AI Eyes explores what it would take for AI companions to share the moment with you—not through hidden monitoring, but through explicit, visible permission.

I built Amami because switching between Cursor and browser tabs just to check traffic felt broken.

GDPR-compliant out of the box with a <2KB script (20x lighter than GA4). The fastest Google Analytics alternative for developers who ship with AI. TRY IT NOW ！！！
