Blur it beforeyou share it.
One click hides the salary column, the API key, the client name — right in the page, so your Zoom, Meet or Loom capture only ever sees the blur.

You meant to share one tab. They saw everything else.
You share your screen to walk through a chart. In the same window sits a payroll tab, an API key in your terminal, a client you’re under NDA with — and the Slack DM that lands mid-call. By the time you notice, the room has already seen it.
Tidying tabs and closing windows beforehand is the usual fix, and it fails the moment something new appears. BlurFirst lets you hide the sensitive part and keep working in your real layout — and blur anything else the instant it shows up.
Three gestures. That’s the whole product.
No modes to learn, no fields to configure. The demo above is the real thing — these are the gestures it uses.
Box
Drag a rectangle over anything — a chart, a region, a paragraph. It frosts over and stays locked to that content as you scroll.
Element
Hover to highlight, click to blur a single element — a cell, a header, a card. Click it again to bring it back.
Panic
One shortcut blurs the whole page — for the moment a DM slides in while you’re already sharing.
Now it finds the sensitive parts for you.
One click on Scan and BlurFirst sweeps the page for the things you’d never want on a call — and blurs them instantly. No hunting field by field.
Smart, and still private. Detection runs entirely in your browser — the page is matched locally and nothing is uploaded, not even to find it. That’s something cloud-based scanners can’t promise.
Built for the share you’re about to start.
Zero config
Install and blur. Nothing to set up.
Both gestures
Box for regions, element for precise fields.
Per-site profiles
Blur a dashboard once; it re-applies.
100% local
Rendered in the page. Nothing is uploaded.

A fair comparison of common methods, not specific products. The workarounds work — they just cost you your layout or miss what pops up next.
Built for anyone who shares a screen.
Pick the call where one stray tab, a client’s name, or a single secret would hurt most — blur that first. From there it’s second nature.
See all use casesThe blur stays in your browser. So does everything you blur.
Rendered, never captured
The blur is painted into the page, so screen-share and recordings capture the blurred pixels. BlurFirst never screenshots or uploads what’s on screen.
One network call, ever
The only request it makes is checking a license key — on activation and an occasional re-check. That’s it.
Stores selectors, not secrets
Per-site persistence remembers which element you blurred, never the content inside it.
Blur beyond the browser.
The extension hides what’s inside a browser tab. The BlurFirst desktop app will blur anything on your screen — native apps, other windows, notifications, your whole desktop.
$5 a month. Cancel anytime.
The yearly plan ($49) includes a 5-day free trial — your card isn’t charged until it ends. Or go lifetime: 30% off for the first 100 buyers.
Questions, answered honestly.
Does it work with Zoom, Google Meet, Loom and recordings?
Yes — with all of them. The blur is real pixels in the page, so anything that captures the page captures the blur, including recordings. BlurFirst doesn’t hook into any specific sharing tool.
Can BlurFirst detect sensitive data automatically?
Yes. Click Scan and BlurFirst finds and blurs common sensitive content in one pass — emails, phone numbers, credit-card numbers, SSNs and API keys. Detection runs entirely in your browser; nothing is uploaded. It’s a fast first pass that pairs with manual box and element blur for anything it doesn’t catch, like names in free text.
Can it blur apps outside the browser?
Not yet — the extension only affects what’s inside a browser tab. That’s exactly what the desktop app (in development) will do: blur native apps, other windows, and your whole desktop.
Is any of what I blur sent anywhere?
No. Everything you blur stays in your browser. The only network request BlurFirst makes is checking a license key, and only when you activate or on an occasional re-check.
Which browsers are supported?
Chrome, Edge, Brave, Vivaldi and Opera today. Firefox and Safari builds are in progress.
How much does it cost?
$5/month, billed immediately — cancel anytime. The yearly plan is $49 and starts with a 5-day free trial (your card isn’t charged until it ends). Lifetime is a one-time payment: $70 for the first 100 buyers, then $100.
Do my blurs stick around?
Per-site blurs persist between sessions and re-apply when you reopen BlurFirst on that site — and they survive in-app navigation that rebuilds the page.
