14 Chrome Extensions for Bloggers, Sorted by Task

The best Chrome extensions for bloggers cover five jobs: writing (Grammarly, ProWritingAid, LanguageTool), research (TubeOnAI, Hypothesis, Evernote Web Clipper, Notion Web Clipper), SEO (SEOquake, Keywords Everywhere), images (TinyPNG) and focus, planning and promotion (Momentum, OneTab, Trello, Buffer). You don’t need all fourteen. Pick one per job you actually do in the browser.

Every extension below was checked in the Chrome Web Store in October 2026. That matters more than it used to: Chrome turned off older Manifest V2 extensions for all users in July 2025 and removed the remaining ones from the store on August 31, 2026, according to Google’s Manifest V2 timeline. Many older “best extensions” lists still recommend tools you can no longer install. For general-purpose picks beyond blogging, see our list of free Chrome extensions.

All 14 Extensions at a Glance

Writing and Editing

1. Grammarly

Grammarly checks grammar, spelling, clarity and tone in real time as you type in Gmail, Google Docs, LinkedIn and, according to its store listing, 500,000+ other sites. It’s the default choice for catching typos and awkward phrasing before you hit publish. There’s a free plan, and the paid Pro plan adds full-sentence rewrites and tone adjustments.

Best for: a fast final check on every post. Keep in mind: it polishes sentences. It won’t fix a weak structure or argument. Compare it with other AI writing tools if you want more rewriting help.

2. ProWritingAid

ProWritingAid goes deeper than a grammar checker. Alongside grammar, spelling and paraphrasing, it offers 25+ writing reports covering things like overused words, sentence length variety and readability. It works in Google Docs, Notion and other writing apps, and has a free plan.

Best for: long-form bloggers who want editor-style feedback on their habits. Keep in mind: the volume of suggestions can be a lot on a first draft. Run it during editing, not while you write.

3. LanguageTool

LanguageTool is a grammar, style and paraphrasing checker that supports more than 25 languages and distinguishes between American and British English. The basic extension works without registering.

Best for: bloggers who write in more than one language, or who want a lighter alternative to Grammarly. Keep in mind: the free version gives fewer suggestions, and like any checker it flags some false positives.

Research and Saving Sources

4. TubeOnAI

TubeOnAI is our own tool, so weigh this pick accordingly. Its Chrome extension summarizes YouTube videos, web pages and PDFs. That’s useful when your research means a long interview, a conference talk or a dense report. In the web app you can also summarize podcasts and Google Docs, ask follow-up questions about a summary, and repurpose content into a blog post draft, X thread or newsletter, for example turning a podcast episode into a blog post. The free Starter plan includes 400 credits.

Best for: getting through video, audio and long documents faster during research. Keep in mind: an AI summary is a starting point. Check quotes and facts against the original before you publish.

5. Hypothesis

Hypothesis lets you highlight, tag and annotate web pages, PDFs and EPUBs. You can use it for personal notes or for collaborative discussions on the same source, which makes it handy for co-authors or a team of writers working from shared material.

Best for: annotating sources you’ll quote or argue with. Keep in mind: group discussions are only useful if your collaborators use it too.

6. Evernote Web Clipper

Evernote Web Clipper saves articles, full pages, PDFs, bookmarks and screenshots into your Evernote notebooks, and lets you annotate screenshots with highlights and text. It turns a mess of bookmarks and copy-pasted notes into one searchable research library.

Best for: bloggers who already use Evernote for notes. Keep in mind: it requires an Evernote account. A simple tagging system, such as topic tags plus status tags like “to read” or “cited”, stops the clipping from turning into hoarding.

7. Notion Web Clipper

If you plan content in Notion, its official Web Clipper saves any web page to your Notion workspace, and you choose exactly where it goes. You can drop sources straight into the page or database where you track post ideas and drafts.

Best for: bloggers who run their editorial calendar in Notion. Keep in mind: Notion’s flexibility is also its trap. Keep your workspace simple so setting it up doesn’t replace writing. It’s also useful to organize research material for bigger pieces.

SEO and Keyword Research

8. SEOquake

SEOquake, from Semrush, is a free on-page SEO checker. It audits the page you’re on (robots directives, hreflang, sitemap, image alt text, structured data), analyzes links and keyword density, and adds an overlay with Semrush metrics under each Google result.

Best for: quick checks on your own posts and a look at what competing pages do. Keep in mind: the SERP overlay shows a lot of data at once and can slow searches. Turn it off when you don’t need it.

