Why Browser Extensions Miss Most Website Typos
Extensions only check the page you're viewing. Your customers see every page. Shouldn't your spell checker?
The fundamental limitation
Browser extensions work on a single page at a time. To check your entire website, you'd need to manually visit every page, remember which ones exist, and hope you don't miss any.
TypoSentry crawls your entire site automatically. It discovers pages, checks them all, and runs again every week—without you lifting a finger.

Why extensions fall short for websites
One page at a time
You have to visit every page manually. Your site has dozens or hundreds of pages. Are you going to check them all?
No page discovery
Extensions don't know what pages exist. That old blog post from 2019? That product page you forgot about? They never get checked.
No ongoing monitoring
Extensions don't run automatically. When a teammate publishes a typo next week, the extension won't catch it unless you happen to visit that page.
Team dependency
Everyone on your team needs the extension installed and configured. If one person doesn't have it, their errors go unnoticed.
Frequently asked questions
Why can't I just use a browser extension to check my site?▼
Browser extensions only check the page you're currently viewing. To check your whole site, you'd need to manually visit every page. TypoSentry crawls automatically and checks all pages in one scan.
What about spell-check extensions that scan entire pages?▼
Even full-page extensions require you to visit each page individually. They don't discover pages automatically, don't run on a schedule, and don't catch errors introduced by other team members.
Do browser extensions work on JavaScript content?▼
It varies. Some extensions struggle with dynamically loaded content. TypoSentry uses a real browser to render pages, catching content from React, Vue, Next.js, and other frameworks.
How many pages can TypoSentry check?▼
Our plans support 120 to 2,000 pages per month depending on your plan. We crawl your site to discover pages automatically, prioritizing your most important content.
