Grammarly

Grammarly checks grammar, spelling, and clarity, and suggests improvements as you write across apps.

What it does

Grammarly is a writing assistant that works inside your browser, documents, and apps. It checks grammar, spelling, and punctuation in real time, and suggests improvements for clarity, tone, and conciseness. Its AI features can rewrite sentences and generate short drafts from prompts.

Best use cases

• Proofreading emails, documents, and messages
• Improving tone and clarity in professional writing
• Catching errors in social posts and applications
• Non-native English speakers polishing their writing
• Quick rewrites and AI-generated short drafts

Who should use it

Basically anyone who writes: students, professionals, job seekers, and non-native English speakers. Especially valuable if your work is judged on how polished your writing looks.

Strengths

• Works everywhere you write — browser, docs, email, apps
• Checks grammar and spelling as you write, including subtle issues
• Free plan covers core grammar and spelling checks
• Offers tone and clarity suggestions for professional writing

Limitations

• Suggestions can be wrong or change your meaning — always review before accepting
• Over-editing can flatten your personal voice if you accept everything
• It's an editor, not a writer — it won't generate full articles for you
• Advanced style suggestions require paid plans — check the official site

Privacy considerations

Grammarly processes the text you type to check it — that means it sees your emails and documents. Review their privacy policy, especially for work content, and check whether your employer restricts such tools.

Commercial-use considerations

Grammarly is a writing assistant, not a content generator, so commercial-use questions are simple: the writing you edit is yours, and using the tool for client emails, reports, and marketing copy is normal usage on every plan. The terms that matter are about data, not ownership — what happens to the text you paste, especially on free versus business plans, and your organization's data processing agreement if you handle client material. We have not reviewed your specific agreement — check Grammarly's current terms of service and privacy terms before routing sensitive client writing through any plan.

Learning curve

Learning curve: minutes — install it and it starts working; customizing suggestions takes a little setup.

Alternatives

ChatGPT — if you need full drafting and rewriting help, not just proofreading.

Claude — if you want an AI assistant for deeper rewriting and long-form editing.

Who should skip Grammarly

• If you need full drafting from a blank page, an AI assistant like ChatGPT or Claude generates complete drafts — Grammarly is for polishing what you wrote.
• If English is your first language and you mostly write casually, the built-in spellcheckers in your apps may already be enough.
• If your employer restricts tools that process text on external servers, check policy before installing — privacy matters more than convenience.

Example workflow with Grammarly

1. Draft the email yourself first in your own words, focusing on what you want to say — don't start with AI text.
2. Let Grammarly flag grammar, punctuation, and clarity issues, and accept or reject each suggestion individually — never accept all blindly.
3. Check the tone suggestions to confirm the email sounds professional but still like you, not a template.
4. Read the final version aloud once yourself to catch any meaning changes the suggestions may have introduced.
