Share your screen. Not your personal data.

Turns itself on the moment a screen share starts, then hides everything personal on screen — from card numbers to an email. Found and blurred on your device, never uploaded.

Smart Blur, feature by feature

A customer record in a browser. Smart Blur blurs its emails, phone numbers and card numbers, then a click, a drawn box and a text selection blur more. With Pro, Local AI blurs the names and addresses in a support ticket, and Share Shield blurs every tab and tab name when a screen share starts, and stops when it ends.

Emails, phone numbers, cards and more blur on their own, on any website.

Turns itself on in the tools you share through

Start the share from the web version and protection switches itself on — a tab, a window or your whole screen, it makes no difference. Share from a desktop app instead and the browser never sees it start, so turn blur on yourself; it still covers everything you capture.

Blurring afterwards does not work

Four ways data gets out once it is on screen.

  • Editing a recording Hours frame by frame, and one missed frame undoes the rest.
  • Blurs slide off Fixed boxes stop matching the data the moment the page moves.
  • A live call There is no afterwards. It has already been seen.
  • A screenshot Pasted into a ticket or a chat with the data still in it.

What it does

Every control in the panel above, in one line each.

  • Turns on with the share Protection applies the moment a browser tab starts being shared.
  • Patterns Emails, phone numbers and IDs covered as the page loads.
  • Keywords Add a word and every match on the page goes with it.
  • Click or drag Cover any element, or draw a box over a whole region.
  • On-device AI Finds names and addresses in plain sentences. Nothing uploaded.
  • Screenshots Capture with the blur already baked into the image.

Frequently asked questions

Quick answers about Smart Blur.

What is Smart Blur?

Smart Blur is a productivity and privacy browser extension that lets you blur parts of web pages so passwords, messages, or personal data stay hidden during screen shares or when someone glances at your screen.

Is Smart Blur free?

Yes — most of the features of Smart Blur is free. For pro features, there is a one-time purchase. You pay once and keep using the Pro features without any recurring fees

Where does my data go?

Nowhere. Smart Blur processes everything locally in your browser using WebGPU. No data is sent to any server. See the privacy policy linked on this page for full details.

Which screen sharing apps does Smart Blur support?

Smart Blur turns itself on when you start sharing a browser tab, and it has been tested with Google Meet, Zoom Web and Microsoft Teams. Other browser-based tools are likely to work too. One real limit worth knowing: browsers do not expose native application shares to extensions, so if you share a desktop app rather than a tab, Smart Blur cannot reach it.

Does the AI mode work offline?

Yes. The on-device AI runs entirely via WebGPU in your browser with no internet connection required after the initial model download.

    Loved the auto enabling feature as soon as I start sharing the screen. This saves me from OOPS moment in front of my colleagues and clients.

  • Chrome Web Store

    I have been using the Pro features. Saving my blur saves time for meeting preparation. Also liked the auto enabling the blur mode while sharing over Zoom web.
