Works on every site.
No setup per page. Install once and sensitive text is hidden everywhere — even when sites load new content after the page opens.

What it hides
Ten kinds of trouble.
Auto Blur knows what secrets look like. It spots them on the page and covers them before you notice them yourself.

Features
Small extension,
real peace of mind.
A dozen things it does well. Nothing extra. Every feature exists because real people have lost real minutes fumbling with screenshare when a credential flashed on screen.
Blurs before you can slip.
Smart Auto-Blur watches the three risky moments: when a supported browser screen share is detected, open supported tabs blur. Switch away, the tab behind you blurs. Step away from your desk, everything blurs. Enable the triggers you need and check your page before presenting.
Money mode.
One switch hides every ₹, $ and € amount on the page. Demo your dashboard without demoing your revenue; show a bank portal without the balance.
Made for Indian screens.
Aadhaar (checksum-verified, so random numbers don’t trigger it), PAN, UPI IDs and IFSC codes are detected out of the box — not just US formats.
Input fields too.
API keys don’t sit in paragraphs — they sit in settings-page text boxes. Turn on input scanning and those get covered as well, revealing only while you type in them.
One-key panic.
Someone walks up mid call? Press Alt + Shift + B and the whole page goes dark. Press again to bring it back.
Click to peek.
Need to double-check a value? Click any covered item to see it for three seconds, then it covers itself again.
Remembers your choices.
Something covered that shouldn’t be? Add it to your always-show list. The value itself never leaves your device — only a fingerprint that cannot be reversed.
Per-site control.
On a site where you need the values visible? Pause Auto Blur for 15 minutes or turn it off on that domain entirely. Everywhere else keeps running.
Draw a box over anything.
Maps, charts, canvases, embedded widgets — drag a rectangle over it and it stays blurred on that site, every visit, even after reloads.
Right-click, gone.
Select any text, right-click, Blur selection. Done. Pro keeps it blurred on every future visit — and the text itself is saved only on your device, never synced anywhere.
Live counts.
Open the popup to see exactly how many values are hidden on the page right now, broken down by type.
How it works
Three steps.
One minute.
1
~30sInstall it.
One click from the Chrome Web Store. No sign up, no email, no setup.
2
always onBrowse like normal.
Auto Blur runs quietly in the background. You won’t notice it’s there.

Keys, passwords, emails, card numbers — covered in real time. Click any one to peek anytime.
Need to hide everything, right now?
Press the panic shortcut and the entire page goes dark.

Privacy by design
Your data
stays yours.
Auto Blur was built by people who do not want their own data collected, tracked, or sold. That is not a slogan. It is a design choice we made before we wrote the first line of code.
Detection on your computer
- 01No account, no login.
Activate with your purchase code. No separate account or password.
- 02Detection stays on your device.
Page content is processed locally. Paid license refresh contacts our server with your signed code, which contains your purchase email.
- 03No tracking.
No analytics, no pings, no metrics. Not even how many times you use it.
- 04Local exceptions.
Always-show exceptions use local hashes, short display hints and site information. Hashes are not encryption; predictable values can be guessed.
- 05Browser-enforced.
Page access enables local detection. Storage, activeTab, tabs, idle, alarms and contextMenus support settings, controls, automation and license refresh. Browser sync can copy settings between your devices.
Why it exists
Built for the moment
you can’t rewind.
The six-hour pair session
You share your screen all day. Auth headers, .env files, staging URLs with tokens in them — they drift through your tabs whether you notice or not. Auto Blur notices.
The live client demo
One production API key on screen for four seconds is a rotation afternoon and an awkward email. Money mode plus site rules means your dashboard demos show the product, not the revenue.
The open-plan office
Someone rolls their chair over mid-Slack. One key — Panic Mode — and everything sensitive is already covered. No alt-tabbing, no explaining.
Pricing
One accident costs more
than a year of this.
Every plan includes everything. Unhappy within 7 days of your first purchase? Full refund, no questions — that’s your risk-free trial.
