Real event intelligence

Every layer is built to be genuinely correct.

Genuinely built — check-in, dashboard, analytics, AI.

検

Verified presence

Rotating, signed QR tokens plus GPS-accuracy-aware geofencing deliver genuinely verifiable presence.

Live, right now

Socket-based dashboards update the moment someone checks in — attendee count, rate, and timeline redraw instantly.

知

Grounded intelligence

Exact statistics computed deterministically, with AI dedicated purely to interpreting and explaining them.

組

Built for organizations

Multi-tenant from day one — organizations, roles, and events, with backend-enforced authorization throughout.

The flow

Raw check-ins become decisions.

Attendance → information → insight → recommendation → action.

  1. 1Organizer publishes an event with a geofenced venue and rotating QR.
  2. 2Attendee scans, shares location, and gets an honest distance readout.
  3. 3Backend verifies token + geofence + timing, records attendance once.
  4. 4Dashboard updates live — count, rate, and arrival timeline redraw instantly.
  5. 5AI layer explains anomalies and answers questions grounded in exact data.

Just need a QR code?

Posters, Wi-Fi cards, contact links — design one in QR Studio. No account, nothing leaves your browser, and it checks that your code actually scans before you download it.

A static code can be screenshotted and shared. For attendance, Kehai's signed, rotating, location-checked QR is the one that proves presence.
