PoHA (Proof of Human Attention) is a Chrome extension that lets you prove your messages were typed by hand, not generated by AI.
HOW IT WORKS
As you type in any text field — Gmail, X/Twitter, LinkedIn, or anywhere else — PoHA quietly observes your typing patterns: rhythm, pauses, corrections, and keystroke dynamics. These signals build a confidence score shown as a floating indicator next to your compose box.
When the indicator turns green, click it to badge your message with a short verification link (e.g. poha.ink/abc12). Anyone can click that link to verify the attestation is authentic.
WHAT GETS MEASURED
• Typing rhythm and inter-keystroke timing
