PixelHush

About

Protect API keys, tokens, passwords, database URLs, private keys, and personal data while recording demos, sharing your screen, or presenting live.

PixelHush works in two modes:

Manual mode lets you hide or reveal sensitive data on the current page at any time.

Automatic mode works with the PixelHush macOS desktop app and requires PixelHush Pro or an active trial. When a supported recording or screen-sharing app is detected, protection turns on automatically. When recording stops, protection turns off automatically.

How it works

PixelHush scans visible page text, form fields, textareas, and elements that match sensitive selectors. It also watches dynamic DOM updates and programmatic input changes, so protection keeps working in modern web apps and dashboards.

What gets protected

API keys, access tokens, passwords, and secret-looking values
Database URLs and connection strings
Private keys
Emails, IP addresses, SSNs, and credit card numbers
Custom selectors and regex patterns you define
Customize it

Edit detection rules in the popup, save your own JSON config, or import and export configs for different workflows.

Privacy

PixelHush processes page content locally in your browser. It does not send page content or detected secrets to any server. Automatic mode communicates only with the local PixelHush desktop app over localhost.