9. Keywords Everywhere

Keywords Everywhere is a freemium extension that shows keyword data alongside Google, YouTube, Amazon and other sites. The free version includes traffic estimates for URLs and domains. The paid version adds search volume, CPC and competition data.

Best for: checking demand for a topic without leaving the search results. Keep in mind: the most useful data (search volume) needs paid credits.

Worth pairing with: Answer The Public. It’s a website, not a Chrome extension, so it isn’t counted in this list. It maps the questions people search around a keyword, which is a quick source of post ideas and FAQ sections.

Images

10. TinyPNG

Large images are one of the most common reasons a blog post loads slowly. Tinify, the company behind TinyPNG, has an official extension that compresses and converts AVIF, WebP, PNG and JPEG images in the browser.

Best for: shrinking screenshots and photos before upload. Keep in mind: the official extension is new and has few users so far. Make sure you install the listing offered by Tinify, not a look-alike.

Focus, Planning and Promotion

11. Momentum

Momentum replaces Chrome’s new-tab page with a calm dashboard: a background image, a daily focus you set yourself, and a to-do list. It’s a gentle nudge back to the post you’re meant to be writing every time you open a tab. A paid Plus tier adds features such as unlimited focus mode.

Best for: writers who drift to social media when they open a new tab. Keep in mind: it’s a reminder, not a task manager.

12. OneTab

OneTab collapses all your open tabs into a single list, which it says can save up to 95% of memory. You can restore tabs one at a time or all at once, or share a list as a web page. It’s useful at the end of a research session, and as a quick reading list.

Best for: research-heavy posts with dozens of tabs open. Keep in mind: it’s easy to send tabs to OneTab and never look at them again. Prune the list regularly.

13. Trello

Trello’s official Chrome extension saves any web page, or part of one, as a card on your board. If you run your content pipeline in Trello (ideas → drafting → editing → published), it’s a quick way to capture post ideas and sources as you browse.

Best for: visual planners and blogs with guest writers. Keep in mind: boards get cluttered as a blog grows. Archive finished cards and keep Trello for high-level planning.

14. Buffer

Buffer’s extension lets you share the page you’re on, or schedule a post about it, to your connected social accounts without opening the Buffer dashboard. It’s the quickest way to promote a new post the moment it goes live.

Best for: bloggers who promote their own posts on social media. Keep in mind: you need a Buffer account with your social profiles connected.

How to Keep Extensions from Slowing Chrome Down

• Install for a job, not “just in case.” One grammar checker is enough. Running two produces conflicting underlines.
• Review and remove unused extensions every few months at chrome://extensions. Toggle off the ones you only need occasionally, like SEO overlays.
• Check the publisher before installing, especially for popular tool names that attract copycat listings.
• Prefer recently updated extensions. If a listing hasn’t been updated in years, it may stop working with future Chrome versions.

AI tools are changing what a blogger’s browser setup looks like, but the principle hasn’t changed: use extensions to remove friction from writing, not to replace it. If you summarize sources with AI, make sure you summarize them without plagiarizing.

Frequently Asked Questions

Are there free Chrome extensions for bloggers?

Yes. Grammarly, ProWritingAid and TubeOnAI have free plans, and SEOquake is a free extension. OneTab and Momentum are free to install, with Momentum offering a paid Plus tier. Keywords Everywhere has a free version, though search-volume data needs paid credits.

Which Chrome extensions help with blog SEO?

SEOquake for on-page audits and competitor metrics, and Keywords Everywhere for keyword data in search results. Answer The Public is a useful companion for question research, but it’s a website rather than an extension.

Is there a Chrome extension for compressing blog images?

Yes. TinyPNG’s official extension, published by Tinify, compresses and converts AVIF, WebP, PNG and JPEG images in the browser before you upload them.

Can Chrome extensions help with social media promotion for my blog?

Yes. Buffer’s extension lets you share or schedule a post about the page you’re on to your connected social accounts. Hootsuite’s old Hootlet extension is no longer available in the Chrome Web Store, so Hootsuite users schedule from the Hootsuite dashboard instead.

Why did some of my old blogging extensions stop working?

Chrome has completed its move to Manifest V3. Manifest V2 extensions were disabled for all users in July 2025, and the remaining ones were removed from the Chrome Web Store on August 31, 2026. If an extension stopped working, look for an updated version from the same developer or a replacement.
