Nixel finds API keys, card numbers, emails and personal details on any page and covers them up. Then you screen-share, screenshot or record without thinking about it.
Free for seven days, then $29 a year. No card to start, no account, nothing to configure.
Press any mask to look under it. The original never leaves the page.
Nixel does not send the pages you visit anywhere, because there is nowhere to send them: we run no servers. Detection runs inside your browser, in your own machine's memory.
That is not a promise about how carefully we handle your pages. It is a statement that we never receive them.
The popup tells you what it found, and one tap stops it hiding any kind you don't care about.
Right now you crop it, or you smudge it in Preview, or you look at it twice and send it anyway. All three depend on you spotting the thing you are trying not to send.
Nixel captures the page and opens an editor with every finding already covered. You review what it caught rather than hunt for what you missed. Toggle any of them, pick how a mask looks, then copy or save a PNG that is safe to paste into Slack, a ticket or a reply.
