Whether you write blog posts, client copy, academic essays, or emails for work — Chrome can become your best writing environment with the right extensions. The wrong ones will slow you down, distract you, and produce mediocre output.
This list covers the extensions I actually use for writing, with specific notes on what type of writer gets the most value from each one.
Quick Pick: If you only install two writing extensions, make them Grammarly (real-time grammar and clarity across every text field) and Readwise Reader (save research and articles to actually read them). Everything else on this list is situational.
Grammar & Style
01Grammarly
Real-time writing correction everywhere in Chrome
Still the standard. Grammarly’s Chrome extension works in every text field — Google Docs, Notion, WordPress, Gmail, LinkedIn, Slack — and catches spelling, grammar, punctuation, and clarity issues in real time. The free tier handles the essentials. Premium adds tone adjustment, clarity rewrites, and plagiarism checking.
The newer GrammarlyGO AI features let you generate and rewrite text directly in any field, which is useful for drafting emails and short-form copy quickly. For long-form articles, the standalone editor is better — but for everything else in Chrome, the extension is indispensable.
Free tier: Yes
Premium: ~$12/mo
Best for: Everyone who writes
02LanguageTool
Best free Grammarly alternative — supports 30+ languages
If you write in multiple languages or want a privacy-focused alternative to Grammarly, LanguageTool is the pick. It’s open source, supports over 30 languages including Spanish, French, German, and Portuguese, and the free tier is more generous than Grammarly’s. Style suggestions are slightly less sophisticated, but for multilingual writers it’s the clear choice.
Free tier: Very good
30+ languages
Privacy-friendly
AI Writing Assistance
03Claude / ChatGPT Extension
AI rewriting and drafting on any page
The official Claude and ChatGPT browser extensions let you highlight any text on any page and instantly ask AI to rewrite it, summarise it, continue it, or change its tone. For bloggers and freelancers, this is transformative — you can draft a quick email reply, rewrite a clunky paragraph, or get unstuck on a blog intro without leaving your current tab.
Claude’s extension tends to produce more natural prose; ChatGPT’s has better tool integrations. Both have free tiers worth trying.
Free tier: Both
Works on any text field
Best for: Bloggers, freelancers
Research & Note-Taking
04Readwise Reader
Save everything you need to read — and actually read it
Research is half of writing. Readwise Reader’s Chrome extension saves any article, newsletter, PDF, or Twitter thread to your reading queue in two clicks. Inside the app, you highlight key passages that sync automatically to Notion, Obsidian, Roam, or your preferred note-taking system.
For bloggers and students who do a lot of research before writing, this is the tool that turns “50 open tabs I’ll read later” into an organised, searchable research library.
60-day free trial
$7.99/mo after
Syncs highlights to Notion
05Roam Research or Notion Web Clipper
Save web content directly to your notes
If your writing workflow is based in Notion or Roam Research, their official Chrome extensions let you clip any webpage — full article, simplified view, or screenshot — directly into your workspace. Notion’s clipper also extracts structured data from product pages and articles. Useful if you’re building a content database or research repository.
Both free
Clips to your workspace
Best for: Note-takers
Focus & Distraction Blocking
06Cold Turkey Blocker
Nuclear option for distraction-free writing sessions
Writers face a specific distraction problem: the research phase bleeds into social media, which bleeds into an hour of news. Cold Turkey Blocker creates a hard wall around your writing sessions — blocked sites can’t be unblocked until the timer runs out, even if you uninstall the extension (it uses a system-level block). The “Writer Mode” is particularly useful: it can lock Chrome to one tab or one document until you hit a word count goal.
Free version: Good
Pro: $39 one-time
Unbypassable blocks
07Mercury Reader / Reader Mode
Strip pages down to text for distraction-free reading
When researching, the cluttered sidebars, ads, and related-article recommendations on most websites are constant temptations to click away. Mercury Reader (or Chrome’s built-in Reader Mode, enabled in flags) strips any article to clean, readable text. Essential for writers who need to read sources without getting sucked into rabbit holes.
Free
Clean reading view
Removes all distractions
Productivity & Workflow
08WordCounter Plus
Instantly count words on any webpage
Simple but endlessly useful. Select any text on any webpage and WordCounter Plus shows you the word and character count instantly. Invaluable for checking competitor article lengths, measuring your own drafts in Google Docs, and ensuring social media posts hit character limits. Free, tiny, no permissions creep.
Free
Select text → count
~1MB memory
09Scribe
Auto-generate step-by-step guides from your screen
For bloggers and content writers who do how-to tutorials, Scribe is a genuine time-saver. You click “start recording,” do the process you want to document on screen, and Scribe auto-generates a step-by-step guide with annotated screenshots. What takes 45 minutes to write manually takes 5 minutes with Scribe. The free tier allows a limited number of documents per month.
Free tier: Limited docs
Pro: $29/mo
Best for: Tutorial bloggers
10Hemingway Editor (Web)
Paste and clean up your prose before publishing
Technically not a Chrome extension — but hemingwayapp.com is worth bookmarking and pinning. Paste your draft and it highlights sentences that are too long, adverbs you should cut, passive voice, and readability grade. The goal isn’t to write like Hemingway — it’s to make your writing cleaner and more readable. Takes 2 minutes to run any piece through before publishing.
Free web version
Desktop app: $19.99 one-time
Best pre-publish check
