About Grammarly

Grammarly is the AI writing assistant used by more than 30 million people and 70,000 teams worldwide. It runs as a browser extension, desktop app, and keyboard on mobile - checking your writing across Gmail, Google Docs, Slack, LinkedIn, Word, and virtually every other platform where you type. The core product is a real-time grammar and spell checker, but Grammarly has evolved well beyond that. Its AI now rewrites entire sentences for clarity, suggests vocabulary upgrades, adjusts the tone of your writing to match a given context, and flags when something reads as too formal, too casual, or potentially offensive to a specific audience. The business plan extends this with a brand tone feature - so everyone on a team writes with a consistent voice. Grammarly Business includes a plagiarism detector, writing analytics across the team, and style guide enforcement. For organisations producing a lot of external content - proposals, support emails, marketing copy, legal documents - the consistency and quality lift across the team is meaningful. The free plan covers basic grammar and spelling corrections and is useful on its own. Grammarly Premium at $12 per month (billed annually) unlocks the full rewriting, tone detection, and style suggestions. Grammarly Business is priced per seat starting at $15 per member per month, with volume discounts for larger teams. Grammarly is best suited to professionals who write in English and want to ship polished, error-free text faster - without a dedicated editor reviewing their work.

Compared with Grammarly (5)

  • Grammarly vs Jasper โ†’tie

    Grammarly and Jasper are both AI writing tools, but they solve different problems.

Jasper wins for marketing teams who need to produce high-volume content at speed.

  • Grammarly vs Quillbot โ†’tie

    Grammarly and QuillBot are the two most widely used AI writing improvement tools, but they solve different problems. Grammarly is primarily an editing assistant - it catches grammar, spelling, clarity, and tone issues in real time across every app you write in. QuillBot is primarily a rewriting and paraphrasing tool - it transforms existing text into new versions, which makes it more useful for repurposing content and avoiding repetition. Many writers use both: Grammarly for real-time editing while writing, QuillBot for reworking finished drafts.

  • Grammarly vs Wordtune โ†’tie

    Grammarly leads on grammar and correctness checking; Wordtune leads on rewriting and improving existing prose. They solve different problems - Grammarly catches errors, Wordtune improves style.

  • Grammarly vs Writesonic โ†’Grammarly wins

    Grammarly and Writesonic serve adjacent but distinct writing needs. Grammarly is fundamentally an editing and proofreading tool - it improves content you have already written, catching grammar issues, tone mismatches, clarity problems, and now offering AI rewrites within its editing interface. Writesonic is a content generation tool - it creates first drafts from prompts, generates SEO-optimised blog posts, rewrites for different audiences, and outputs marketing copy at scale. The comparison is less head-to-head and more sequential: many writers use Writesonic to generate a draft and Grammarly to edit it. Where they compete directly is in AI writing assistance: Grammarly's generative features are more restrained and editorial; Writesonic's generation is higher volume but requires more editing. For teams that primarily need editing and consistency checking, Grammarly wins. For teams that need volume content generation with SEO optimisation, Writesonic wins.

  • Grammarly vs Originality Ai โ†’tie

    Originality.ai vs Grammarly addresses the same content, at opposite ends of the quality control process. Grammarly improves the writing before publishing: grammar, spelling, clarity, tone, and readability. Originality.ai audits the writing after it is created: AI content detection, plagiarism checking, and readability scoring. The tools are not direct competitors - they serve different quality control functions. Teams using AI writing tools need both: Grammarly to improve the output quality and clarity, Originality.ai to verify the content will not be flagged as AI-generated by publishers or search engines. The overlap is in plagiarism and readability, where both tools offer checks. But for pure AI detection, Originality.ai is the specialist - and for pure writing improvement, Grammarly is the benchmark.
