Different problem

Two tools that look similar and are not

They appear in the same searches, and comparing them head-on would be unfair in both directions. Here is what they actually do.

Blur & Lock (Hotzapp)

WhatsApp Web only. Blurs chats automatically after inactivity, restores on mouse movement, and adds an optional PIN lock. Free, with a 4.9 star rating from 83 ratings and about 7,000 users as of August 28, 2026.

Where it fits: If the only thing you ever need to hide is WhatsApp Web from shoulder-surfers, this dedicated tool does that one job well. It does not blur other sites, and it is not a screen-share redaction tool.

Privacy Screen (blurmo.de)

A step-away tool: it blurs or shields the page after inactivity, tab switches, or idle, with saved element masks and privacy zones in its Premium tier ($14.99 a year, non-renewing). About 3,000 users and a 3.9 star rating from 11 ratings as of August 28, 2026.

Where it fits: It protects an unattended screen from people walking past. Its own FAQ states it does not prevent screenshots or recording, so it solves shoulder-surfing, not screen-share redaction.

How to actually choose

Start with three questions. First: do you blur things once in a while, or the same things every day? Occasional manual blurring is free in several of these tools, and ZeroBlur or Blurr.ing's free tier will serve you indefinitely. Daily repeated blurring is an automation problem, which is what DataBlur, Smart Blur and Blurr.ing Premium actually sell.

Second: does anything outside the page leak? If you share whole windows, your tab strip is visible, and Blurr.ing is the only tool in the table that masks tab titles and favicons. If notifications are your risk, no extension can help; that is an operating system setting, and our screen share privacy checklist covers it.

Third: which browser? Firefox rules out Blurr.ing, ContextBlur and Smart Blur immediately. Chromium browsers (Chrome, Edge, Brave, Arc) keep every option open.

FAQ

Choosing a blur extension, answered

Which blur extensions have a genuinely free tier?
ZeroBlur is entirely free. Blurr.ing gives unlimited manual blurs (box, element, text selection) free with no watermark and no account, with automation paid. DataBlur has a free tier with a visible badge on every blur. ContextBlur allows five free blurs per session. Smart Blur has a free tier with its AI detection gated to Pro. BlurWeb ($67+) and Blur It ($49.99) have no free tier at all, as of August 28, 2026.
Which ones keep blurs after a page reload?
Most persist blurs on revisit in some form: ZeroBlur (free, per page or site), ContextBlur (including free-tier blurs), BlurWeb (Keep Blur), Blur It, DataBlur (per-site profiles in Pro), Smart Blur (per-URL rules in Pro), and Blurr.ing (Premium). The distinction Blurr.ing documents is timing: saved blurs re-apply before the page first paints, so a reload never flashes the hidden content; other tools do not advertise their paint timing.
Which extensions detect sensitive text automatically instead of requiring a click per item?
Four claim automation: DataBlur (emails, phones, names, cards, API keys, plus custom regex), Blurr.ing (34 documented pattern presets plus custom keywords with AND/OR/NOT, in Premium), Smart Blur (on-device AI recognition of names, addresses and organizations, in Pro), and Blur It (advertised for emails, numbers and IDs). ZeroBlur, BlurWeb and ContextBlur’s free tier are manual; ContextBlur Pro advertises auto-blur without itemizing categories.
Which work outside Chrome?
ZeroBlur, BlurWeb and DataBlur publish Firefox builds and support Edge. Blurr.ing supports the Chromium family: Chrome, Edge, Brave and Arc, with no Firefox version. ContextBlur and Smart Blur list Chrome only. None of these tools can blur anything outside a browser page: desktop apps, games and OS notifications are beyond all of them.
Why is there no "winner" on this page?
Because the honest answer depends on what you need: ZeroBlur if you want free manual blurring and do not mind a tool last updated in September 2024; DataBlur if you want regex rules and Firefox; Smart Blur if you want local AI detection; ContextBlur if you want the cheapest subscription; Blurr.ing if you want unlimited unwatermarked free manual blurring, documented presets, Tab Privacy and a $39 lifetime. The per-tool pages linked above mark the rows each competitor wins.
