Use cases

Three ways your screen leaks. One way to stop them all.

Built for the people who put their screen in front of cameras.

FOR CREATORS

Record once.
Edit zero blurs.

Stop editing rectangles in post. Whatever you marked is masked the moment your screen recorder catches it — footage hits the timeline already clean.

  • Hours saved on every long-form video.
  • No re-renders for an OTP you missed in row 14.
  • Premiere · DaVinci · Final Cut · CapCut — same setup.

00:00 hours of post-prod blur

FOR LIVE

The frame
nobody sees.

Zoom, Twitch, webinars. A pop-up lands, a tab switches, a delivery notification with your address slides in. Everyone sees it — except your audience.

  • Zoom · Google Meet · Twitch · YouTube Live · Teams.
  • Even your typing is masked while predictions confirm.
  • Pop-ups, notifications, accidental tab switches — all caught.
FOR PROS

Show your work.
Hide what's private.

Demos, tutorials, sales calls, internal trainings, screenshots in Slack. Anything you'd ever want to share — without leaking the parts you wouldn't.

  • Mask any column, any cell, any badge with one rule.
  • Same setup protects the whole team.
  • Audit-friendly — nothing leaves the browser.

Whichever you are — install is the same

How it works

From install to clean recording in two minutes.

01 Install 02 Two-minute setup 03 Record. Stream. Share

Add Blurward to Chrome. From second one, ninety percent of the leaks on every page are already covered.

Hit record. Go live. Share your screen. The setup you did once protects you on every site, every tab, every time.

Two minutes. Forever.

Six features. One job.

Everything Blurward does on every page you open.

Frame-perfect masking

Hidden before the page paints. No flash. No flicker. Your camera and your audience never see it.

Predictive while you type

Your input stays masked until Blurward confirms it doesn't match. Your password is never readable — not even for one keystroke.

90% covered out of the box

Emails, cards, IBANs, phones, IDs, API keys, JWT, money, URLs, IPs, password fields. All on by default.

Custom terms in seconds

Any word, phrase or pattern. Catches every casing, every accent, mid-typing variants. `Project Nebula`, `project-nebula`, `ProjectNebula` — all caught.

Right-click magic

Right-click a salary cell, a customer name, a subject line — pick "Mask similar elements". Every match across the site, forever.

100% local

Your terms, your pages, your matches — none of it leaves your browser. No servers reading what you type. No analytics.

Predictive masking

Your password is masked before you finish typing it.

Blurward doesn't wait for Enter. Your input stays masked until it's confirmed safe — if it matches a sensitive term, it stays hidden until you clear the field.

Nothing you mask ever leaves your computer.

Every term you add, every page it scans, every match it finds — stays in your browser. There's no server. There can't be one.

100% of your data, masked.

Most people are 100% covered with the defaults alone. For anything specific to your workflow, add a rule or right-click — under a minute, forever.

Already on, out of the box

The defaults cover what 9 out of 10 leaks look like. No setup required.

Emails Credit cards IBAN API keys JWT tokens Phone numbers Monetary values DNI / NIE / SSN Passwords Login fields

Anything else? Two paths, both fast.

  • Right-click to mask every similar element.
  • Type a custom term once in settings.

FAQ

Frequently asked questions.

Does Blurward send anything to a server?

No. Everything runs in your browser. There is no Blurward backend that watches your screen or stores your terms.

Will it slow down my browser?

No noticeable cost on normal pages. Heavy mailbox-style pages with thousands of matches stay smooth thanks to per-block batching and caching.

What's the watermark?

On the free tier, masked spans show a small `Blurward` badge. It exists so you can see the protection working. Pro removes it. Protection itself is identical on both tiers.

What happens if I uninstall Blurward?

All your rules and settings are stored locally inside Chrome. Uninstalling deletes them. We can't recover them — there's nothing on our side to recover.

Does it work on every site?

Yes. Gmail, Stripe dashboards, Notion, Twitter/X, Slack, Discord, GitHub, your internal CRM, your bank — basically every web app you open. The masking applies before the page paints, so there's no flash of unmasked content. Works inside chat windows, embedded views and Google's apps too.

What about Firefox / Safari / Edge?

Chrome and Edge today (both Chromium). Safari is on the roadmap. Firefox after Safari. VS Code extension comes after the browsers.

Can my company use it?

Yes — Team plan in Pricing. Centralised policies, audit log, basic SSO.

Is it open source?

The detection core is MIT on GitHub. The packaged extension is freemium so we can fund maintenance — same model as Obsidian.

What about regulated industries?

Blurward is audit-friendly (everything stays local), but we don't certify GDPR / HIPAA compliance. Pair Blurward with your existing controls.

Will my password ever flash on screen for a frame?

No. Predictive masking keeps it hidden from the first keystroke.

Two minutes from now

Stop hoping you don't slip up. Just install it.

Record everything. Slip up nothing.
