If you write copy for a living, Chrome extensions can save you hours each week. The best ones check grammar, analyze competitor copy, improve readability, manage research, and help you write faster without losing quality. This article covers 10 extensions that copywriters genuinely use and recommend.
Why Copywriters Need the Right Chrome Extensions
Writing good copy takes focus. But you also need to research competitors, check facts, verify grammar, and manage multiple drafts. Doing all this manually drains your mental energy.
Chrome extensions sit in your browser. They work while you write. No context switching. No leaving your document.
The right extensions handle routine tasks. This frees your brain for the hard work: strategy, angles, and persuasion.
What Makes a Good Chrome Extension for Copywriters
Before we cover the specific tools, understand what separates useful extensions from noise:
Speed matters. If an extension slows your browser or takes three clicks to use, you won’t use it.
It solves one problem well. Extensions that try to do everything usually do nothing great.
It integrates with where you already work. Gmail, Google Docs, WordPress, or your CMS. Tools that work inside your existing workflow get used.
It doesn’t distract. Pop-ups and notifications break focus. The best tools work quietly.
Keep these standards in mind as you evaluate each extension below.
The 10 Best Chrome Extensions for Copywriters
1. Grammarly
What it does: Checks grammar, spelling, punctuation, and tone across any website.

How to use it:
You install the extension. It runs automatically on Gmail, Google Docs, WordPress editors, and most text fields. You see suggestions in real time. Click to accept or ignore each one.
Real example: You write “The product helps improve customer retention.” Grammarly flags this as passive voice and suggests “The product improves customer retention.” Subtle. Powerful.

2. SEMrush SEO Writing Assistant

How to use it:
Open the extension while writing in Google Docs or your CMS. Enter your target keyword. The tool checks keyword density, readability, tone, and originality. It flags what needs work.
Real example: You’re writing a landing page for “best project management software.” The extension tells you that you need more keyword variations, your sentences are too complex, and your originality score is low (you might be copying competitor language).

Paste your text into the Hemingway Editor. It colors code issues. Yellow for complex sentences. Red for very hard sentences. Adverbs flagged. Passive voice highlighted.
Real example: Your sales email reads: “It is believed by many customers that our solution provides significant value through comprehensive feature sets.” Hemingway flags this as “very hard to read.” You rewrite: “Customers tell us our solution delivers real value through powerful features.” Clarity jumps.

How to Choose the Right Extensions for Your Workflow
Not every copywriter needs every extension.
Ask yourself these questions:
Do I write for search rankings? Get SEMrush and Keywords Everywhere.
Do I manage multiple accounts or client sites? Get LastPass and Loom.
Do I need to research prospects quickly? Get Hunter and MozBar.
Am I worried about clarity or plagiarism? Get Hemingway and Copyscape.
Install the ones that solve your actual problems. Start with Grammarly. Add others as you find gaps.
How These Extensions Work Together
The best copywriters use multiple extensions as a system.
Here’s a real workflow:
- Research phase: Hunter finds prospect contacts. MozBar checks their authority. Save to Pocket keeps inspiration organized.
- Writing phase: Hemingway keeps sentences clear. Grammarly catches errors. Keywords Everywhere guides optimization.
- Submission phase: Copyscape confirms originality. SEMrush Writing Assistant validates SEO. Loom creates video feedback for clients.
Each extension handles one job. Together, they cover the entire copywriting process.
Extensions to Avoid
Some popular extensions waste your time:
Social media blockers sound helpful. They’re not. The real issue isn’t the tool. It’s discipline.
Grammar extensions that aren’t Grammarly usually miss things and create false positives. Stick with established tools.
Keyword research extensions that show keyword data inside Google results often have inaccurate data. Use dedicated tools instead.
Focus on the 10 listed above. They work. They’re proven.
Installation and Setup Best Practices
Install properly:
Go to the Chrome Web Store. Search for the extension by name. Click “Add to Chrome.” Allow permissions it requests.
Organize your toolbar:
Once installed, right-click the icon. Pin it to your toolbar. Unpin extensions you don’t use constantly. A cluttered toolbar slows you down.
Sync across devices:
Use a Chrome account. Extensions sync across your devices. Your setup stays consistent.
Check permissions:
When installing, review what data each extension accesses. Grammarly needs text access. That’s normal. If an obscure extension needs access to all data, skip it.
Update regularly:
Chrome updates extensions automatically. Check occasionally that you’re running current versions. Outdated extensions sometimes break.

Common Mistakes Copywriters Make With Extensions
Mistake 1: Too many extensions.
Each extension uses resources. 20 extensions slow your browser. Start with three. Add more as you need them.
Mistake 2: Trusting extensions completely.
Grammarly makes mistakes. SEMrush suggestions aren’t always right. Hemingway flags things you want to keep. You’re the final editor. Always.
Mistake 3: Not learning the tools.
Installing an extension isn’t enough. Spend 15 minutes learning its features. Read the guide. Watch a demo video. Most copywriters use 20% of features available.
Mistake 4: Using free versions only.
Some free versions are sufficient (Hemingway, Pocket). Others limit you too much (SEMrush, Copyscape). Invest in the right tools.
Mistake 5: Not reviewing options periodically.
Tools improve. New extensions launch. Review your toolkit quarterly. Something better might exist now.

When to Replace or Upgrade Extensions
Extensions sometimes stop working. Or better alternatives launch.
Replace an extension when:
It hasn’t updated in six months.
It slows your browser noticeably.
A competitor tool has significantly better features.
You realize you never actually use it.
Upgrade to premium when:
The free version limits what you need.
Premium saves more time than it costs.
You’re using the tool daily.
Free version gives false negatives.
For example: Free Copyscape gets expensive at $5 per check if you run 20 checks monthly. Premium becomes worth it.
The Real Impact on Your Copywriting
These extensions won’t make you a great copywriter. Only practice does that.
But they will make you a more efficient copywriter.
They handle the mechanical work. Grammar. Format. Duplication. Research. Password management.
This frees your brain for the work that actually matters: strategy, insight, persuasion, angles.
A great copywriter with these tools beats a great copywriter without them. Every time.

FAQs
Is Grammarly enough, or do I need other grammar extensions?
Grammarly is sufficient for grammar alone. But copywriting needs more than grammar. You also need clarity (Hemingway), SEO optimization (SEMrush), and originality (Copyscape). So Grammarly is a foundation, not a complete solution. Use it with other tools.
How much do these extensions cost in total?
If you use premium versions of all 10 extensions, approximately $500-800 yearly. But you won’t use all 10. Most copywriters use 4-6 tools, which costs $100-300 yearly. Start with free versions. Upgrade specific tools as your business grows.
Can I use these extensions on mobile or just desktop?
Chrome extensions work on desktop Chrome only. For mobile work, you’ll need different tools. Some like Grammarly have mobile apps. Loom has mobile. Keywords Everywhere and others are desktop only. Mobile is a different workflow.
Do these extensions slow my browser?
Multiple extensions can slow your browser slightly. Each extension uses some RAM. But the 10 listed here are all lightweight compared to earlier versions. Install them. Monitor your browser speed. If it becomes noticeably slower, uninstall the ones you use least.
Which extensions would be best for a complete beginner copywriter?
