- ProWritingAid, LanguageTool, built-in AI assistants
Grammarly's superpower was never the grammar engine — it's the ubiquity. It checks your writing in Gmail, Google Docs, LinkedIn, Slack, your CMS, everywhere, without you switching apps. Years of AI features have been layered on top, and the result is the best passive writing quality tool available, even as chatbots eat parts of its lunch.
Pros
- Works everywhere you type — browser, desktop, mobile
- Clarity and conciseness suggestions genuinely improve writing
- Tone detection catches emails that read wrong
- AI drafting and rewriting built in
- Strong free tier for basics
Cons
- Premium price adds up vs free alternatives
- Suggestions can flatten a distinctive writing voice
- Full AI assistants can do deeper rewrites when asked
What you get free vs Premium
Free covers real grammar, spelling and punctuation — better than most people expect. Premium (around $12/month billed annually) adds the good stuff: clarity rewrites, conciseness suggestions, tone adjustment, vocabulary improvements and plagiarism detection. The clarity suggestions are where the money is; they consistently tighten flabby sentences.
Grammarly in the age of ChatGPT
Chatbots can rewrite anything you paste into them — but that's the point: you have to paste. Grammarly's value is being passively present in every text field, catching the typo in the email you were about to send to a client. As a safety net rather than a writing partner, nothing else matches its coverage.
Who should pay
If writing quality affects your income — freelancers, job seekers, marketers, executives, non-native English speakers — Premium earns its price. If you mostly write casual messages, free is plenty.
Scorecard
Overall: 8.4/10. Still the best always-on writing net. Keep your voice — accept its fixes, not all its style opinions.
Frequently asked questions
Is Grammarly Premium worth it?
If your writing is professionally visible, yes — clarity and tone features go well beyond free. Casual writers can stay free.
Does Grammarly work in Google Docs and Gmail?
Yes — browser extensions and desktop apps cover virtually everywhere you type.
Is Grammarly better than ChatGPT for editing?
For passive, always-on checking, yes. For deep restructuring of a document, a full AI assistant does more when explicitly asked.
