Nixel: Hide Sensitive Data Before Screen Sharing

Hide API keys, emails and personal details before screen sharing, recording or screenshots. Detection runs on your device.

Nixel hides API keys, emails and personal details in Chrome before you share your screen, record a walkthrough or send a screenshot. Open the extension on the page you want to show, review what it found and choose which details to cover. Detection happens on your device. Choose what stays private • API keys, access tokens and AWS credentials • Card numbers, checked against a checksum and issuer prefix • Email addresses and phone numbers • Internal hostnames and private IP addresses • Names, addresses and organisations, with the optional local language model Make the masks fit your demo Choose blur, pixels, solid bars or labels. Turn detection categories on or off from the popup so you can keep the information you need to discuss visible. Check screenshots before sending them Capture the visible page area and open Nixel's screenshot editor with detected items covered. Review individual findings, choose a mask style, then copy or save a PNG for a support ticket, message or reply. Page content stays on your device Nixel processes page content inside your browser. It isn't sent to us or an AI service. The optional model for names, addresses and organisations downloads once (about 100 MB), then runs locally. Licence checks go to Lemon Squeezy without page content. Try it on your own pages Free for 7 days, with no payment card required. After the trial, a licence costs $29 a year and covers 3 installs. A final check still matters Detection can miss sensitive details or cover text you wanted to show. Nixel works with supported text on Chrome pages, not other apps or your whole desktop. Don't rely on it to detect text inside images or videos. Review the page and any exported screenshot before sharing.
