MailHush

Anthropic shipped Claude
with your email exposed.
So we cleaned up their mess.

Claude leaves your email sitting in the DOM like that's somehow acceptable. Stream your screen? Post a screenshot? nice, now random weirdos have your inbox because Anthropic couldn't ship one basic privacy toggle.

How it happens

The live stream moment

You open Claude on stream to flex your prompt skills. Anthropic leaves your email sitting in the corner the entire time. 2,000 people now have it because nobody at HQ found this embarrassing enough to fix.

The screenshot post

You share a cool Claude conversation on Twitter. Forgot to crop the header. Your email is in 47 quote tweets before you notice, because Claude insists on wearing your identity like a name tag.

The team demo

Screen-sharing Claude in a meeting with clients. Your personal Gmail is right there. Very professional. incredible product instinct from the people who somehow missed this.


MailHush replaces emails
before anyone sees them.

A tiny browser extension that swaps email addresses in the DOM with whatever you want. No broken layouts. No page reloads. Just quiet, in-place replacement for a problem Anthropic should've solved themselves.
