NixelSharing your screen
Walk through a dashboard with a client or a teammate. Cover detected emails, phone numbers and credentials in the browser tab you're sharing.
A little privacy before you press Share
Hide what shouldn't
be shared.
Your next demo doesn't need your API key in it. Nixel finds sensitive text in Chrome and covers it before you share your screen, record a walkthrough or send a screenshot.

Nixel hides sensitive data before you share your screen. Choose blur, pixels, solid bars or labels. Turn name masking off while keeping the other masks, then turn it back on. Open the screenshot editor and review the masks before saving or sharing.

What gets covered
The small things
you might miss.
Open the extension to see what it found. You can switch detection categories on or off and choose how the masks look.
- API keys and access tokensIncluding common credential formats and AWS keys.
- Card numbersChecked against a checksum and issuer prefix.
- Emails and phone numbersContact details in the page you're showing.
- Private IPs and internal hostnamesDetails that can slip into a technical demo.

It stays on your side of the screen
Detection happens on your device.
Page content is processed inside your browser and isn't sent to us or an AI service. The optional language model is a one-time download of about 100 MB. Once downloaded, it runs locally too.
Licence checks go to Lemon Squeezy and don't include page content. Read the privacy policy.
Before you install
A few useful details.
Does it work with Zoom, Google Meet or Loom?
Nixel masks text in Chrome pages. Those masks can appear when you share or record that browser tab with your meeting or recording tool. Nixel doesn't mask other apps, browser controls or your whole desktop. Check the shared view before starting.
Do I need to download the language model?
No. Pattern-based detection covers supported credentials, card numbers, emails, phone numbers and network details without it. Enable the optional local model if you also want to detect names, addresses and organisations.
Will it catch everything?
Detection can miss sensitive details or hide text you wanted to show. Nixel works with supported text on web pages; don't rely on it to find text inside images or videos. Review your page and any exported screenshot before sharing.
What happens after the free trial?
The trial lasts 7 days and needs no payment card. A licence costs $29 a year and covers 3 installs. See pricing and licence details.
