I built a free Chrome extension after seeing someone accidentally open an adult site while screen sharing
A few days ago, I saw a post from Bhoomika on X that made me stop scrolling.
She was on a work call with a CEO and sharing her screen. The CEO asked her to check a lead’s website. She searched the domain, clicked it—and an adult website opened on her shared screen.
Funny in hindsight. Terrifying when it happens during a client call, sales demo, interview, support session, or investor meeting.
This was the post that inspired ScreenGuard (https://x.com/buildwbhoomika/status/2098290218466251134).
I read the replies and realized this is not a rare problem. When we share our screens, a single misleading link, typo, unexpected redirect, personal tab, or visible API key can create an uncomfortable moment very quickly.
So I built ScreenGuard: a free Chrome extension that adds a safety layer to browsing, especially while screen sharing.
It can:
- Warn before suspicious or risky links open
- Detect phishing-style and misleading lookalike domains
- Block known adult or unsafe sites based on your protection settings
- Blur sensitive information such as API keys, tokens, card numbers, and email addresses while screen-share protection is enabled
- Run locally in your browser—your browsing activity and page content are not sent to a server
ScreenGuard is currently free and at v1.0.15.
I’m looking for early users and honest feedback—especially from founders, freelancers, sales teams, support teams, recruiters, educators, and anyone who shares their screen often.
A few questions I’m trying to answer:
- Have you had an “I wish that had not appeared on my shared screen” moment?
- Which would be most valuable to you: risky-link warnings, adult-site blocking, phishing protection, or sensitive-data blurring?
- What would make you trust ScreenGuard enough to keep it installed?
- What would make it annoying enough to uninstall?
I’m early, so blunt feedback is genuinely useful. I would rather learn what people need now than spend months building the wrong thing.
