The human signature for the AI age
One tap says: I read this, and I stand behind it.
Anyone — or anything — can send a message now. The stamp shows a person paused, read it, and put their name on it.

What they quietly wonder when your message lands
severity 1 → 401 · mild“Is this a mail-merge?”A programmatic blast with your name dropped in.
02 · medium“Is this an agent replying?”An AI agent answering on their behalf. No human in the loop.
03 · serious“Did they even read it?”Pasted, dumped, and sent. Will they stand behind it tomorrow?
04 · severe“Is this even them?”An impersonator, a deepfake, a doctored screenshot.
One tap clears all four.
Not a blast, not an agent. You read it before it went out.

really from you
The oldest gesture of trust, returned
For centuries, letters were signed and sealed — a unique mark that gave the message credibility. Seeing it broken meant a person had pressed their name into the wax.
Your stamp is that gesture again. A little friction on purpose — two seconds of it — is exactly what makes it feel more human.
