Proofreading Your Website
Please wait while we check your website for spelling errors, grammar mistakes, and more. This may take a few moments...
Proofread a URL now
Enter any page URL to run a quick spell check in the main app. Use this when you want results right away without installing the extension first.
No payment required
Instant analysis
See issues where they appear
Potential misspellings are highlighted on the page so editors, marketers, and clients can see the problem immediately.
Review suggestions quickly
Open the extension popup to inspect flagged text, review context, and move through fixes without digging through the page.
Made for last-minute QA
Use it before launch, during approvals, or in client review when a full crawl would be overkill.
How to use it right now
- 1 Download the extension files from GitHub and load them into Chrome.
- 2 Open the page you want to review and run a page check from the extension.
- 3 Fix what you find, then switch to the web app when you need broader site coverage.
Built for fast page-level QA
The extension keeps the workflow simple: run a check, review highlighted issues on the page, and use the popup to work through suggested fixes. It is a strong fit for marketers, editors, and developers who need fast feedback inside the browser.
When the job shifts from "check this page" to "review this entire site," the browser extension hands off cleanly to the main Site Spell Checker product.
Extension vs full website scan
Use the extension for quick checks inside Chrome. Use the web app when you need broader coverage and a report you can work from later.

Frequently Asked Questions
Is the extension live in the Chrome Web Store yet?
Not yet. For now, installation runs through the GitHub repo and Chrome's "Load unpacked" flow.
What does the extension actually do?
It checks the page currently open in Chrome, highlights likely spelling issues on the page, and shows suggestions in the extension popup.
How is this different from the main Site Spell Checker app?
The extension is for quick page-level review while you browse. The main app is for scanning whole sites, reviewing larger batches of issues, and sharing results.
Can I use it before the Web Store listing is live?
Yes. The GitHub repo includes the files needed to install the extension locally in Chrome.
