Smart Blur compared with other blur extensions
There are a handful of browser extensions that blur data before you share your screen. Here's how Smart Blur differs from the popular ones. We make Smart Blur, so every fact about the others comes from their own websites and Chrome Web Store listings, checked on 26 October 2026.
What Smart Blur does differently
-
Finds data for free
Patterns blur emails, phone numbers, card numbers and other formats as the page loads. In most alternatives that's paid, or not there at all.
-
Custom patterns
Describe your own ID formats ("starts with ORD-, then 6 digits") or write a regex, test it, and limit it to certain sites. Free, with no limit. How it works
-
Local AI Pro
Finds names and street addresses written in ordinary sentences, where no pattern can. Runs entirely on your computer; nothing is uploaded.
-
Share Shield Pro
Switches blurring on in every tab the moment you share from the browser in Meet, Zoom or Teams on the web, and off when you stop.
-
Screenshot Pro
Capture the page or a region with the blur already in it, copied to your clipboard.
Smart Blur against one extension
- Smart Blur vs ZeroBlur The most-installed blur extension: free and simple, but you click everything yourself.
- Smart Blur vs BlurWeb Polished hand tools behind a paid licence. Smart Blur has them free, plus detection.
- Smart Blur vs DataBlur The closest match: detection, regex and an auto-start mode, mostly on Pro, and no AI.
- Smart Blur vs Safe Screen Share Detection, on-device AI and a call-start mode, all behind a licence. Smart Blur's detection and custom patterns are free.
Side by side
"Pro" means the feature needs the paid plan. "Not stated" means the product's listing doesn't say, not that it's missing.

When another extension fits better
If you use Firefox, ZeroBlur, BlurWeb and DataBlur all have Firefox versions; Smart Blur runs on Chrome, Edge and other Chromium browsers. If you need solid black boxes rather than blur, DataBlur offers them. And if you only ever blur a few fixed things by hand, ZeroBlur is free and simple.
If the data on your screen changes from call to call, you have your own ID formats to hide, or you want AI to catch names and addresses on your own computer, that's what Smart Blur is built for.
