need an interface language beyond English may also find the stated language coverage restrictive.

Pros and cons

Pros

Broad editing scope: proofreading, style, tone, rewrites, humanizer and AI detection cover several stages of writing.
Wide access: browser, desktop and iPhone, iPad and Android apps support mixed-device work.
Useful organizational controls: brand voice, collaboration and Enterprise permissions support shared standards.
Privacy commitments: content is not sold, monetized for advertising or used to train third-party models, with SOC 2 Type 2 coverage.

Cons

Prompt caps: Free's 100 monthly prompts and paid plans' 2,000-per-member allowance can constrain intensive AI workflows.
Payment restriction: Plus is available only through local payment methods.
English interface: stated language support is English even though writing support spans 24 languages.

Alternatives

LanguageTool is a freemium choice with extension, iOS, macOS and Windows apps; pick it when those platforms and character-based Basic or Premium limits suit your editing workflow.

DeepL Write is worth choosing when you want a focused writing assistant, including a Write Pro add-on priced at €6.99 monthly on annual billing.

Wordtune fits users who prefer a free daily allowance of rewrites and AI suggestions alongside unlimited spelling and grammar checks.

Paperpal is an alternative for regular research and writing needs, with a Prime plan at $144 per year billed annually.

ProWritingAid suits writers who can work within report-run, rephrase and daily usage limits on its free plan.

QuillBot is another freemium option for users prioritizing paraphrasing, with its free tier limited to 100 words per paraphrase.

Sapling is a fit when API, self-hosted or Windows deployment and detector-oriented limits matter more than Grammarly's broader consumer reach.

Trinka provides another freemium writing option for buyers considering extension, web, macOS, Windows or self-hosted access.

Verdict

Grammarly is a strong choice for individuals and organizations wanting proofreading, tone control and AI writing assistance across nearly any device. Its main advantages are breadth, collaboration features and explicit privacy controls. Look elsewhere if your AI workload will exceed its prompt quotas, if Plus payment methods are unsuitable, or if you require a non-English interface.
