Sign emails that you engaged with to stand out in Gmail and Outlook. Effort used to mean something. A thoughtful cold email, thank-you note, or introduction was once a signal that someone had invested real time in reaching out. Today, with AI generating polished messages in seconds, that signal is gone — what once took personal investment can now feel like a ChatGPT prompt, a copy & paste, and a send. So how do you stand out in someone's inbox when effort is invisible? HumanStamp restores the value of this effort. HumanStamp is a Chrome extension for Gmail and Outlook that watches how your email is written — not what it says. When you've personally typed over 50% of a message, it lets you cryptographically sign it with a HumanStamp badge before sending. For recipients of your email, that badge is a verifiable guarantee: 1. The message was majority human-typed 2. The content hasn't been altered since it was signed 3. The verification is backed by cryptography, not a company's word Hover over any badge (with the extension installed) and see the proof yourself. AI-generated communication is inevitable, and HumanStamp doesn't fight this. It simply makes human effort visible again — for the people who still think it matters.
