Most Popular🗒️ What is Grammarly?
AI writing assistant that checks grammar, style, tone, and clarity in real time across browsers, docs, and email.
Grammarly checks grammar, spelling, tone, and clarity in real time across browsers, Microsoft Office, Google Docs, and most places you type online. Beyond corrections, it offers Authorship, a feature that tracks and discloses how a document was actually written (typed, pasted, or AI-generated) -- useful for students and professionals who need to demonstrate original work -- plus a set of specialized AI writing agents for tasks like proofreading, tone adjustment, and paraphrasing.
Grammarly is particularly strong at catches grammar, tone, and clarity issues, works across 500K+ apps, and plagiarism checker included, making it a popular choice for professional email writing and academic paper editing. One thing to keep in mind: advanced features require Premium.

🔀 Best Grammarly alternatives
QuillBot
A stronger dedicated paraphrasing tool if rewriting existing text is your main use case.
Wordtune
A lighter-weight rewriting tool worth comparing for quick tone and phrasing adjustments.
Jenni AI
Better suited to academic writing that needs citation support alongside editing.
Copy.ai
A better fit if you need to generate new marketing copy from scratch, not just edit existing text.
🏆 Is Grammarly worth it?
Grammarly earns its 4.7 by being the most reliable, lowest-friction proofreading layer available -- it works everywhere you already write, catches real errors, and Authorship adds a genuinely useful paper trail for anyone who needs to prove a document wasn't AI-written. It's not the right tool if you need to generate substantial new content from a brief -- Grammarly edits and improves existing text rather than drafting from scratch, so a generation-focused tool like Jasper or Copy.ai fits that job better, and its AI detection (like all AI detectors) shouldn't be treated as definitive proof either way.
❓ Frequently Asked Questions
Is Grammarly free to use?
Yes, the free plan covers basic grammar and spelling checks, the browser extension, and the Microsoft Office add-in. Advanced style rewrites, the plagiarism checker, and Authorship reports require a paid plan.
How much does Grammarly Premium cost?
Pricing has shifted between annual and monthly billing tiers -- check grammarly.com/premium for the current rate, as annual billing is typically significantly cheaper per month than paying monthly.
What is Grammarly Authorship?
Authorship tracks how a document was written -- typed, pasted, or AI-generated -- and produces a report you can share to demonstrate the writing process, which is useful for students and professionals who need to disclose or prove original authorship.
Can Grammarly detect AI-generated text reliably?
It can flag likely AI-generated passages, and Authorship reports add process-level evidence, but like all AI detectors it isn't 100% accurate and shouldn't be used as the sole basis for high-stakes decisions.
Does Grammarly work in Google Docs and Microsoft Word?
Yes, Grammarly has dedicated integrations for both, plus a browser extension that works in most web-based text fields including email and Slack.
Is Grammarly only for grammar and spelling?
No -- beyond corrections, it offers tone detection, full-sentence clarity rewrites, a plagiarism checker, and a set of specialized AI agents for tasks like paraphrasing and proofreading long documents.
How does Grammarly compare to QuillBot?
Grammarly is stronger as an always-on proofreading and tone layer across everywhere you write; QuillBot is more focused specifically on paraphrasing and rewriting existing passages.
