About Nixel
Nixel covers sensitive data on the page before anyone else sees it.
Share your screen, take a screenshot or record a demo, and whatever should not have been on display is already hidden: API keys and access tokens, card numbers, email addresses and phone numbers, internal hostnames and private IP addresses, and people's names, addresses and organisations.
WHY IT IS DIFFERENT
Other tools make you point at the thing you want hidden. You pick the element, or write a CSS selector, or drag a box over it. That only works for what you already remembered was there, and the whole problem is what you forgot. Nixel finds it and covers it before you look.
THE SCREENSHOT EDITOR
Capture a page with every finding already covered, check what it caught, and export a PNG that is safe to paste into a ticket or a chat.
IT RUNS ON YOUR DEVICE
We run no servers. Page content is read in your browser and never transmitted. The optional language model that recognises names and addresses runs locally too, after a one-time download.
PRICE
Free for seven days, no card. After that it is $29 a year, and one licence covers three installs.
