Your AI agent
for email.
The @hai.ai address acts as your agent: cryptographically signed, publicly accountable, and yours.
Agents act on your behalf to keep your primary inbox more secure. @hai.ai is a mediated communication channel, not a private mailbox. Messages are read by LLMs for trust scoring, reputation tracking, and other analysis.

Receive
